The invention relates to a white large-fruited strawberry
germplasm innovation method and belongs to the technical field of
plant breeding. A cultivated variety 'Toyonoka' of large-fruited strawberries having sweet and sour
flavor are used as a female parent, a wild white-fruited yellow-hairy strawberry variety 'white bubble' originally from Yunnan in our country is used as a male parent to perform hybridization, the obtained
hybrid generation undergoes
colchicine processing and directional selections, such as fruit characteristics and features, and the novel white large-fruited strawberry
germplasm is bred. By adopting the novel
germplasm 'FB02', obtained fruits are conical, and the whole fruits are uniform and regular. The average
fruit weight is about 13.4 g, the longitudinal
diameter of each fruit is 3.5 cm, and the
transverse diameter of each fruit is 2.7 cm. The fruits have white surfaces and low glossiness. Fruit pulp and cores are white. The sweet and sour
flavor is agreeable, the fragrance is heavy, and the fruits have rich peach fragrance and moderate
hardness. The growth vigor of plants is moderately strong,
plant shapes are semi-upright, and the
plant height is about 30 cm. Leaves are subround, large and thick, and leaf color is green. Flowers are moderately large, and the crown
diameter is about 2.8 cm. The plants are similar to the Toyonoka in resistance, are quite resistant to anthracnose and can be used as a
parent material for white strawberry breeding.
