摘　　要：为研究花生主要农艺性状的遗传模型,试验以6个花生品种组配的15个完全双列杂交组合为试验材料,进行3次重复的随机区组试验。结果表明:主茎高和饱果数的遗传符合加性遗传模型;果枝数的遗传符合加性-显性-上位性遗传模型;侧枝长、总分枝数、秕果数、百果重、百仁重、出米率和单株果重的遗传符合加性-显性遗传模型,侧枝长和总分枝数表现为部分显性到完全显性,秕果数、百果重和百仁重的遗传表现为完全显性到超显性,出米率的遗传表现为部分显性,单株果重的遗传表现为超显性。此外,还分析了各亲本中控制各性状遗传的显隐性基因比例。Six peanut varieties were used in Griffing Ⅱ mating design for this experiment. The result showed that the height of main axis and number of full pods fitted the additive. Model, number of baring branches fitted the additive-dominance-epistasis model; length of primary branch, number of total branches, number of blighted pods, weight of 100 pods, weight of 100 seeds, ratio of seeds to pods, yield per plant fitted the additive-dominance model. Gene goring the traits of length of primary branch and number of total branches performed partial or complete dominance. Gene goving the trait of number of blighted pods, weight of 100 pods and seeds performed complete dominance or over-dominance. Gene goving the trait of ratio of sees to pods performed partial dominance. And over-dominance was performed by the gene goring the trait of yield per plant. With the exception of this, we also analyze the ratio of the recessive and dominant gene goving the agronomic characters.
