Method for obtaining male sterile plants of Chinese chives

Abstract

The invention relates to the technical field of genetic breeding of vegetables, in particular to a method for obtaining male sterile plants of Chinese chives. The Chinese chive seeds are radiated by adopting cobalt 60 rays with different dosages, so that the Chinese chive seeds are induced to be varied, and Chinese chive sterile plants are found to be generated in selfing line materials of different strains in a flowering phase investigation process. According to the method, the historical process that the sterile Chinese chive plants are completely naturally formed and accidentally discoveredin the past is broken through, the sterile plant rate of Chinese chive strains is greatly increased, and the occurrence probability of the sterile plant strains in the Chinese chive strains reaches 10.5%. The artificial generation of the Chinese chive sterile plant is a historical breakthrough in the Chinese chive breeding process, so that the formation of the Chinese chive sterile line is targeted, and the formation of the new Chinese chive variety is predictable.

Description

technical field [0001] The invention relates to the technical field of vegetable genetics and breeding, in particular to a method for obtaining male sterile plants of Chinese chives. Background technique [0002] Leek is a perennial herbaceous perennial plant of the Liliaceae Allium genus. It originated in China and has a cultivation history of more than 2,000 years. It is cultivated everywhere. [0003] There are abundant local varieties of leeks and newly bred varieties in China. If male sterile plants can be found among leek varieties, their clones can be established by tissue culture and rapid propagation technology, and then field ramets can be used for propagation and tissue culture and rapid propagation. The method to expand the sterile line population, and leeks can grow for 20 to 30 years under good cultivation conditions, so it is of practical significance to use male sterile line clones to produce a generation of hybrids. [0004] Plant male sterility manifests i...

Problems solved by technology

At present, Chinese chive breeders are paying more and more attention to the selection of male sterile lines of Chinese chives, but the sources of their male sterile lines of Chinese chives are all naturally produced in the field, and there is no great progress in the aspect of actively inducing sterile lines.
