In order to provide references for effectively use the right peanut varieties,67 main peanut cultivars and lines were chosen as materials,which were from Hebei,Shandong and Henan province.The relation between the pod yield per plant(PYP) and 8 characters were analyzed seperately,the 8characters included the kernel percent,100-pod mass,100-kernel mass,the days from seedling to 50%flowering(DSF),the days from seedling to maturity(DSM),the main stem height,the No.of fruit branches and the No.of pods.The 67 materials were compared and classified by cluster analysis.The results showed that 2 characters,the kernel percent and 100-kernel mass,were negatively with the PYP,especially the former,which reached a very significant level;the other 6 characters were all positively correlated with the PYP,and their statistically coefficients of correlation reached very significant level but the 100-pod mass and the main stem height.The No.of pods was the most important character in 5 positive characters that improve the PYP,and the kernel percent was the most important character in 3 negative characters which decreas the PYP.The regression equation established by the PYP and the other characters reached a very significant level,it could be used on the forecast of production practice.The third kind of varieties was chosen as high-yield cultivars by cluster analysis.When making breeding objectives,breeders should focus on characters with both high heritability and high correlation with economic characters,and farmers should read the reports of regional trial made by government before choosingthe cultivars.
