| 摘 要： | 摘要：本文对27份花生种质资源的10个主要农艺性状表现进行了变异和主成份分析，结果表明：单株秕果数、单株结果数、主茎高与单株双仁果数变异系数较大；前4个主成份对变异的累计贡献率达84.98%。根据各种质资源的主成份值判断其表现特点，选出了综合性状比较理想的10份品种作为育种亲本。利用各种质资源的前4个主成份值计算各品种间的遗传距离，按遗传距离大小在D2=3.21水平下将27份种质资源聚类划分为6大类群，其中Ⅱ类群品种数最多(16份)，该类群品种综合性状也表现较好，大多可为育种亲本利用或推广种植提供选择。

| Abstract: | The variation and principal component analysis of 10 principal agronomic traits in 27 peanut germplasm resources were conducted.The results indicated that the coefficient of variation of individual deef-pod,inividual pod,plant high and individual two-seed were bigger.The accumulative contribution rate of the first 4 principal component were 84.98%.Based on their principal component,we judged that the traits of every germplasm resource and selected 10 cultivar with better multiple traits to be used as parent... |
