Embodiment 1

[0043] The method for breeding forage rapeseed by interspecific hybridization provided in this embodiment includes:

[0044] 1. Determine the hybridization method according to the type and richness of the breeding material. Prepare a series of hybrid combinations.

[0045] A Brassica napus male sterile line of the radish cytoplasmic sterile type that meets the following criteria was selected as the female parent: vigorous growth, high biological yield, lodging resistance, disease resistance, low glucosinolate content, strong lodging resistance, relatively Large number of effective branches, relatively consistent maturity and easy mechanical harvesting. The ones selected as female parents were: Brassica napus male sterile lines 11A, 13A, 34A, 37A, 39A, 44A and 47A.

[0046] The cabbage that meets the following criteria is selected as the male parent: vigorous growth, high biological yield, high combining ability and good taste. The selected male parents are: Xishui Rapeseed ...

Embodiment 2

[0063] This embodiment provides a method for using the forage rapeseed bred in Example 1, which includes: directly sowing the forage rapeseed bred above, harvesting when the flowers fade, and using it as silage.

[0064] Of course, it should be noted that, in other embodiments, forage rapeseed seeds can also be planted in orchards, beside roads, and around yards for direct consumption by livestock.

[0065] To sum up, the present invention uses the characteristics of heterotrophic vigor and strong stress resistance among Brassica varieties to breed rapeseed varieties that can be used as special types for feeding, so as to make up for the gaps in the existing rapeseed for feeding, and Rapeseed rape for breeding can be bred by the method and has the characteristics of high biological yield, strong adaptability, fast growth, good taste and high nutritional value.

Abstract

The invention discloses a method for breeding forage rape by using interspecific hybridization and a use method and relates to the field of genetic breeding. The method for breeding the forage rape by using the interspecific hybridization, disclosed by the invention, is characterized in that rape is used as a female parent and is subjected to the interspecific hybridization with a brassica plant variety as a male parent; the forage rape is bred from F1; and in addition, the variety type of the male parent is different from that of the female parent. According to the method, a special forage rape variety can be bred by using the advantages of hybrid trophosomes of brassica varieties and the characteristics of high resistance and the like, and the defects of the conventional forage rape are made up; and besides, the forage rape bred by the method has the characteristics of high biological yield, high adaptability, high growth speed, good mouthfeel, high nutritive value and the like.

Description

technical field [0001] The invention relates to the field of genetic breeding, in particular to a method for breeding forage rape by interspecific hybridization and a use method. Background technique [0002] At present, forage rapeseed is mainly selected from seed rapeseed varieties with large biomass and used as forage rapeseed, and certain effects have been achieved. However, there are multiple targets for breeding at the same time, which disperses the energy of breeding; and there is still room for improvement in biological yield and other aspects. Now there is an urgent need for special-purpose rapeseed varieties in the market. Contents of the invention [0003] The object of the present invention is to provide a method for breeding rapeseed for forage by using interspecific hybridization, through which a special type of rapeseed for forage can be bred. [0004] Another object of the present invention is to provide a method of using the forage rape obtained by the ab...
