Abstract 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.
