Abstract::With the plantlets of Chinese cabbage〔Brassica compestris L. ssp. pekinensis(Lour)Olsson〕—cabbage(Brassica oleracea L. var. capitata L.)monosomic alien addition lines as materials, comparison of rooting rate and transplanting survival rate among different monosomic alien addition lines and effect of NAA content in 1/2 MS medium on the root induction were conducted in this paper. The result showed that monosomic alien addition lines AA+C1, AA+C2, AA+C3, AA+C4, AA+C5, and AA+C6 had higher rooting and transplanting survival rate, whereas the rate were much lower for the AA+C7, AA+C8 and AA+C9, adding 1.5 mg?L-1 NAA in 1/2 MS could effectively induce the root initiation and raise the transplanting survival frequency of monosomic alien addition lines AA+C7, AA+C8 and AA+C9.
