Method for breeding basic seeds of potato by field transplanting of tissue culture seedlings on low-latitude plateau

Abstract

The invention discloses a method for breeding basic seeds of potato by field transplanting of tissue culture seedlings on low-latitude plateau; the method comprises the steps of building a seedling raising pond, scientifically preparing a seedling culture medium, planting tissue culture seedlings, managing pesticides and fertilizers for raising the tissue culture seedlings, transplanting the tissue culture seedlings to a field, managing the field, preventing and controlling late blight, harvesting basic seeds and the like; According to the method, the seedling culture medium is scientificallyand reasonably prepared, and the growth conditions for seedling raising are scientifically and reasonably controlled, in combination with the growth characteristics of tissue culture seedlings of potato; transplanting planting with the medium is adopted, technical conditions such as planting time, seedling transplanting time, planting modes and the like are strictly controlled, and therefore, thesurvival rate of the seedlings is effectively increased, the growth vigor is improved, the defect and problem is solved that pre-basic seeds with tissue culture seedlings are bred before basic seeds are bred with the pre-basic seeds or that seed potatoes are bred in the field directly through tissue culture seedlings, the breeding efficiency of potato seeds is effectively improved, and the labor intensity, facility construction investment and production cost are reduced; and the method is a practical breeding technology of seed potatoes with simple operation procedure, labor saving and labor saving, and is suitable for popularization and application in high-altitude southwest mountainous areas.

Description

technical field

[0001] The invention belongs to the technical field of potato seed potato breeding, and in particular relates to a method for transplanting and breeding original potato seedlings in low-latitude plateau fields; Background technique

[0002] The potato industry has become a pillar industry in the mountain planting industry in Yunnan Province, and it is one of the main ways for farmers in mountainous areas to increase their income and increase agricultural efficiency; due to the arid and barren soil in mountainous areas, extensive farming management, single and backward cultivation techniques, and potatoes are asexually propagated crops, During the planting process, virus infection causes seed degeneration, which seriously affects the increase in potato yield. The application of virus-free seed potatoes contributes 30 to 50% to potato planting. Breeding high-quality virus-free seed potatoes is the key to potato production. An important link in the production of...
