    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 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%. Basing on their principal component , we judged the traits of every germplasm resource and selected 10 cultivar with better multiple traits to be used as parents in breeding . The genetic distance were calculated using the value of the first 4 principal component. Divided them into 6 groups at the level 0f D2=3.21, which basing on the value of genetic distance. Among 6 groups ,theⅡgroup had the most(16parts) number cultivar, and its multiple traits also displayed better . The most cultivar of theⅡgroup could be used to utilize as breeding parent or be spreaded.
