摘　　要：川麦２２是利用收获指数作为选择指标之一育成的小麦品种，１９８９—１９９２年，累计推广１．１百万公顷。本文报告利用收获指数，并结合其他主要农艺性状，选育出川麦２２的过程，研究和分析了川麦２２在全省８６点（次）试验中的产量及产量构成因素的变化规律，以及该品种对条锈病的抗性反应，指出川麦２２的丰产潜力与绵阳１１相同，但稳产性和适应性明显优子绵阳１１，含有与２个杂交亲本不同的苗期抗性基因，抗条锈病性优于绵１１。Chuanmai 22 is a variety selected by using harvest index(HI) as one of the important objective characters.It covered more than 1.1 million hectares from 1989 to 1992.This article reported how to select a variety using HI combined with other main agronomic traits and studied its yield and yield components in the test of 86 sites(times) in Sichuan Province,and analyzed its resistant reaction to stripe rust.The conclusion was that the yield potential of Chuanmai 22 was equal to Manyang 11(CK), and its yield stability and adaptability were better than CK.It was also concluded that there were some stage resistance genes exsisting in Chuanmai 22,which was different from its 2 parents(one was Manyang 11),and so its resistance to the disease was better than CK.
