油菜杂种优势利用的一条可能途径——细胞核+细胞质雄性不育

A POTENTIAL WAY OF UTILIZING HETEROSIS IN RAPESSED—GENIC AND CYTOPLASMIC MALE STERILITY (GCMS)

油菜细胞核+细胞质雄性不育(GCMS)三系是在综合了波里马细胞质雄性不育(CMS)三系和细胞核雄性不育两系优点的基础上提出的一种油菜杂种优势利用的新途径。本文根据细胞核雄性不育基因的显隐性的不同,将GCMS分成显性细胞核+细胞质雄性不育三系(DGCMS)和隐性细胞核+细胞质雄性不育三系(RGCMS)。

The proposed genic and cytoplasmic male sterility (GCMS) in this paper has the advantages of cytoplasmic male sterility (CMS) and genic male sterility (GMS) and might be a new way to utilize heterosis in rapessed crops. The GCMS is subdivided into dominant genic-cytoplasmic male sterility (DGCMS) and recessive genic-cytoplasmic male sterility (RGCMS) according to the dominance and recessiveness of the genic male sterile genes.
