Embodiment

[0021] Embodiment: Breeding of Purple Yellow Leaf Rapeseed No. 1

[0022] Male parent: purple-red leaves of Brassica napus "Purple Gin": a Brassica napus strain bred by Guizhou Oil Plant Research Institute through interspecific hybridization. Control of genes. See Tongqiang, W., H. Zesu, T. Zhuping, Y. Xiaoron G, D. Wendong and S. Mingbo (2007). Material breeding, heredity and utilization of purple-red leaf marker character in Brassica napus L.. Proceedings of the 12th International Rapeseed Conference, Wuhan, China, March 26-30, 2007. (photo as figure 1 shown)

[0023] Female parent: Cytoplasmic male sterile line of Brassica napus with chlorotic heart leaves, Ogu CMS. (See figure 2 shown).

[0024] In the first ten days of September, live broadcasting was used to plant purple-red-leaf cabbage-type rape "Purple Glycerin" and cabbage-type radish cytoplasmic sterile lines with chlorotic heart leaves. Next year spring, adopt the non-woven bag of wide 20cm, long 50cm to ba...

Abstract

The invention discloses a breeding method of an ornamental purple-yellow-leaf rape line. According to the method, a cabbage type rape radish cytoplasmic male sterile line with lack of green core leaves is used as a female parent, a purple-red leaf cabbage type rape line is used as a male parent, and hybridization is conducted to obtain a first-filial generation; and the first-filial generation isbackcrossed with the purple-red leaf cabbage type rape line so as to obtain rape of the ornamental purple-yellow-leaf rape line. The ornamental purple-yellow-leaf rape line is a novel ornamental oilseed rape having yellow core leaves and other purple-red leaves and obviously different from the leaf colors of other rapes. The rape can be used in tourist attractions, parks, urban squares, urban roadgreening and other tourist, sightseeing and leisure places; the rape has high ornamental value as people can enjoy the sight of the leaves of the rape in a seedling stage and the flowers of the rapein a flowering stage; and an ornamental period of the rape is six months or more.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for breeding a purple-yellow-leaf ornamental rape strain. Background technique [0002] Rapeseed is one of the main oil crops in the world. The types of rape currently used in production mainly include Brassica napus L., Brassica juncea L. and Brassica campestris L.. With the development of rapeseed quality breeding, especially the breeding and promotion of double-low (low erucic acid, low glucosinolate) rapeseed varieties, the acquisition of high-quality rapeseed oil and feed protein has become the most important purpose of rapeseed production, and promotes the world. The development and progress of rapeseed production. [0003] The function of rape is not limited to this. In recent years, with the vigorous development of the tourism industry, the tourism function of rape has been continuously highlighted. In the spring when everything is recovering, a field of rapeseed...
