Estimation of the Genetic Variability of an Amaranth Collection (Amaranthus L.) by RAPD Analysis

The genetic variability of an amaranth collection was studied by RAPD analysis. A high level of polymorphism of the studied samples was detected. It was about 85% on average. Unique fragments characteristic of only definite accessions and 18 monomorphic loci proper for all amaranth accessions were detected using several primers. The genetic distances of Nei and Li were calculated. This index varied from 0.0009 to 0.0141. A cluster analysis was carried out. The amaranth accessions were classified into two clusters according to the species affiliation. DOI: 10.3103/S0095452712040093
