| 摘 要： | 以结球甘蓝自交系02-12及其回交转育多代育成的显性核基因雄性不育系（DGMS）和细胞质雄性不育系（CMS）为试材，对其制种产量及种子产量构成因素进行分析。结果表明：显性核基因雄性不育系材料DGMS02-12与细胞质雄性不育系材料CMSR302-12在单株产量和小区产量方面存在显著差异，并且全株有效荚数和每荚种子粒数是两种类型甘蓝雄性不育系间制种产量存在差异的主要构成因素。其中，一级分枝种子产量占单株产量的80%以上，一级分枝有效荚数、每荚种子粒数与制种产量有显著的相关性和较高的通径系数。

| Abstract: | The differences of seed yield and component factors among dominant genic male sterile line DGMS02-12,cytoplasmic male sterile line CMSR302-12 and inbred line of cabbage(Brassica oleracea var.capitata L.)02-12 were studied.The results showed that the differences of seed yield per plant and plot yield between DGMS02-12 and CMSR302-12 were significant.The whole plant valid siliqua and seeds per siliqua were the main factors for the differences of seed yield between these two male sterile lines of cabbage.The s... |
