Embodiment Construction

[0014] A high-efficiency and high-quality breeding method for potato seed potatoes. The method is to breed test-tube tubers under tissue culture conditions, and use the temperature advantage of the potato winter-cropping area in Yunnan Province, China. The original potato seed, and then go to the potato autumn cropping area in Yunnan Province to obtain the first-generation seed potato of the original seed and the second-generation seed potato of the original seed produced in high-altitude areas. The specific methods are as follows:

[0015] (1) In May of the first year, the test-tube plantlets were obtained by tissue culture cut-off rapid propagation method, and then after culturing for one month, high-sugar medium was added to the culture bottle in the ultra-clean workbench, and cultured in the dark to induce fruiting test tube potato;

[0016] (2) In November of the same year, test-tube potatoes were planted in greenhouses in the potato winter cropping area of ​​Yunnan Provi...

Abstract

The invention provides a high-efficiency high-quality breeding method for planting potato. According to the method of the invention, potato microtuber is bred in a tissue culturing condition. Firstly, an elite potato is obtained from a potato winter-culturing area in Yunnan province of China through planting the potato microtuber in a greenhouse. Then elite first-generation potato microtubers and high-altitude region growing elite second-generation microtubers are successively obtained in a potato autumn-culturing area in the Yunnan province of China. According to the method of the invention, the elite potato is produced by means of the potato microtuber and has advantages of high seedling rate, large number of produced potatoes, large size and high output. Furthermore labor saving and easy operation are realized in planting the potato microtuber. The method further has advantages of high convenience in management, and standard production.

Description

technical field [0001] The invention belongs to the technical field of seed potato breeding. Background technique [0002] Potatoes are asexually propagated crops, and tubers are usually used as seeds. Many diseases are easily passed on from generation to generation and expand damage through tubers. Sustainable development and quality improvement of potato industry. [0003] It usually takes 4-5 years for seed potato breeding in my country. The technical process of potato breeding is: test-tube seedling → original potato seed → first generation of original seed → second generation of original seed. During the whole breeding process, test-tube seedlings are used for breeding, and the survival rate is low. , and the planting is difficult and difficult to manage, resulting in low yield and high cost of the original seed. Contents of the invention [0004] The purpose of the present invention is to solve the existing problems of long seed potato breeding cycle, high cost, low...
