摘　　要：为了解黄淮麦区小麦种质资源农艺性状的遗传多样性，对85个品种（系）的12个叶、穗部及其他农艺性状进行了鉴定。结果表明：12个农艺性状具有较大的变异幅度，最大的是芒长，变异系数为36．8％；变异系数最小的是籽粒灌浆期，为6．4％。欧氏距离的变异区间为1．85—11．32，平均为5．62。在欧氏距离为16．25处可以把所有品种分为3大类6小类。In order to understand the genetic diversity of the wheat varieties in Huang - Huai Wheat Area, 12 agronomic traits of 85 wheat varieties were measured to provide more useful information about wheat genetic resources for breeders. The results showed that there was a greater range of variation in 12 agronomic traits. Among them, the length of arista had the greatest coefficient of variation which was 36. 8%, The variation coefficient of the length of grain filling stage was the smallest, which was 6.4%. The variation interval of the Euclidean distance was 1.85 - 11.32 with an average of 5.62. The 85 varieties could be divided into 3 major categories and 6 sub - groups at the Euclidean distance of 16.25.
