  • Patent number: PP7171
    Abstract: A new and distinct spring bearing variety of strawberry plant, characterized by its ability to produce large, glossy, dark crown crop berries during the early spring when given adequate chilling before being winter planted in southern California.It is distinguished by its consistently good shaped fruit that reflect an abundance of pollen production and uniformly fertilized pistil and achenes that develop. This crown crop fruit with its large calyx is borne on long thick pedicils. The plant is considered dark, and is vigorous only if given adequate chilling before being planted. This variety has the ability to continue cropping even in the summer, after the picking for the fresh market has been terminated.

  • Patent number: PP7522
    Abstract: A new and distinct everbearing variety of strawberry characterized by its low growing plant that responds to nitrogen fertilizer and cold storage chilling and is considered a high chilling type.The variety is also distinguished by its ability to initiate a large main crop even late in the fall and winter following a summer planting. The fruit that is produced is of good quality and is easily accessible to pickers.

  • Patent number: PP8649
    Abstract: `UV601` is a spring bearing variety which produces attractive dark colored crown and main crop fruit from April to October when grown as a winter planted variety on the coast of central California and when adequately chilled before and after planting. The crop is early in maturing and in Florida ripens in December. `UV601` has consistently firm skin and flesh, a large attractive calyx and good strawberry flavor. The variety is further characterized by its cordate-shaped leaflet serrations, acute at the apex, its purpling of leaf parts after the crown crop and its large calyx.

  • Patent number: PP8745
    Abstract: `V258` is a spring bearing variety of strawberry plant characterized by its ability to produce a strong plant, which remains in production consistently from April to October in the central coastal area of California if given adequate chilling before and after being winter planted.The variety is particularly distinguished by its large, light colored, multi-crowned plant, its large crown and main crop berries, with light colored surface and firm flesh and by its consistently high quality strawberry flavor.

  • Patent number: PP8970
    Abstract: This invention relates to a new distinct short day winter-planted variety of strawberry plant named `X13`. The plant of this variety is distinguished by its dark, glossy foliage and its ability to initiate flowers from early spring to late fall in the Central Coast of California and spring and summer in southern California. The fruit is distinguished by its consistently high flavor, long shelf life, good fruit color inside and out and glossy, smooth surface. Its fruit is adapted to being processed for the freezer trade, especially for the Individual Quck Frozen berry demand, as well as for the fresh market.

  • Patent number: PP9130
    Abstract: `Balboa` is a spring bearing variety which produces smooth glossy, attractive, full colored fruit, both on the surface and in the juicy flesh and has a very good flavor.The crop is medium early in southern and central California and has the ability to produce a high volume of fruit in March, April and May in southern California, if the transplant is given proper chilling before being planted.If grown in central California, the plants have the ability to continue production in the summer and fall. The plant is characterized by being medium dark and becoming large by summer. When vigorous, it is common to have one or more leaves per plant produce four leaflets per leaf instead of the normal three.The fruit of the plant is also characterized by a large, dark calyx on primary berries which often produce a double row of serrated sepals. These sepals often become curled and are held irregularly, with narrow sepals, when present, held on the row away from the fruit, not next to the fruit.

  • Patent number: PP10221
    Abstract: This invention relates to a new and distinct variety of strawberry plant named `Coronado`, botanically identified as Fragaria.times.ananassa. The closest known variety is `Balboa`. The new variety is partially everbearing. The new variety is distinguished from `Balboa` by its globose plant habit, medium plant density, flat to cupped terminal leaflet profile, outwardly pointed petiole hairs, the inflorescence is held level to above the leaves, and the calyx is larger than the corolla. The harvest yield before April 1 of `Coronado` is about 4.4 times greater than for `Balboa` for the same period. The main crop of `Coronado` is approximately one week before that of `Balboa`. The PGI isozyme banding pattern for `Coronado` is A2, while that for `Balboa` is A1. The LAP banding pattern for both `Coronado` and `Balboa` is B3. The PGM banding pattern for `Coronado` is C4, while that for `Balboa` is C2.

  • Patent number: PP10534
    Abstract: This invention relates to a new and distinct variety of strawberry plant named `Lido`, botanically identified as Fragaria .times. ananassa. The closest known variety is `Swede`. The new variety is partially everbearing. The new variety is distinguished from `Swede` by its glossier upper leaf surface, dense petiole pubescence and longer petiole pubescence. The cull rate for `Lido` was 42% of that for `Swede`. Following prolonged storage, the percent fruit that had rotted for `Lido` was about 57% of that for `Swede`. The reaction to disease was similar between `Lido` and `Swede`, but `Lido` is moderately resistant to Botrytis fruit rot, whereas `Swede` is susceptible. The PGI isozyme banding pattern for `Lido`, is A3, while that for, `Swede` is A1. The LAP and PGM banding patterns are B3 and C2, respectively, for both `Lido` and `Swede`.

  • Patent number: PP10642
    Abstract: This invention relates to a new and distinct variety of strawberry named `San Miguel`. The variety is similar in appearance to `Camarosa`. The variety is characterized from `Camarosa` by its medium plant vigor, medium green length to width ratio of the terminal leaflet, the inflorescence is positioned above the leaves, conical to almost cylindrical fruit shape, red skin color, and fruit flesh that is red and firm. `San Miguel` possesses unusually long pedicels.
