Abstract

A high efficient regeneration system of five indica rice suitable for genetic transformation wereestablished. N6 mediun was suitable for calli induction and subculture of indica rice. The N6 macroelementsand the MS microelements were advantageous to callus formation. By reducing sucrose and supplementingwith sorbitol, copper, silver and zeatin(ZT) to the media, the plantlet regeneration frequencies were evidentlyincreased. The plantlet regeneration frequencies of five varieties were over 75% in these media.
