A kind of method for obtaining leek male sterile plant

Abstract

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. By using different doses of cobalt 60 rays to irradiate the seeds of Chinese chives, the seeds of Chinese chives are induced to mutate. During the investigation of the flowering period, it was found that sterile plants of Chinese chives were produced in the inbred lines of different strains. The invention breaks the historical process that the sterile leeks are completely formed naturally and discovered by chance in the past, greatly increases the sterile plant rate of the leek strains, and the occurrence probability of the sterile strains in the leek strains reaches 10.5%. The artificial generation of Chinese chive sterile strains is a historic breakthrough in the breeding process of Chinese chives, which makes the formation of male sterile lines of Chinese chives targeted and the formation of new Chinese chive varieties predictable.

Description

technical field [0001] The invention relates to the technical field of vegetable genetics and breeding, in particular to a method for producing male sterile plants in the field through seed radiation induction. 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.

AI Technical Summary

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.
