Abstract: Several characters related to tissue culture abilities, the days of callusing at 50%(DCH), the rate of callusing in 4 weeks(RCW), the rate of Calli of root formation(in %, RCRF), and the rate of calli of shoot formation(in %, RCSF), were analyzed in 76 wheat cultivars originated from South-west China. The results indicate that an extensive variation is found in DCH, NCW, RCRF, and RCSF among different wheat cultivars. A same trend of variation is observed between the DCH and RCW, but not between the RCRF and the RCSF. The method of wheat breeding for transgenic receptors is discussed.
