摘要
以2个耐抽薹的甘蓝高代自交系和2个易抽薹的甘蓝高代自交系为亲本,按照Griffing完全双列杂交方法Ⅰ配制杂交组合,对其抽薹期性状进行配合力和遗传力分析。结果表明:耐抽薹自交系LN-0901和LN-0913的一般配合力和特殊配合力都较高,宜用于杂种优势育种。抽薹期性状主要由基因的加性效应控制,广义遗传力为96.42%,狭义遗传力为67.68%,在育种实践中适宜进行早期世代选择。
Combining ability and heritability of bolting characters of 4 cabbage(Brassica oleracea var.capitata L.)inbred lines were analyzed according to GriffingⅠmethod.The results showed that the general combining ability and special combining ability of inbred lines LN-0901 and LN-0913 were better,which are fit for heterosis-cross-breeding.The broad sense heritability and narrow sense heritability of bolting characters were 96.42 % and 67.68 %,respectively,and mainly affected by additive genes.The selection of bolting characters in cabbage is effective in early generations.
