摘要: 为评价花生品种的遗传差异性,本研究应用亲缘系数对江苏审(认)定的28个品种进行遗传多样性分析。结果表明,71.2%品种间组合存在亲缘关系,供试品种亲缘系数(COP)变异范围在0~0.750之间,平均为0.238。同一系列品种间平均亲缘系数并不高,部分品种间亲缘关系较近;不同年代育成品种的亲缘关系均较远,2000年以后品种间亲缘系数仅为0.079 3。通过COP值聚类分析,在欧式距离2.3处,可将供试材料分为5个类群,类群内品种亲缘关系相对较近。江苏花生品种的遗传相似性不高,品种遗传差异较大。

Abstract: In order to evaluate the genetic differences of peanut varieties,the relationship and genetic diversity of 28 peanut varieties in Jiangsu province were analyzed.The results indicated that 71.2% of the varieties showed genetic relationships and the COP(Coefficient of Parentage,COP)values of the combinations ranged from 0-0.750,with an averaged of 0.238.The averages of COP values were low among the same series varieties,with higher COP values in few combinations.COP values were low among varieties in different decades,with only 0.079 3 among varieties produced since 2000.28 varieties could be divided into 5 groups at OUSHI distance 2.3 according to COP analysis,and the genetic diversities in each group were relative lower.The genetic differences and diversity of peanut varieties in Jiangsu province was relative greater.
