Quick efficient breeding method of detoxicated small seed potato

Abstract

The invention relates to a quick and efficient breeding method of a virus-free small potato seed, which belongs to the technical field of seed-breeding of crops. The breeding method comprises the following steps: (1) preparation of facilities; (2) preparation of matrix; (3) preparation of potato seeds: 5-20g of original minituber seeds of the virus-free potatoes are germinated to obtain buds, then the buds are refined one month before sowing; (4) sowing of the potato seeds; (5) seedling growing of the potato seeds; (6) collection of the original small potato seeds: the seeds can be collected for 4-5 times in the whole growing period, over 10g of an individual plant of the minitubers can produce over 59 potato seeds and produce 413,000 small potato seeds per mu, and the propagation coefficient is 1:91.7, which reaches or approximates the propagation coefficient of the conventional seed crops. The breeding method is suitable for breeding original small potato seeds from the original virus-free small potato seeds (minitubers), simplifies the fine virus-free potato seed breeding system, promotes the popularization and application of the virus-free potatoes, and can be popularized and applied to potato production.

Description

technical field The invention relates to the technical field of crop breeding, in particular to a rapid and high-efficiency breeding method for producing small original seed potatoes from original original seed miniature tubers of virus-free potatoes. Background technique Potato detoxification technology and the production technology of detoxification test-tube seedlings, test-tube miniature tubers, and miniature tubers have become increasingly mature, and have formed a certain industrial scale at home and abroad. At present, domestic detoxification original species (miniature tubers) The factory production has reached the degree of large-scale commercialization, the production cost can be controlled at 0.1 yuan / grain (8-10g), and the sales price is 0.3-0.5 yuan / grain. Due to the small reproductive coefficient of potatoes, in the existing breeding system of virus-free potato varieties, the original seed (miniature potato) in the second-season cropping area generally needs to...

Problems solved by technology

The purpose of the present invention is to aim at the existing virus-free potato in the seed potato breeding process, the ubiquitous breeding generation is many, the effect of increasing yield is poor, the reproduction coefficient is low, the cost of using seeds is high and the cost of equipment and materials existing in the aeroponic method is high, The management technology is strong, and it is only suitable for the production of the original seed (miniature potato) and other defects. A simple material, simple management, and low cost is proposed, which is not only suitable for the production of the original seed (miniature potato), but also suitable for the production of the original seed. Potatoes, a method for rapid and efficient breeding of virus-free potatoes with short generations in the open field
