辣椒雄性核不育基因的遗传研究及其在杂交育种中的应用

Genetic Study on Genic Male Sterility of Pepper and Its Application in Hybrid Breeding

摘要:

辣椒(Capsicum annuum L.)雄性核不育和核-质互作型不育类型已在杂交种的选配中得到应用。核不育类型由细胞核内的基因控制,而核-质互作型雄性不育则由细胞核和细胞质内的基因共同控制。综述了辣椒雄性不育的遗传及其杂交育种的研究进展,包括辣椒连锁遗传图谱的构建、核基因的定位、连锁分子标记的发展,为深入研究辣椒雄性不育的遗传机理及基因克隆提供参考。

Abstract:

Genic male sterile (GMS) and cytoplasmic male sterile (CMS) have widely used in pepper breeding. GMS is controlled by nuclear genes, while CMS is regulated by both nuclear genes and cytoplasmic genes. The advanced studies on genetics and application of pepper male sterile in hybrid breeding, the construction of genetic linkage map, gene mapping, and the development of molecular markers were reviewed, which will benefit the further researches of genetic mechanism and gene cloning in pepper.
