Potato hybrid seedling seed bean coating direct seeding method

Abstract

The invention discloses a potato hybrid seedling seed bean coating direct seeding method. Hybridized potato seedling seeds are subjected to germination accelerating treatment and then implanted into cooked soybeans, and the seeds are sowed into a greenhouse to produce seedling seed potatoes for individual plant identification. According to the method, seed bean coatings are adopted, fine potato hybrid seedling seeds are enlarged, single grain direct seeding is facilitated, water and nutrients of the soybeans can be used by seedling seed emergence and growth, and the problem of weak germinationability of the fine potato hybrid seedling seeds is solved. Moreover, the seedling seed potatoes are directly harvested by direct seeding, and the problems of excellent variation type loss and the like caused by large labor amount and low seedling survival rate are solved.

Description

technical field [0001] The invention relates to a method for sowing hybrid potato seeds, in particular to a method for direct-seeding potato hybrid seeds coated with beans. Background technique [0002] Potato hybrid seeds are small, with a thousand-grain weight of only about 0.5 grams and weak germination. Therefore, creating an excellent environment suitable for the germination and growth of hybrid seeds is very critical for improving the seedling rate. [0003] The current potato breeding method in my country is mainly to obtain seed seeds through sexual hybridization or selfing. After the eye-rest period of the seed seeds has passed, the seedlings are accelerated and transplanted, and high-quality, high-yielding new potato varieties are selected from the offspring of the seedling clones. In conventional potato breeding, variation occurs in the first generation of hybrids, that is, the seedling generation of hybrids, and the variable traits are fixed and passed on from g...

AI Technical Summary

Problems solved by technology

The method adopts bean-wrapped seed coating, which not only makes the small potato hybrid seeds larger, which is beneficial to single-grain direct seeding, but also the moisture and nutrition contained in soybeans can be used for the emergence and growth of seed seeds, which solves the problem of the potato hybrid seeds being small and germinating. The problem of weak force; and the direct harvesting of seed potatoes by live broadcast solves the problems of large amount of labor and low seedling rate in the transplanting of seedlings, which cause the loss of good variation types.
