Quantity Character Analysis and Cluster Analysis of 21 Local Peanut Varieties in Guizhou

Through the character comparison, correlation coefficient analysis and cluster analysis based on agronomic characters observation both in field and in laboratory on 21 peanut varieties, the result showed that the aberrance coefficient of the effective length of branches, effective branches, effective pods per plant, weight per. 100 seed and yield per plant are great. These varieties can be chosen for crossbreed and selection breeding. The pod yield per plant were best and significantly positive correlated with 100 pods weight and pod number per plant. 21 local peanut varieties can be classified to 3 types.
