| 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。

| Abstract: | 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 ... |
