Abstract: Inheritance of resistance to black leaf spot(Alternaria brassicae) in seedlings of Chinese cabbage was investigated by means of "4 × 4" diallel crosses.The results showed that the difference between the resistant and susceptible parents was significant.Two resistant parents showed high positive effect,while two susceptible parents showed negative effect on the resistance to black leaf spot.The reciprocal crossing effect was not significant.The resistance was mainly controlled by nuclear genes with partial dominance. The general combining ability was the most important factor in the resistance.The broad heretability of resistance was 64.45%,while the narrow one was 61.95%.

Key words: Chinese cabbage, Black leaf spot, Heredity
