Title: Day-Neutral vs. Short-Day Strawberry Breeding Advantages and Exploitation Potential
Author: R.S. Bringhurst
Day-neutral strawberry cultivars were bred by backcrossing hvbrids of Fragaria virginiana glauca from the Wasatch Mountains near Salt Lake City, Utah, with California short-day cultivars. The process is simple because the day-neutral trial may be handled as a simple dominant. Large fruit size and commerciallv acceptable quality was restored within 3 backcross generations. In relatively warm winter south coastal sites, the dayneutrals can be brought into significant production in November, December and January by summer planting stored plants in early August. Fruit production starts about 3 months after planting. This contrasts with the short-day types which begin fruiting in February at the earliest in southern California. Similar day-neutral selections have been made to bear consistently throughout the late summer and fall in central coastal California, by planting them at least 3 months ahead of the desired time for starting fruit production. Short-day cultivars are undependable during the late summer and fall although they always produce some fruit. With the introduction of day-neutrals, California strawberry growers will have the option of producing fresh strawberries every month of the year using them to complement the production patterns of existing short-day types.
