AROMAS-CN209 Top
Everbearer, released 1997 from UC Davis
The appropriate comparison cultivar here is Selva, which is still the predominant day-neutral cultivar in Watsonville/Salinas. All of the selections intended for release are superior to Selva for productivity, fruit quality, harvest efficiency, and environmental tolerance.
This is the most productive of the three day-neutral intended for release, initiates production somewhat later than the others and produces large quantities of fall fruit. It also has the broadest environmental tolerance, is most resistant to mildew that Selva, and was especially tolerant to spidermites in the past rather challenging season. The plant architecture facilitates harvest and pest control (rather erect habit). This has been the selection of choice for about 40% of the growers involved in our cooperative tests, and seems to show more promise than the others in the more inland trials. Flavor is very good, fruit size and cull rate are the weakest of the three, but are substantially better than for Selva.
CAMAROSA (US PATENT VARIETY) C-25 Top
Springbearer
Inventor, Voth, University of California.
Developed by the University of California and introduced in 1993 as a short-day strawberry cultivar, characterized by excellent early, mid-and late-season production of large, conical or flat-oblate-conical fruit, with excellent internal and external color. Camarosa firmness and fruit size are greater than Chandler, fruit is moderately rain-tolerant, and postharvest shipping and handling qualities are excellent. Plants are vigorous, with moderate susceptibility to Xanthomonas and powdery mildew. Camarosa best adapted to the Southern growing areas, producing consistent high yields of large fruit and good quality. More than any other variety tested, Camarosa is well-adapted to early nursery digging. Early production, high total yields, consistently large attractive fruit and good firmness; shipping and postharvest qualities make Camarosa and attractive variety for both growers and shippers. Camarosa firmness allows greater flexibility in scheduling fruit harvests, and well as flexibility in the market. In Southern California in 1995, Camarosa size, quality and firmness permitted fresh shipments in late May and June, something that would be difficult for most other short-day varieties. The Camarosa plant is more vigorous than Chandler, and production programs may need to be modified to maximize yield and fruit quality, and may benefit from a wider plant spacing than that used for Chandler. Camarosa appears to be more susceptible than Chandler to Colletotrichum fruit rot, Xanthomonas and powdery mildew. As with all varieties, the use of clean nursery stock is essential.
CAPITOLA (US PATENT VARIETY) Top
Everbearer
Inventor, Bringhurst, University of California.
Released by the University of CA, Davis, in 1991. Very large plants with slightly softer fruit than Seascape. This variety is well suited for warmer climates and produces very high yields of fruit in the fall.
CHANDLER (US PATENT VARIETY #5262) Top
Springbearer
Inventor, Bringhurst, University of California
A short-day variety released in 1983, this is presently the predominant variety in southern California and San Luis Obispo County plantings and is planted to a lesser extent in central counties. It accounts for 50 percent of the statewide acreage in 1989. Chandler is winter-planted in southern California and is used with both systems in central California. It has very high yielding, although it is not as early as Douglas and tends to have a sharper peak in production than Douglas. Fruit flavor and color are exceptional and firmness and shipping qualities are superior to Douglas, but not outstanding because it has a somewhat tender skin. Chandler fruit shape is similar to Douglas and not as seedy. A vigorous variety, high yields have been experienced throughout the Carolinas and California. Due to their lack of winter hardiness, this variety is not well suited for northern locations above the Mason-Dixon Line.Typical winter-planting recommendations are similar to those for Douglas, although Chandler has a somewhat high chilling requirement. Plant vigor can be low if chilling in the nursery is insufficient, and 1 to 2 weeks of supplemental storage are often beneficial. Alternatively, Chandler treated with more than 2 weeks of storage can be excessively vegetative, with substantially reduced yields. Summer-planting recommendations for this variety are similar to those for Pajaro, carrying the precaution that early plantings in coastal sites have reduced vegetative growth and have resulted in smaller fruit size.
DIAMANTE-CN210 Top
Everbearer, released from UC Davis in January 1997
The appropriate comparison cultivar here is Selva, which is still the predominant day-neutral cultivar in Watsonville/Salinas. All of the selections intended for release are superior to Selva for productivity, fruit quality, harvest efficiency, and environmental tolerance.
This selection produces very high quality fruit with a very low cull rate, and is probably the best flavored day-neutral item released by the UC program to date. Its production pattern is very consistent and the plant architecture facilitates easy harvest. This selection is tolerant to spider mites and mildew, but not to Anthracnose crown rot. This selection has received the greatest interest from growers: about 40% from central California and most of those from Santa Maria consider it their first choice. Two reservations: it tends to runner somewhat during fruiting and the internal fruit color is probably too light for the processing industry. This selection does not require the cold storage that Selva does, 10 to 18 days will be sufficient in most systems, and it will give reduced yields if treated with storage similar to that needed for Selva.
FERN (US PATENT VARIETY #5267) Top
Everbearer
Inventor, Voth, University of California
Released in 1983, is a strong day-neutral and has not been planted extensively in California. It has potential only in home gardens because it always has fruit in different stages of development. An everbearer with heavy yields of medium size fruit, it is recommended that the first bloom be removed to assure early plant size and larger fruit.
FORT LARAMIE Top
Everbearer
Introduced by the USDA Agriculture Research Service at Cheyenne, WY. Developed primarily for the north country. Everbearing and one of the sweetest tasting ever grown. Extremely hardy, heavy bearing with excellent vigor and abundant runner production. All season everbearing strawberry. Berries are large and bright scarlet red in color, have firm flesh, plenty of juice and a delightful sweet flavor. Self pollinating.
GAVIOTA- C205 Top
Springbearer, released from UC Davis in January 1997
The appropriate comparison cultivar for this selection is Camarosa, which appears to be replacing the Chandler cultivar in southern California and Santa Maria, and is also used to some extent in Watsonville/Salinas. C205 fulfills many of the objectives specified by the industry during the past five years. It has excellent fruit quality (especially flavor), a compact plant with a cull rate about half that of Camarosa, and it expresses several important components of environmental tolerance, notably rain tolerance and greater resistance to mildew, Anthracnose crown rot, and Verticillium. Camarosa is more adaptable to very early transplanting, and is likely to be more slightly productive than C205 in such systems. This selection should find acceptance in southern California as a quality fruit producer that requires later planting, broad acceptance in the Santa Maria area, and some acceptance in Watsonville/Salinas. C205 is very close to the day-neutral types in fruiting pattern and is a realistic alternative for growers currently planting Camarosa in Watsonville/Salinas. C205 has exceptional performance with summer planting and may be of use in the Central valley.
OGALLALA Top
Everbearer
Developed by USDA and University of Nebraska, crossing wild Rockie Mt. strawberries with garden varieties to combine the rare aromatic flavor of wild strawberries with the large size, heavy fruiting and everbearing habit of the best domestic varieties. Top quality large berries, dark red and firm. Superb for eating fresh and unusually fine for freezing and preserves. Very hardy; a great yielder. Fruit begins to ripen in late May or early June and just keeps on coming through September.
OSO GRANDE (US PATENT VARIETY #6578) C43 Top
Springbearer
Inventor, Voth.
This is a short-day variety, Released in 1987 by the University of California, Davis, CA. It is a cross between "Parker" and a hybrid between "Tioga and Pajaro". Interest in it is increasing in south and central coast counties, with the winter planting system preferred. Oso is a high-yielding variety, generally later in production than is Chandler. The fruit is larger than that of any other California cultivar and has a conic to wedge shape. Flavor is excellent , color is medium to dark red, and firmness and shipping qualities are very good.
PAJARO (US PATENT VARIETY #4538) Top
Springbearer
Inventory, Bringhurst, University of California
A short-day variety released in 1979, this is the predominant summer-planted variety in central California, accounting for 40 percent of central coast acreage and 15 percent of California acreage in 1989. Pajaro has commercially acceptable yields when established, using the summer planting system, but yields too little for economically successful winter plantings in California. This variety prefers mild temperatures for growing. Well established as the principle variety for winter-planting in Southern Italy and in Florida This variety is valuable for its exceptional and consistent quality, and for its extended fruiting pattern under central California's climatic conditions. The fruit is large, conical in shape, good flavored, and has an even moderately dark red color. Shipping qualities are exceptional, although it is susceptible to damage from rain. Using stored plants, Pajaro is planted between August 15 and September 5. Later plantings have reduced yield, but generally have larger fruit size. Early plantings are usually established where colder winters and warmer summers are expected in interior or semi-interior areas.
QUINAULT Top
Everbearer
Great tasting, heavy everbearing strawberry developed by Washington State University. It has been tested in 13 States and Canada with excellent performance record for size, taste and plant growth. It was found to be the most disease free everbearer . Berries up to 2" in diameter from June till frost. Self pollinating.
SEASCAPE (US PATENT VARIETY) Top
Everbearer
Inventor, Bringhurst, University of California.
Released by the University of CA, Davis in 1991, Seascape is one of the most productive everbearing varieties yet. Planting treatments that have worked well for Selva also do well for this variety. Because Seascape doesn't need much chill to set fruit, It's very well suited for warmer climates. Produces large berries with excellent flavor, over a long season, fruiting is concentrated in late spring with high yields into the fall. Each cluster produces one extra-large berry (called the king berry). This variety has good disease resistance but is somewhat susceptible to leaf rot
SELVA (US PATENT VARIETY #5266) Top
Everbearer
Inventor, Bringhurst, University of California
A day-neutral cultivar released in 1983, this variety is planted primarily in the central coastal counties, using both winter and summer systems. It accounted for 17 percent of the statewide acreage in 1989 plantings. High yielding, it has a typical day-neutral pattern for cyclical fruit production throughout spring, summer, and into fall. Commercial harvests have continued into December. Selva is exceptionally firm and has an acceptable appearance. Flavor is generally regarded as fair to poor, especially early in the season. Flavor is enhanced by allowing berries to fully ripen before picking. Selva also shows a low tolerance to two-spotted red spider mite. This problem can be sever when the plants are not properly conditioned with appropriate chilling treatments to stimulate vigor. This variety is susceptible to powdery mildew. Winter-planting recommendations for Selva call for harvest from high-elevation nurseries as late as is commercially feasible (the last 2 weeks of October) and planting after 2 to 4 weeks of supplemental cold storage, 33 F. Inadequate chilling results in plants with low vigor. Excessive storage can delay and reduce yields. Low-elevation Selva plants dug in mid-December and planted in January or later are now being grown commercially with mixed results. Most day-neutral varieties can be winter-planted with some flexibility, if special care is taken to provide optimum chilling. Summer planting of Selva is not recommended before September 10, with optimum performance often obtained by planting later in September. Large, very firm berries make this productive variety an excellent choice for both commercial and home gardeners. This variety is not well suited for northern locations above the Mason-Dixon Line due to its lack of winter hardiness. Intermediate plant size (12" tall). In Florida, is very early fruiting, usually producing some fruit in November, but the fresh fruit flavor of this cultivar is marginal.
SEQUOIA Top
Springbearer
SUNSET (UC PATENT VARIETY) CN-201 Top
Everbearer
Inventor, Bringhurst, University of California.
Introduced in 1993, developed by the University of CA breeding program with production potential in central and northern growing districts. Similar to the cultivar Selva with a consistently later pattern of production and stronger summer flowering response that either Seascape or Selva. Fruiting plants are more erect and very vigorous. and consistently larger fruit and greater yields. The fruit is glossy and red throughout , has a very good flavor, substantially better than Selva, but probably not equal to that of Seascape. Overall fruit quality for CN201 is better than Selva, for all characters except firmness which is similar to than of Seascape. Fruit is a flattened conic, sometimes heart-shaped. One caution here is that plants grown with insufficient vigor produce miss-shapen fruit in early spring.
CN201 is highly susceptible to powdery mildew, which will require close control and is less susceptible to two-spotted spider-mites than Selva.
Test results suggest that nursery and storage treatments that work well for Selva also work for CN201.
SWEET CHARLIE (IFAS FLORIDA #FL 85-4925) Top
Springbearer
Released in 1992 was named to honor Professor Charles M. Howard. Dr. Howard worked at the Dover Center from 1967 until his death in 1991. Sweet Charlie is complimentary to the principal cultivars now being grown in west central Florida. In taste tests conducted at he Gulf Coast Research & Education Center in Florida, the fruit was rated superior to that of Selva and Oso Grande for Flavor. The fruit had a higher concentration of sugars and vitamin C and lower acidity than fruit of Selva and Oso Grande. Summarizing the strengths of this variety, it is early fruiting, productive, resistant to anthracnose, and produces fruit with excellent flavor. Its major weakness is its susceptibility to Botrytis and Phomopsis fruit rot. The best way to minimize these rots is to apply protectant fungicides regularly, especially during periods of cloudy, humid conditions and warm weather. It may also be helpful to harvest every 2 or 3 days when daytime temperatures are in the 80's or night temperatures is the 60's. Other problems encountered include cat-faced fruit on the first "hand" of locally propagated plants; albino fruit on plants exposed to high levels of nitrogen fertilizer; cracking of fruit after a rain; and at times berries are produced on which the seeds rub off easily.
