Embodiment 1

[0024] 1. Cultivate light yellow flower No. 1

[0025] (1) Synthesis of Purple Brassica napus strains by interspecific hybridization of Brassica oleracea and Chinese cabbage

[0026] Purple leaf cabbage variety Zixin and Chinese cabbage variety Huang 75-28 were planted in the field in autumn. In the spring of the following year, after the cabbage and Chinese cabbage bloom, the cabbage flower buds are manually peeled off with the cabbage as the female parent, the anthers are removed, and the pollen of the Chinese cabbage is pollinated on the stigma of the cabbage after the buds are peeled off. 7-10 days after pollination, remove the ovaries obtained by interspecific hybridization, and sterilize them with 30 ml 84 disinfectant for 10 minutes, and shake and mix repeatedly during this period. Sterilized ovary transferred to solid B 5 Place it on the culture medium for 16 hours of light and cultivate in a culture room at 25° C. until the ovary grows and matures, and harvest the ...

Abstract

The invention discloses a breeding method for a new cabbage type rape line, and belongs to the field of a plant new variety breeding method. According to the breeding method disclosed by the invention, a cabbage type rape line is synthesized by interspecific hybridization of cabbages and Chinese cabbages, and the synthesized cabbage type rape line is subjected to quality genetic improvement of economical characters, erucic acid and glucosinolate so as to breed one new ornamental rape line with a bran-new petal color and a bran-new stalk color; the new cabbage type rape line meets both requirements for ornamental value and oil use, and brings greater economic benefits and social benefits for rape production and the tour and sightseeing industry.

Description

technical field [0001] The invention relates to the breeding technology of new strains of Brassica napus, and belongs to the field of new plant variety breeding methods.
