Abstract:

Combining ability and heritability of bolting character of four nonheading Chinese cabbage inbred lines were analyzed using Griffing diallel cross I. The results showed that the general combining ability of inbred lines M1112 and M1114 were better, with as boltingresistant potential parental material. The broad sense heritability and narrow sense heritability of bolting character were 9742% and 9141% respectively, and mainly affected by additive genes.So,the selection of bolting characters in nonheading Chinese cabbage was effective in early generations.

Key words: Non-heading Chinese cabbage, Bolting character, Combining ability, Heritability
