Abstract

The invention discloses a production method of a homozygous material for the breeding of a common head cabbage with wax-free bright leaves. The method comprises following steps: taking a common head cabbage mutant material (429MT) having a wax-free bright leaf single gene (a recessive inheritance gene) as the female parent and a wax containing excellent homozygous common head cabbage material as the male parent to carry out hybridization to obtain first generation F1; making F1 carry out selfing to obtain F2; choosing excellent strains with a wax-free bright leaf character from F2 generation as seeds; and carrying out free spore cultivation in next spring during the blossoming period to obtain a homozygous double haploid wax-free bright leaf material. The application of the wax-free brightleft mutant material is promoted; the production of the novel wax-free bright leaf breeding material is accelerated, and the cultivation process of high quality common head cabbage is shortened.

Description

technical field [0001] The invention belongs to the technical field of cabbage breeding, and in particular relates to a method for creating a homozygous material for head cabbage breeding without wax powder and bright leaves. Background technique [0002] Heading cabbage, also known as cabbage, cabbage, cabbage, etc., belongs to the Brassica genus Brassica species of Brassicaceae. It has rich nutritional value, strong resistance, wide adaptability, easy cultivation, and high yield. It is widely planted all over the world. One of the main vegetable crops. The amount of wax powder on the surface of the cabbage plant is an important indicator to determine the quality of the product. Products with less wax powder have bright green leaf color, good sense and quality, and are welcomed by consumers. Breeding cabbage varieties with green bulbs is one of the main breeding goals of breeders. In the Yangtze River Basin and the south of China, beef heart (sharp ball) type cabbage has...
