Embodiment Construction

[0037] The raw materials and auxiliary materials used in the present invention are all materials that can be publicly sold on the market.

[0038] a. Rootstock cultivation and selection

[0039] Generally grow seedlings in the greenhouse, soak the physalis seeds in warm water at 45°C, or soak them in 0.01% potassium permanganate solution for 10 minutes to prevent the seeds from carrying viruses and other germs; then soak them in clean water for 12 hours, remove them, and spread them evenly on wet towels First, roll the towel into a roll and put it in a 30°C artificial climate box to accelerate germination; after 40%-50% of the seeds are white, they can be sown;

[0040] The treated seeds are sown in seedling trays with a substrate of peat soil, covered with 3mm-5mm of soil. Cover with a layer of 75% sunshade net, spray water with a sprayer every day to maintain the humidity of the substrate, keep it at 20°C-25°C during the day, and 10°C-15°C at night;

[0041] Thin out seedl...

Abstract

The invention belongs to the technical field of potato breeding, and particularly relates to a method for solving infertility of potato varieties serving as hybrid female parents. The method includes the steps of stock selection and cultivation, scion cultivation, grafting, management after grafting, hybrid pollination and common mulberry seed harvesting. A potato serving as a scion and a winter cherry serving as a stock are grafted into a whole, a huge root system of the winter cherry provides more sufficient nutrients for an overground part by cutting off nutrient consumption needed by tuber growth of an underground part of the potato, a reproductive organ of the potato acquires enough nutrient supply, normal growth and development of the reproductive organ are promoted, normal fructification after pollination is achieved, and the problem of infertility of the potato varieties serving as the hybrid female parents for a long time is solved.

Description

technical field [0001] The invention relates to the technical field of potato breeding, in particular to a method for solving the infertility of potato varieties used as hybrid female parents. Background technique [0002] Potatoes are native to the Andes in South America. Potato germplasm resources in my country are limited, but some potato resources still cannot bloom and bear fruit normally: for example, Kexin No. 1, the potato variety with the largest planting area in the country, has concentrated tubers and a high rate of large tubers. , high yield and stable yield, but the pollen is infertile, the pistil is aborted, it cannot be naturally fruited, and as a hybrid parent, that is, the stigma cannot grow normally and produce seeds after pollination. Therefore, the above-mentioned excellent potato resources cannot be used as hybrid parents, which limits the genetic basis of potato hybrid breeding. [0003] Potato budding to flowering period is the peak period for the form...
