A method for accelerating the process of cultivating new varieties of Chinese chives

Abstract

The invention relates to a method for accelerating the cultivating process of new varieties of Chinese chives. The method comprises the steps that 1, F3'-F5' generation individual plant inflorescencegood in property is selected and divided into to parts, wherein the An inflorescence is subjected to inflorescence disc tissue culture, and the Bn inflorescence is bagged and selfed to observe whetheroffspring characteristics are separated or not; 2, An inflorescence disc tissue culture is conducted to form tissue culture and rapid propagation population; 3, the Bn inflorescence is bagged for selfing, and superior individual plants of offspring are screened and separated; 4, the tissue culture scale is enlarged through rapid propagation, and excellent plant population is built; 5, seedling separating, seedling hardening and seedling strengthening are conducted; 6, field planting is conducted in a breeding field, and growth management is conducted, seeds are harvested after manuring, and then the cultivating process of the new varieties of the Chinese chives can be completed. According to the method for accelerating the cultivating process of the new varieties of the Chinese chives, homozygous plants can be screened out rapidly through tissue culture, bagging and slefing, Chinese chive growth period shortening and the like in the Chinese chive breeding process, the growth period ofthe Chinese chives is shortened, the breeding time is shorted, the Chinese chive breeding process is accelerated, and the Chinese chive breeding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vegetable cultivation, in particular to a method for accelerating the cultivation process of new leek varieties. Background technique [0002] Chives are native to China and have a long history of cultivation. They are one of the special Chinese dishes that integrate vegetables, spices, and health care. They are also one of the main vegetables that Chinese urban and rural residents like to eat. It takes a long time to build an excellent germplasm population in the field, the purity is low, and trait separation is very easy to occur. The process of breeding Chinese chives from excellent single plants to strains and strains is not only time-consuming, but also the purity is difficult to guarantee. This not only restricts the development of new chives The progress of variety selection and breeding has also restricted the rapid breeding and promotion of new varieties. [0003] It takes 12-15 years for the co...

Problems solved by technology

The use of tissue culture technology can preserve the male sterile line of Chinese chives, but the advanced rapid propagation technology is out of touch with the breeding practice of Chinese chives and has not played its due role

Due to the long breeding cycle and the long time for the establishment of an excellent population size group in the existing conventional breeding technology of Chinese chives, not only the breeding efficiency of Chinese chives is high and the cost is high, but also most of the new Chinese chive varieties used in production to speed up breeding are mixed-line varieties, and pure-line varieties are very rare. few

This not only reduces the quality of breeding, but also restricts the full play of the excellent germplasm potential of new varieties of Chinese chives, so there is an urgent need for a method to speed up the process of cultivating new varieties of Chinese chives
