摘　　要：对"十二五"期间通过四川省审定的9个中籼迟熟优质杂交稻品种的主要特征特性进行了分析。结果表明,旌优127组合在"优、早、丰、抗"等方面表现较好,其次是川优6203。同时针对参试9个组合存在的垩白高这个共性问题,提出从米粒容重和宽厚比方面着手,降低稻米的垩白。Main Characteristic of 9 late-maturing medium indica hybrid rice combinations were analyzed, which was authorized by Sichuan Crop Variety Approval Committee in the 12 th five-year plan. The results showed that the performance of Jingyou 127 is best in＂quality, maturing period, yield and resistance＂, the second is Chuanyou 6203. And for the common problem of high chalk of the 9rice combination, the authors put forwarded some measures to decrease the chalk rice rate and chalkiness degree from grain bulk density and width-thickness ratio.
