Use of Rapd Markers

The genetic diversity of pea accessions collected by the NPGRC was evaluated via RAPD markers as reference for germplasm collection and breeding programs.

Three Groups Determined

The results indicated that all the pea accessions analyzed could be divided into three groups and five individual accessions. The polymorphic bands ranging from 3 to 11 were generated by 38 random primers, with an average of 6.1 bands each.

Range of Genetic Similarity

The lowest and highest genetic similarity recorded were 0.626 and 0.978, respectively. The phylogenetic relationships were revealed accurately and genetic diversity tested in this research could be used to broaden the genetic basis in breeding programs.
