The main agronomic characters of three peanut varieties (Kailong56, Puhua28 and Zhonghual6) were compared and analyzed in this study. The results showed that the differences in yield per plant, main stem height, side branches length, effective branches length, total branches numbers were significant between two varieties or among three varieties of peanut, other characteristics had no obvious difference. The yield per plant had obvious correlations with plump fruit weight, pod number, plump fruit number, side branches length, and main stem height, the correlation coefficients of them were 0.984,0.903,0.897,0.557 and 0.539 respectively. And the regression equations of yield per plant with plump fruit weight, pod number, and plump fruit number were obtained.%通过对3个花生品种开农56、濮花28和中花16主要农艺性状比较得出,在单株产量、主茎高、侧枝长、有效分枝长和总分枝数这5个方面,两个或者3个品种间具有显著差异,其他性状则没有显著差异.相关分析表明,单株产量分别与饱果重(r=0.984**)、荚果数(r=0.903**)、饱果数(r=0.897**)、侧枝长(r=0.557**)、主茎高(r=0.539**)相关性较好.通过回归分析得到了因变量单株产量与饱果重、荚果数和饱果数3个自变量的回归方程.
