To establish an efficient regeneration system of high-quality rice varieties in Jiangsu Province, the matured embryo was selected as explants from glutinous rice Suyunuo and Nanjing 5055 ,using Nanjing 44 as control.The induction, subculture, differentiation of callus and plant regeneration were compared among these varieties.The results showed that the callus induction frequency of Suyunuo and Nanjing 5055 were 98.81% and 81.00%, respectively, which was slightly lower than that of Nanjing 44 (99.32%) on 20 days after induction with combinations of 2,4-D (3mg/L), KT (0.1mg/L) and ABA (0.2mg/L), using M8 as basal medium.The induction speed of Suyunuo were similar with that of Nanjing 44, while slower speed was observed in Nanjing 5055.
