Abstract:

Ecology data of 166 soybean varieties came from the national soybean varieties regional trial in 2004 were used to analysis characteristics of Chinese soybean breeding strains by analysis methods of cluster,principal component and regression.The results showed:1) All of the lines were classified into six groups,breeding target in different ecological zones were responsible for the discrimination of the main characteristics in six group;2) Different ecological zones had different component factors and numbers of principal component factors;3) There are linear relationship between crude protein content and crude fat content,relative coefficient were 0.4991 and 0.2868 respectively,regression model were Y=46.4183-0.1357¢ª₁?and Y=18.1613+0.05014¢ª_2.The research may supply principle theory for breeding program and serve to adjust the distribution of national regional trial
