Embodiment 1
[0029] like Figure 1-3 As shown, the present invention provides a kind of breeding method of powdery white strawberry, which is made up of the following steps:
[0030] Step 1. Plant the collected white wild strawberry germplasm resources in the wild strawberry germplasm resource garden. After resource evaluation, a single plant of yellow-haired strawberry with white fruit is selected as the male parent. It is collected from 10:00 to 16:00 on sunny days in April. Its stamens are naturally powdered in a test tube;
[0031] Step 2, with strawberry cultivar Hongyan as the female parent, on a sunny day in April, select robust, low-grade flower buds, peel off the petals, and remove the stamens inside;
[0032] Step 3. Use cotton dipped in germinative solution to gently smear on the female parent stigma obtained in step 2, dip the male parent pollen obtained in step 1 with a pollinating pen and contact the female parent stigma obtained in step 2, hang a label, and put on a transpa...
Embodiment 2
[0040] This example is a comparative example of Example 1, and the following is the actual operation data of the comparative example.
[0041]Taking the cultivated strawberry varieties Qianmiao No. 2 (red fruit) and Snow White (ginkgo) as contrast, the advantages of the new strawberry varieties with strong resistance, pink white and good quality bred by the present invention are displayed (see Table 1, Table 1, Table 1. Table 2, Table 3 and Table 4), Qianmi No. 2, Snow White and Qianmi No. 8 were planted in experimental greenhouses in late August for two consecutive years from 2020 to 2021, with a row spacing of 20cm × 25cm, and a total of 3 were planted according to the experimental design. A total of 90 strains were tested, with 10 strains per plot per strain, 3 replicates, and a total of 90 strains. The biological characteristics and fruit characters were compared with reference to "Strawberry Germplasm Description Specifications and Data Standards". The soluble solids were ...
