A Simplified Method for Producing Rapeseed Male Sterile Hybrid F1 Seeds

Abstract

The present invention provides a simplified method for producing rapeseed male sterile hybrid F1 seeds, which comprises selecting a cytoplasmic male sterile line (or nuclear male sterile line) and a restorer line with self-incompatibility to produce hybrid F1 The hybrid seed production method of seeds, its concrete method is, under isolation condition, cytoplasmic male sterile line (or nuclear male sterile line) and restorer line seed with self-incompatibility characteristic are mixed according to specific ratio, will mix The uniform seeds are sown in the field of the rapeseed production area, and the sterile line and the restorer line are mixed when they are mature to produce hybrid F1 seeds. The breeding procedure of the invention is simple, saves labor cost, saves money and labor.

Description

technical field [0001] The invention belongs to the technical field of rapeseed hybrid F1 seed production, and in particular relates to a hybrid seed production for producing hybrid F1 seeds by utilizing cytoplasmic male sterile lines or nuclear male sterile lines and restorer lines with self-incompatibility characteristics method. Background technique [0002] The heterosis of rapeseed is obvious, generally can increase the yield by 20%-30%, and the yield increase rate of good combination can reach 50%. The popularization and application of hybrid rapeseed is developing rapidly. Only the area of ​​hybrid rapeseed in my country has accounted for more than 70% of the total area of ​​rapeseed. The utilization of heterosis is an important way to improve crop yield. There are many ways to utilize heterosis in rapeseed, mainly including cytoplasmic male sterility, nuclear male sterility, chemical male sterility and so on. [0003] Rape male sterility includes cytoplasmic male s...
