摘　　要：Despite the economic importance of the peanut, no studies have been carried out to deter-mine the correlation between genetic distances based on molecular markers and on coefficient of parentage （COP） data. In this study, simple sequence repeat （SSR） and pedigree data were used to assess the ge-netic distance between the Fuhuasheng variety and its derivative cultivars. A total of 39 SSR polymor-phism primers were used, and 151 bands were obtained, with an average of 2. 04 bands in each primer. The genetic SSR - based distance （GD） values ranged from 0. 02 to 0. 81, while the COP - based GD ranged from 0. 25 to 0. 98. Certain Fuhuasheng loci displayed higher transmission rates. These loci or nearby chromosomal regions might be associated with desirable traits in Fuhuasheng variety, thus being frequently selected in breeding programs. Therefore, it can be suggested that COP analysis should be the preferred method for estimating genetic diversity invarieties with available complete pedigree information and parents. In this case, marker analysis would provide the best estimations.
