摘　　要：以2011—2015年四川省水稻审定品种公告为依据,分析了审定品种的主要特点。结果表明,四川"十二五"(2011—2015)期间审定了80个水稻品种,其中,米质达到国标2级的占5%,达国标3级的占7.5%,糯稻1.3%,专用稻12.5%,稻瘟病中抗以上品种3.8%;按熟期分,中籼迟熟占87.5%,早熟占2.5%,中熟占8.8%。"十二五"期间审定中籼迟熟品种的平均产量为8 150.3 kg/hm^2,比对照增产4.94%,没有一个品种减产。"十二五"期间审定品种的产量结构更加合理,其中增幅较大的高产品种的产量结构明显优于产量增幅较小的品种。Based on the data of released rice varieties registered in Sichuan from 2011 to 2015, the characteristics of the registered rice varieties were analyzed. The results showed that there were 80 rice varieties registered in the pe- riod of 12th Five-year Plan （2011 - 2015 ）. Among them, 5.0% and 7.5 % reached the 2nd and 3 ~ class of national quality standards, respectively, 1.3% were glutinous rice, 12.5% were special purpose rice and 3.8% were re- sistant to rice blast with medium or better resistance. If grouped by maturity, 87.5 % of the varieties were late-ma- turing medium indica rice, 2.5% of the varieties were early-maturing medium indica rice and 8.8% are medium- maturing medium indica rice. The average yield was 8 150.3 kg/hm2 for the late-maturing medium indica rice vari- eties registered in the period of 12th Five-year Plan, 4.94% higher than those of the control varieties. Especially, all of the registered varieties including the fine quality varieties yielded higher than their checks. For the rice varie- ties registered in the period of 12th Five-year Plan, the yield components were coordinated better than those in the previous 10 years, and the high-yielding varieties with a greater yield increase had a much better yield structure than those with a less yield increase.
