| Abstract: | The statistical methods of cluster analysis and by step discrimination were use d to study 14 soybean varieties of different evolutional types,which were groupe d into 3 clusters by five quantitative characters:days of growth,number of pods per plant,number of nodes per main stem,weight of 100 seeds,clay membrane.The st udy also shows that there is close relationship between genetic divergence and e volutional degree in the groups. |
