| 摘 要： | 用多元遗传统计分析方法分析了27个花生品种13个性状的遗传关系。结果表明:单株单仁果数、单株荚果重、单株双仁果数的变异系数较大,分别为44.76%、19.07%和17.53%,饱果率、出仁率和总分枝数等变异系数较小,分别为3.23%、7.35%和9.52%;小区产量与单株荚果干重、单株果数、单株双仁果数、百果重和百仁重分别呈极显著正相关,与总分枝数和单株单仁果数呈显著正相关,但与主茎高和第一对侧枝长呈极显著负相关;前4个主成分对变异的累计贡献率达80.66%。

| Abstract: | The method of multiple genetic statistics was used to analyze the genetic correlation among 13 major agronomic characters of 27 peanut cultivars.The results showed that the coefficient of variation of single-kernel pods per plant,weight of pods per plant and two-kernel pods per plant was higher,being 44.76%,19.07% and 17.53% respectively,while that of the rate of filled pods per plant,kernel production rate and total branches per plant was lower,being 3.23%,7.35% and 9.52% respectively.The plot yield was ex... |
