Genetic Diversity of Peanut Varieties in Jiangsu Using Coefficient of Parentage

doi:10.7668/hbnxb.2011.S2.005

Abstract

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.

Key words: Peanut, Coefficient of parentage, Genetic diversity
