USPP32800P3 - Strawberry plant named ‘Yakima’ - Google Patents

Abstract

The present invention provides a new and distinct strawberry variety designated as ‘Yakima’ (a.k.a. ‘109733’). ‘Yakima’ is distinguished by its higher percent of marketable fruit, conical fruit shape, thicker canopy and dark green foliage color.

Description

Latin name of the genus and species: Fragaria x ananassa.

Varietal denomination: ‘Yakima’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct short-day strawberry variety designated as ‘Yakima’ (a.k.a. ‘109733’).

‘Yakima’ (a.k.a. ‘109733’) is the result of a controlled-cross between a female parent cultivar designated (‘Aida’, a.k.a. ‘106734’,) an unpatented, proprietary strawberry plant variety made by the inventor and a male parent cultivar designated ‘Lili’ (a.k.a. ‘101983’ or ‘Lily’, U.S. Plant Pat. No. 25,849) and was first fruited in Watsonville, Calif. growing fields. Following selection and during testing, the plant was originally designated ‘109733’ and subsequently named ‘Yakima’.

The new variety was asexually reproduced via runners (stolons) by the inventor at Watsonville, Calif. Asexual propagules from the original source have been tested in Watsonville growing fields and to a limited extent, grower fields in high elevation. The properties of this variety were found to be transmissible by such asexual reproduction. This cultivar is stable and reproduces true to type in successive generations of asexual reproduction.

DESCRIPTION OF THE DRAWINGS

The accompanying color photographs depict various characteristics of the cultivar as nearly true as possible to make color reproductions.

SUMMARY OF THE INVENTION

This invention relates to a new and distinctive strawberry cultivar designated as ‘Yakima’. This cultivar is primarily adapted to the climate and growing conditions of the central coast of California. This region provides the necessary temperatures required for it to produce a strong vigorous plant and to remain in fruit production from March through October. The nearby Pacific Ocean provides the needed humidity and moderate day temperatures and evening chilling to maintain fruit quality for the production months.

‘Yakima’ (a.k.a. ‘109733’)

The following traits and photographs in combination distinguish the strawberry variety ‘Yakima’ from known strawberry varieties. In addition, the new cultivar was confirmed to be a unique strawberry germplasm when tested against the California Seed & Plant Lab, Inc. (Elverta, Calif.) database using Short Sequence Repeats (SSRs). Plants for the botanical measurements in the present application were grown as annuals. Any color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The botanical measurements listed in Table 1 were made and recorded during the month of June.

‘Yakima’ is distinguished from its paternal parent by the percent of marketable fruit (Table 2), for ‘Yakima’ percent marketable fruit is twenty percentile points greater than its paternal parent ‘Lili’ (U.S. Plant Pat. No. 25,849). ‘Yakima’ is distinguished from its maternal parent ‘Aida’ by the shape of its fruit. The fruit of ‘Yakima’ is mostly conical, different from the longer somewhat flat wedge shape of the fruit of its parent ‘Aida’. ‘Yakima’ is similar to the strawberry plant named ‘Monterey’ (U.S. Plant Pat. No. 19,767), but possesses several distinguishing traits from Monterey. ‘Yakima’ is distinguished from ‘Monterey’ by the thicker canopy of ‘Yakima’ and dark green foliage color of ‘Yakima’.
