| Abstract: | By using the gray correlation analysis method,correlation degree for yield of 15 new winter wheat varieties（lines） and seven major agronomic traits were analyzed. The results showed that there has a maximum correlation degree between effective spikes and yield,r value was 0.696 4,and the next were plant height,population density,ear length,grain weight,r values were 0.683 9,0.682 0,0.681 8,0.675 9,respectively. |
