Abstract

The invention discloses an indoor culture method of seedling seed potatoes. The method is characterized in that seedling seeds harvested in the current year are subjected to dormancy processing and germination acceleration, and seedling seed sowing culture is performed in a culture room to produce the seedling seed potatoes. The method mainly includes: preparing substrates, preparing seedling culture plates, breaking the dormancy period of the seedling seeds, and performing germination acceleration, sowing, management and harvesting. The method has the advantages that the seedling seeds harvested in the current year are used to produce the seedling seed potatoes in the current year, the seed culture time is shortened by more than one year as compared with the existing seed culture technology, and seed culture efficiency is increased; the seedling seed potatoes are directly produced in the seedling culture plates, transplanting labor is reduced, and seed potato production land is saved; the seed potatoes are directly cultured in the seedling culture plates, and a seedling culture effect is prevented from being affected by seedling culture genotype loss caused by seedling deaths during transplantation; soil diseases and pests caused by a convention culture manner are avoided; the substrates are local natural-resource pine needle humus soil, the rich nutrition of the humus soil is provided for the growth of plants, fertilizing is not needed, and the substrates are easy in material obtaining and low in cost.

Description

technical field [0001] The invention relates to a method for indoor cultivating seed potatoes of potatoes, belonging to the technical field of potato planting. Background technique [0002] 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 generation to generation through tuber vegetative propagation. Due to the low seed setting rate of potato hybrids, the probability of obtaining hybrid seeds is small, and a large amount of hybridization work is required, and the probability of a certain hybrid offspring in the com...
