1986年水稻原生质体再生植株获得成功以来,国内外对原生质体再生植株及其后代的性状变异已有一些报道,1988年中国科学院遗传研究所培育籼稻品种大谷早原生质体再生植株成功,1988-1990年我们对大谷早再生植株及其后代R_26个株系360植株的形态性状变异,进行了系统的田间 Since the success of regenerating rice protoplasts in 1986, there have been some reports about the variation of protoplasts regenerated plants and their offspring at home and abroad. In 1988, the Institute of Genetics of Chinese Academy of Sciences succeeded in cultivating protoplast regenerant plants of Indica rice varieties, 1988-1990 In the year, we conducted a systematic field experiment on the morphological traits of 360 plants from R26 lines of early regrowth plants and their progenies
