| Abstract: | The correlation and path analysis showed that number of pods had the greatest effect on the yield of "Liangyou 586",seeds per pod was second,1 000-seeds weight was little effect on the yield.The yield composition such as number of pods,seeds per pod and 1000-seeds weight decided the variation of 97.79% yield.For high yield (2 017.79～2 273.40kg/hm 2),number of pods,seeds per pod and 1 000-seeds weight of "Liangyou 586" should be (2 017.79～2 273.40 kg/hm 2):4 937.86±858.06 kg/hm 2,20.50±0.22 and 4.09±0.02 g respectively. |
