[0003] There are very few pink-white strawberries planted in production and cultivation. First, the planting technology requirements are high. The existing pink-white strawberry varieties have problems such as late fruiting period, poor disease resistance, fragile seedlings, and difficult planting management. Second, pink-white strawberries There are few varieties, and the pink and white strawberry varieties are rare, mainly because the breeding process is difficult.

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 ...

Abstract
The invention discloses a breeding method and application of pink white strawberries, and relates to the technical field of plant breeding, and the breeding method comprises the following steps: step 1, taking wild ginkgo strawberries as male parents, and collecting pollen; step 2, taking a pineapple and strawberry cultivated variety as a female parent, and emasculating flower buds; 3, after pollination of the female parent, sleeving the female parent with a transparent fruit bag made of pure wood pulp paper, and tightening the bag opening; step 4, when the hybrid fruits in the step 3 are fully ripe, picking the strawberry fruits, and treating the strawberry fruits; 5, sowing the treated seeds, transplanting, doubling, propagating, planting and screening to obtain superior plants; and step 6, hybridizing the excellent plant screened in the step 5 as a male parent with a pineapple strawberry cultivated variety as a female parent, collecting seeds, sowing, transplanting, and screening to obtain a new variety with excellent quality and white fruit flour. According to the method disclosed by the invention, the advantages of strong fragrance and white fruit surface of wild strawberries are combined with the advantages of large fruit and high yield of cultivated strawberry varieties, and the new pink-white strawberry variety with strong fragrance, white fruit surface and large fruits is bred.
Description
technical field [0001] The invention relates to the technical field of plant breeding, in particular to a breeding method for pink-white strawberries and application thereof. Background technique [0002] Strawberry is one of the main fruit tree species in China. It belongs to the Rosaceae Strawberry is a perennial evergreen herb. The strawberry fruit is beautiful in color, unique in flavor and rich in nutrition. It is known as the "Queen of Fruits" and has high nutritional and dietary value. It is deeply loved by people. In traditional strawberry production and cultivation, red fruits are mainly used, and there are few pink-white fruits. In addition to the original nutrition and flavor of red strawberries, pink-white strawberries have white or slightly pink fruit surface, white pulp and strong fragrance. , the water is sufficient, and some also have the flavor of peach. Therefore, due to its unique taste and reddish appearance, pink and white strawberries have been loved by...
