Agronomic Characters Analysis of Dual-purpose Peanut Varieties Under Different Soil Conditions

Comparative studies on variation of agronomic characteristics as well as the yield of the kernel and stalk in five peanut varieties were carried out with different soil conditions.The results showed as follows: the ability to adapt to different soil conditions is discrepant, even the same varieties of peanut. The biological yield is also changed in two soils. In sandy loam the yield both of the kernel and stalk showed a highly significant positive correlation with plant height and branch length respectively. But there was a significant positive correlation between the yield and pod number per plant in clay loam.It is concerned that the yield of the kernel and stalk were negative correlated with which including 100-pod weight, 100-kernel weight, shelling percentage. Shan G was better than both Shan E and Quanhua No.7 between peanut yield and peanut vine yield in clay loam. It was a comprehensive advantage prominent peanut variety.
