Day Neutral Varieties

UC Keystone Cultivar

This is a new day neutral cultivar from the UC Davis Strawberry breeding program. The initial breeding cross originated in 2017 and the selection 17C138P062 was made. It was subsequently tested as that number from 2019-2022. This cultivar is a mid to late-season day neutral variety with excellent post–harvest qualities.

UC Keystone produces equal to higher yields and % marketable fruit relative to UC’s four main commercial day neutral cultivars (Monterey, Cabrillo, UCD Royal Royce, & UCD Valiant). Those four cultivars are all susceptible to Fusarium wilt whereas UC Keystone is resistant. It performs best in fall planted production systems, and it performs equally well when harvested with 400-600 chilling hours from high elevation nurseries and planted directly with no post-harvest chill versus plants given 10-17 days post -harvest chill. Fruit is firm which supports better post -harvest keeping qualities.

UC Keystone is resistant to Fusarium wilt (Fusarium oxysporum), moderately resistant to Verticillium wilt (Verticillium dahlia) and Phytophthora crown rot (Phytophthora cactorum), and moderately susceptible to Charcoal rot (Macrophomina phaseolina).

Nursery clone productivity for UC Keystone is equal or superior to that of Monterey, a well-known day neutral cultivar as a comparison.

The UCD Valiant Cultivar (PDF)

This is a new day neutral cultivar released from the UC Davis Strawberry breeding program. The initial breeding cross originated in 2011 and the selection 11C103P001 was made. It was subsequently tested as 16DN011 from 2016-2018. This cultivar is an early season day neutral variety that excels in the southernmost day neutral growing regions of California and in organic and lower input growing environments.

Valiant produces significantly higher yields and % marketable fruit relative to UC’s three main commercial day neutral cultivars (Cabrillo, Monterey and San Andreas). It performs best in fall planted production systems, but performs equally well when harvested with 400-600 chilling hours from high elevation nurseries and planted directly with no post harvest chill versus plants given 10-17 days post harvest chill. The plant is more vigorous in growth habit and the plant performs better in lower input growing environments producing larger fruit size. Fruit is firmer than the check commercial cultivars, which supports better post harvest keeping qualities.

Valiant is moderately resistant to Verticillium wilt (Verticillium dahlia), moderate susceptibility to Phytophthora crown rot (Phytophthora cactorum), and susceptible to Fusarium wilt (Fusarium oxysporum), and Charcoal rot (Macrophomina phaseolina).

Nursery productivity for Valiant is superior to that of San Andreas, a well known day neutral cultivar, as comparison.

UCD Royal Royce Cultivar (PDF)

This is a new day neutral cultivar released from the UC Davis Strawberry breeding program. The initial breeding cross originated in 2008 and the selection 08C123P001 was made. It was subsequently tested as 16DN009 from 2016-2018. This cultivar is a early to mid-season day neutral variety with excellent post harvest qualities.

Royal Royce produces significantly higher yields and % marketable fruit relative to UC’s three main commercial day neutral cultivars (Cabrillo, Monterey and San Andreas). It performs best in fall planted production systems, but performs equally well when harvested with 400-600 chilling hours from high elevation nurseries and planted directly with no post harvest chill versus plants given 10-17 days post harvest chill. One critical advantage to Royal Royce is a significant reduction of runners during the berry growing season which results in a significant reduction in field production costs for growers who need to cut runners to manage for higher fruit yields. Fruit is firmer than the check commercial cultivars, which supports better post harvest keeping qualities.

Royal Royce is moderately resistant to Verticillium wilt (Verticillium dahlia) and has moderate susceptibility to Phytophthora crown rot (Phytophthora cactorum), Fusarium wilt (Fusarium oxysporum), and Charcoal rot (Macrophomina phaseolina).

Nursery productivity for Royal Royce is equal or superior to that of San Andreas a well known day neutral cultivar as comparison.

The UCD Moxie Cultivar (PDF)

This is a new day neutral cultivar released from the UC Davis Strawberry breeding program. The initial breeding cross originated in 2011 and the selection 11C141P001 was made. It was subsequently tested as 16DN012 from 2016-2018. This cultivar is a full-season day neutral variety excelling as the season goes on with excellent post harvest qualities.

Moxie produces significantly higher yields and % marketable fruit relative to UC’s three main commercial day neutral cultivars (Cabrillo, Monterey and San Andreas).
It performs best in fall planted production systems, but performs equally well when harvested with 400-600 chilling hours from high elevation nurseries and planted directly with no post harvest chill versus plants given 10-17 days post harvest chill. Because of the ability of the cultivar to yield late into November/December under this culture system, it may fill a product niche as a competitor to Portola, which is grown in a summer plant system. One critical advantage to Moxie is a significant reduction of runners during the berry growing season which results in a significant reduction in field production costs for growers who need to cut runners to manage for higher fruit yields. Fruit is firmer than the check commercial cultivars, which supports better post harvest keeping qualities.

Moxie is resistant to Fusarium wilt (Fusarium oxysporum), moderately resistant to Verticillium wilt (Verticillium dahlia), moderate susceptibility to Phytophthora crown rot (Phytophthora cactorum) and and susceptible to Charcoal rot (Macrophomina phaseolina).

Nursery productivity for Moxie is equal to that of San Andreas a well known day neutral cultivar as comparison.

The Monterey Cultivar

Monterey is moderate in day-neutrality, slightly stronger flowering than Albion with a similar production pattern. It is a vigorous plant and may require slightly more space than Albion. The fruit for Monterey is slightly larger but less firm than for Albion. Post-harvest traits for Monterey are similar to those for Albion. Monterey has outstanding flavor with a distinct sweet aftertaste that is unique among California cultivars. Monterey has a good disease resistance profile, although it is susceptible to powdery mildew (Sphaerotheca macularis); this disease will require close control by both nursery and fruit growers in order to farm this cultivar successfully. Nursery productivity for Monterey is exceptional.

The Cabrillo Cultivar

The Strawberry Breeding program at UC Davis has released a new day-neutral cultivar originating from a cross performed in 2008: Cabrillo, formerly identified as CN236 and originally referenced as Cal 8.181-1. This cultivar exhibits uniformly high productivity, greater than for San Andreas and Monterey, and is adapted to standard fall planting and winter production systems, as well as to spring and summer planting. This cultivar has overall fruit quality equal or superior to presently available day-neutral cultivars.

Cabrillo has slightly larger fruit and produces greater individual-plant yield than any of the comparison cultivars. It has a similar production pattern to Albion with most cultural treatments, although it is substantially more adapted to later-season winter planting and spring planting.  Commercial appearance ratings have been similar to or better than those for all of the comparison cultivars, especially better than Portola in summer planting systems; these superior appearance scores translate directly into a larger fraction of marketable fruit than is produced by the comparison cultivars.  Fruit for Cabrillo is firmer than fruit from the comparison cultivars.  Subjectively, Cabrillo has outstanding flavor.

Cabrillo is moderately resistant to powdery mildew (Sphaerotheca  macularis), and moderately susceptible to Anthracnose crown rot (Colletotrichum acutatum). It is moderately resistant to Verticillium wilt (Verticillium dahliae), Phytophthora crown rot (Phytophthora cactorum) and common leaf spot (Ramularia tulasnei). When treated properly, it has tolerance to two-spotted spider mites (Tetranychus urticae) equal to that for the comparison cultivars. Nursery productivity for Cabrillo is equal or superior to that for existing day-neutral cultivars.

The Albion Cultivar

Albion is a Day-neutral (ever-bearing) cultivar similar to Diamante. Fruiting plants of Albion are similar in size and vigor to Diamante, but more open, and more erect than plants of Diamante. Nursery source, chilling requirements, and planting dates should be very similar for Albion and Diamante.

Albion is quite resistant to Verticillium wilt (Verticillium dahliae) and Phytophthora crown rot (Phytophthora cactorum), and relatively resistant to Anthracnose crown rot (Colletotrichum acutatum). When treated properly, it has tolerance to two-spotted spider mites (Tetranychus urticae) equal or greater than Diamante. When treated with appropriate planting regimes, Albion has similar fruit size and produces equal or greater individual-plant yields than Diamante.

Fruit from Albion is firm, but slightly less so than fruit from Diamante. External and internal fruit color for Albion is darker than Diamante fruit. Subjectively, Albion has excellent flavor. The fruit will be outstanding for both fresh market and processing.

Commercial Availability

Strawberry producers can obtain Albion from commercial nurseries licensed by the University of California.  See Licensed Nurseries List.

The San Andreas Cultivar

San Andreas is a moderate day-neutral with a production pattern very similar to Albion. Plant vigor for San Andreas is somewhat higher than for Albion early in the season but plant size throughout the fruiting season is similar to Albion due to its high and consistent productivity. This cultivar produces few runners in the fruiting field.  Nursery productivity for San Andreas is similar to or slightly below that for Albion.

The fruit for San Andreas is exceptional in appearance and especially superior to Albion early in the season. The fruit color for San Andreas fruit is slightly lighter than for Albion, and it has similar post harvest characteristics. The flavor of San Andreas is outstanding, very similar to that for Albion. San Andreas has a good disease resistance profile with no outstanding cautions. Its typically high quality fruit early in the season, together with a low chilling requirement, make this a good candidate cultivar for southern California.

The Benicia and Mojave Cultivars

‘Benicia’ has moderate to high plant vigor, but is slightly smaller in plant size than ‘Ventana,’ with a similar production pattern. It may require slightly less space in the fruiting field than ‘Ventana.’ The fruit for ‘Benicia’ is slightly larger and slightly firmer than for ‘Ventana.’ Post harvest traits for ‘Benicia’ are similar to those for ‘Ventana,’ although the fruit is slightly darker and has a more evenly colored interior. ‘Benicia’ has very good flavor, substantially better than ‘Ventana’ in early spring. ‘Benicia’ has a good disease resistance profile, although it is susceptible to Verticillium wilt (Verticillium dahliae); this disease will require close control by both nursery and fruit growers in order to farm this cultivar successfully. Nursery productivity for ‘Benicia’ is superior to that for ‘Ventana.’

‘Mojave’ has moderate to high plant vigor, especially early in the season, but is slightly smaller in plant size than ‘Ventana’ throughout the season. With early fall planting, ‘Mojave’ has a similar production pattern to ‘Ventana.’ It may require slightly less space in the fruiting field than ‘Ventana.’ The fruit for ‘Mojave’ is substantially larger than for ‘Ventana,’ but is slightly less firm. Post harvest traits for ‘Benicia’ are similar to those for ‘Ventana.’ ‘Mojave’ has very good flavor, substantially better than ‘Ventana’ in early spring. ‘Benicia’ has a good disease resistance profile, although it is susceptible to Phytophthora crown rot (Phytophthora cactorum); this disease will require close control by both nursery and fruit growers in order to farm this cultivar successfully. Nursery productivity for ‘Mojave’ is superior to that for ‘Ventana.’

Commercial Availability

Strawberry producers can obtain Benicia and Mojave from commercial nurseries licensed by the University of California.  See Licensed Nurseries List.

The Ventana Cultivar

Ventana (C216) is a short-day (June bearing) cultivar similar to Camarosa. Fruiting plants of Ventana are large and vigorous, similar to Camarosa, but more open than plants of Camarosa; Ventana plants are larger and less erect than plants of Gaviota. Ventana is moderately susceptible to common leaf spot (Ramularia tulasnei) and Verticillium wilt (Verticillium dahliae). It is quite resistant to Phytophthora crown rot (Phytophthora cactorum), and relatively resistant to powdery mildew (Sphaerotheca macularis). When treated properly, it has tolerance to two-spotted spidermites (Tetranychus urticae) equal or greater than Gaviota and Camarosa.

When treated with appropriate planting regimes, Ventana has similar fruit size and produces greater individual-plant yields than Gaviota or Camarosa. In general, Ventana is well adapted to very early season planting. The production pattern for Ventana is similar to that for Camarosa: it initiates fruiting at the same time, but produces greater quantities of early-season fruit with most cultural treatments. Commercial appearance ratings have been better than those for Camarosa, and trials conducted in Santa Maria, CA in 1999-2000 indicate a fraction of non-marketable fruit that is less than half that produced by Camarosa.

Fruit for Ventana is slightly firmer than fruit from Gaviota but slightly less firm than Camarosa. External and internal fruit color for Ventana is lighter than Camarosa and Gaviota, with substantially brighter red coloration. Subjectively, Ventana has very good flavor. The fruit will be outstanding for both fresh market and processing.

The Benicia and Mojave Cultivars

‘Benicia’ has moderate to high plant vigor, but is slightly smaller in plant size than ‘Ventana,’ with a similar production pattern. It may require slightly less space in the fruiting field than ‘Ventana.’ The fruit for ‘Benicia’ is slightly larger and slightly firmer than for ‘Ventana.’ Post harvest traits for ‘Benicia’ are similar to those for ‘Ventana,’ although the fruit is slightly darker and has a more evenly colored interior. ‘Benicia’ has very good flavor, substantially better than ‘Ventana’ in early spring. ‘Benicia’ has a good disease resistance profile, although it is susceptible to Verticillium wilt (Verticillium dahliae); this disease will require close control by both nursery and fruit growers in order to farm this cultivar successfully. Nursery productivity for ‘Benicia’ is superior to that for ‘Ventana.’

‘Mojave’ has moderate to high plant vigor, especially early in the season, but is slightly smaller in plant size than ‘Ventana’ throughout the season. With early fall planting, ‘Mojave’ has a similar production pattern to ‘Ventana.’ It may require slightly less space in the fruiting field than ‘Ventana.’ The fruit for ‘Mojave’ is substantially larger than for ‘Ventana,’ but is slightly less firm. Post harvest traits for ‘Benicia’ are similar to those for ‘Ventana.’ ‘Mojave’ has very good flavor, substantially better than ‘Ventana’ in early spring. ‘Benicia’ has a good disease resistance profile, although it is susceptible to Phytophthora crown rot (Phytophthora cactorum); this disease will require close control by both nursery and fruit growers in order to farm this cultivar successfully. Nursery productivity for ‘Mojave’ is superior to that for ‘Ventana.’

The Grenada Cultivar

The short-day selection C232, has performed well in trials conducted at all three of the major production locations in California and has been assigned the designation Grenada. The qualitative assessments provided below represent the general consensus of UC breeders and grower cooperators that have evaluated these selections in trials conducted throughout California.

Grenada has greater total productivity than Ventana and Benicia in most systems and locations, and generally produces more early-season fruit than the comparison cultivars. Plants of Grenada are similar in size to Ventana and Benicia but, with early planting, tend to remain smaller during the season due to very high early fruit loads.

Grenada had substantially larger fruit, lower cull rates and/or higher appearance scores than Ventana in all locations, lower cull rates and/or higher appearance scores than Benicia. Harvest efficiency for Grenada is expected to be higher than Ventana and Benicia, due to larger fruit and lower cull rates. Fruit for Grenada is slightly firmer than Benicia fruit, substantially firmer than for Ventana. Importantly, the subjective evaluations of flavor and post-harvest storage capacity were excellent for Grenada. Grenada fruit has excellent fruit color as well, slightly darker both internally and externally than Ventana.

Grenada has variable reaction to soil and foliar diseases. Grenada is moderately sensitive to Verticillium and highly susceptible to Fusarium, but is moderately resistant to Phytophthora cactorum. Preliminary trials indicate that Grenada has substantial resistance to Macrophomina. It has good resistance to powdery mildew and seems tolerant of spidermites.

The Merced Cultivar

The short-day selection C229, has performed well in trials conducted at all three of the major production locations in California and has been assigned the designation Merced. The qualitative assessments provided below represent the general consensus of UC breeders and grower cooperators that have evaluated these selections in trials conducted throughout California.

Merced has total productivity similar to Ventana and Benicia in some systems and locations, but a production pattern more similar to Camarosa than the comparison cultivars. Specifically, Merced has similar total yield to Ventana and Benicia in central California locations, but slightly lower seasonal yield in southern California. Plants of Merced are smaller than for Ventana and Benicia and will tolerate increased planting density. Merced initiates crown division and flowering more slowly than Ventana and Benicia and will produce less early fruit when established on the same date in southern California.

Merced had substantially larger fruit, lower cull rates and/or higher appearance scores than Ventana and Benicia in all locations. Harvest efficiency for Merced is expected to be higher than Ventana and Benicia, due to larger fruit, lower cull rates and more compact plants, and this is especially important later in the season. Fruit for Merced is slightly firmer than Benicia fruit, substantially firmer than for Ventana. Importantly, the subjective evaluations of flavor and post-harvest storage capacity were excellent for Merced. Merced fruit has excellent fruit color as well, slightly lighter both internally and externally than Ventana.

Merced has variable reaction to soil and foliar diseases. Merced is moderately sensitive to Verticillium and Fusarium, but is resistant to Phytophthora cactorum. It has good resistance to powdery mildew and seems tolerant of spidermites.

Commercial Availability

Strawberry producers can obtain Merced from commercial nurseries licensed by the University of California.  See Licensed Nurseries List.

The Palomar Cultivar

In 2004-05 and 2005-06, Palomar produced similar early yield to Ventana at all locations, and exceeded seasonal yield for Ventana at Santa Maria (Table 1). Palomar had substantially lower cull rates and/or higher appearance scores than Ventana in all trial locations, with fruit size similar to that of Ventana. Importantly, firmness, and the subjective evaluations of flavor and post-harvest fruit quality were excellent for Palomar. In Irvine in 2005-06, Palomar had 26% greater early-season yield than Ventana, albeit with less total yield, but with greater fruit size and improved firmness. Preliminary results of 2006-07 field trials in Irvine indicate that Palomar produced 78% greater yield than Ventana (995 and 558 crates/acre for Palomar and Ventana, respectively) to January 18, 2007, with higher fruit appearance scores and a lower cull rate.

An additional feature of selection Palomar is that plant size is substantially smaller than that of Ventana, a factor that will permit increased planting density and facilitate harvest efficiency. However, with less vegetative vigor and a marked tendency to fruit heavily early in the season, growers in southern California may need to consider management practices that encourage plant vegetative growth, such as the use of clear polyethylene bed mulch and careful soil moisture and fertility management.

Strawberry producers can obtain Palomar from commercial nurseries licensed by the University of California.  See Licensed Nurseries List.

Summer Plant Varieties

UC Eclipse Cultivar

This is a new extreme day neutral cultivar from the UC Davis Strawberry breeding program. The
initial breeding cross originated in 2017 and the selection 17C242P023 was made. This cultivar is a
day neutral variety excelling in its use for summer plant culture but it has also performed very
well in Fall planted regions growing day neutral varieties.

UC Eclipse produces marketable yields significantly higher than Portola, the key cultivar in the
summer plant market segment. UC Eclipse produces large, firm fruit through the growing season with
higher % marketable fruit than Portola.

UC Eclipse is resistant to Fusarium wilt (Fusarium oxysporum), moderately resistant to Verticillium
wilt (Verticillium dahlia) and Phytophthora crown rot (Phytophthora cactorum), and is moderately
susceptible to Charcoal rot (Macrophomina phaseolina).

Nursery productivity for UC Eclipse exceeds that of Portola the key day neutral cultivar in the
summer plant market segment.

The UCD Finn Cultivar (PDF)

This is a new extreme day neutral cultivar from the UC Davis Strawberry breeding program. The initial breeding cross originated in 2012 and the selection 12C112P004 was made. It was subsequently tested as 17EDN015 from 2017-2019. This cultivar is a day neutral variety excelling in its use for summer plant culture.

Finn produces marketable yields similar to Portola, the key cultivar in the summer plant market segment. One critical reason for the advancement of this cultivar was to provide superior fruit quality to Portola to address consumer complaints with the quality of fruit coming from that cultivar. Fruit is 1% higher in sugar content and has firmer fruit than Portola, which supports better post harvest keeping qualities.

Finn is moderately susceptibile to Verticillium wilt (Verticillium dahlia), and susceptible to Phytophthora crown rot (Phytophthora cactorum), Fusarium wilt (Fusarium oxysporum), and Charcoal rot (Macrophomina phaseolina).

Nursery productivity for Finn is equal to that of Portola the key day neutral cultivar in the summer plant market segment.

The Portola Cultivar

Portola is a strong day-neutral cultivar with broad adaptability. This cultivar can be used in standard winter planting systems, where it is slightly earlier than Albion to initiate fruiting. Due to a strong flowering response Portola is especially well adapted to spring and summer planting systems. Portola has a vigorous plant and may require slightly lower plant density than Albion. The fruit for Portola is similar in size to Albion but lighter in color and somewhat shinier. Post-harvest characteristics for Portola are similar to those for Albion although it is slightly less tolerant to rain. Fruit flavor for Portola is excellent and especially consistent throughout the fruiting season. Portola has a good disease resistance profile with no outstanding cautions. Nursery productivity for Portola is exceptional.
