1997～2007年通过四川省区试审定的小麦品种述评

Review of the release wheat cultivars through Sichuan provincial trial during 1997 to 2007

总结1997-2007年间通过四川省区试审定的72个小麦品种。根据四川省审定公告和四川省小麦区试资料，列出72个品种在省区试中的产量及与产量有关的部分农艺性状数据，以及审定公告的品质性状数据和抗性表现，并分析这些品种的产量和农艺性状。认为目前四川小麦品种区试平均产量水平介于5—5．5t／hm^2之间；基本产量结构为290～360万穗／hm^2、40～45粒／穗、40-45g／1000粒。今后四川省小麦产量育种应当在保持现有产量结构的基础上，注意增加穗数和增加千粒重两个方向的突破，建立新的平衡，实现四川小麦产量的进一步提高。

The data of 72 release wheat cultivars through Sichuan during 1997 to 2007 were analyzed. The result showed that： （ i ） yield level of the release wheat cultivars in Sichuan province trial was between 5 - 5.5 t/hm^2 ; （ ii ） the yield component of that wheat was that ：290 - 360 104 spikes/hm^2 ear number,40 -45 grains per ear, 1000 grain weight between 40 -45 g. Ear number on unit area and grain weight would be two key traits in yield improvement in Sichuan in the future.
