Abstract

Five indica rice cultivars were investigated to study several factors influential to transformation frequency.Appropriate higher ratio of nitrate nitrogen to ammonium nitrogen,1.0~2.5mg/L 2,4-D were beneficial to indica rice callus inducement.The results of subculture time investigation showed that twelve days' culture conduced to callus activity.Advanced research results showed that three days' co-culture of callus and A.tumefacien was beneficial to target gene's transformation.
