Abstract:
The stability of 10 quantity characters in 13 summer soybean varieties were analyzed by method of regression coefficient and the correlated relationship of yield stability and other character stability was demonstrated by correlated analysis.Results showed that the mean performance of quantity characters in most varieties had significant or greatly significant linear relation with environment index.The yield stability had significantly positive correlation with that of grains of plant,weight of plant and plant height.The stability of grains of plant,weight of plant and plant height may be used as the basis of indirect selection for yield stability breeding of summer soybean.
