Cluster and Principal Analysis of Agronomic Characteristics on Foxtail millet

The cluster analysis and principal component analysis were conducted on 9 agronomic traits index of 52 millet cultivars.The result indicated that the coffident variation of 9 agronomic traits ranged from 16.18% to 60.30%.The cofffident variation of the numer of leaves is lowest with 16.18%,that of kernels per spike is highest with 60.30%,there was variation potential on filed.Based on cluster analysis of anronomic traits,52 millet cultivars were divided into 5 groups.One of groups only including A2-7005,its agronomic traits index were higher than the other clusters except thousand kernels weight.The result of principal analyze showed that,The cumulative contribution of the first six principal factors was 88.91%,which can be indicated the information of all properties.
