Breeding of the Recessive Genic Male Sterility Line with the Same Genetic Background as Its Temporary Maintainer TAM by Marker-assisted Selection

分子标记辅助选育油菜 RGMS 保持 系TAM的同核不育系

Based on this genetic model a 100 % male-sterile population could be produced by crossing a homozygous male-sterile line with a temporary maintainer line .

根据这一遗传模型，将纯合不育系和 临 保 系杂交就可以获得100%不育群体，避免了传统隐性核 不育 系在杂交种生产过程中拔去母本行50%可育株的麻烦。
