Technical Field
The invention relates to the technical field of potato planting, in particular to a quick and effective germination accelerating method for potato seedling seeds.
Background
The potato belongs to selfing crops and asexual propagation crops, and the crossbreeding is different from other selfing crops. The potato varieties are the first generation asexual propagation lines of the backcross of crossbreeds, and the characteristics of the potato varieties are stabilized by asexual propagation after the crossbreeds are not separated into pure lines. Therefore, potato varieties are all heterozygotes, and have extremely complex heterogeneity in genetics. The hybrid or selfing progeny of potato are all separated in a complex way, the variation character generated by sexual hybridization shows various types in the hybrid generation of seedling, once a single plant of excellent seedling is selected from the hybrid or selfing progeny, the excellent character can be maintained by asexual propagation to form a new variety, and the potato seedling harvested in the current year has long dormancy period, poor germination potential and extremely irregular seedling emergence, the germination rate is only 30-60 percent, and the potato seedling is generally used in every other year.
The potato seedling seeds have two utilization ways in production: firstly, the breeding of the new potato variety is carried out by a conventional breeding method, namely, seedling seeds are obtained by hybridization between potato varieties and between seeds, the seedling seeds are cultured into seedlings through natural dormancy, single plants are selected at the current generation of the seedlings, and the variety is cultured after 8-10 years; secondly, the hybrid seedling seeds with excellent combination are directly used for producing the potato field, and the heterosis of the first filial generation is utilized for production and application, so that the problems of less seed consumption, low seed consumption cost, small volume, convenient transportation and reduction of plant diseases and insect pests are solved.
