Access to genetic diversity in cultivated forage pea (Pisum sativum var. arvense L. )  genotypes through ssr markers

Abstract

Background Forage pea (Pisum sativum var. arvense L.) is an important legume species with high nutritional value used in animal feed nutrition around the world. Forage pea have been grown for animal feeding in the high altitude of the Eastern Anatolia Region for a long time. However, commercial varieties of forage peas are replacing local varieties, especially due to easier seed availability. Therefore, it is aimed in this study is determine of genetic diversity and genome size variation of some forage pea commercial and landraces populations by SSR markers. Methods and results This study was carried out in 2021 with 18 populations in cultivated in Turkey. The 11 SSR markers successfully produced total 66 polymorphic bands by percentage of 89,2% for 18 forage pea (Pisum sativum var. arvense L.) populations. The markers produced a total of 66 alleles. These polymorphic alleles were ranged from 3 to 11 with average of 6. Conclusions Genetic diversity dendrogram was created forage pea cultivars populations. Generally, seven commercial cultivars and eleven populations of forage pea seperated each other as two main groups. As a result of the study, genetic differences were found between pea varieties, and it was concluded that local varieties should be evaluated in breeding programs.
