Diversity analysis in Arachis subspecies using phenotypic characterization and microsatellite (SSR) markers

Groundnut (Arachis hypogaea L.) is one of the important economic crops world. It world’s fourth most source edible oil and third vegetable protein. A study was conducted at Department Seed Science Technology, B. A. College Agriculture, AAU, Anand, to investigate morphological molecular characterization in different Arachis spp. The experiment laid out randomized complete block design with two replications evaluated for 28 quantitative 20 qualitative characters. Genetic distances among genotypes obtained from analysis traits ranged 1.00 between pairs ICG1994 AG2245 upto 9.70 ICG6813 JB1180. Dendrogram developed using average taxonomic distance matrix by UPGMA method formed four major clusters. dendrogram could not establish any distinct relationship botanical groups. However, few belonging spanish bunch group tend cluster together exhibiting their common phylogenetic relationship. This also evident case Virginia cultures where a observed. Pooled SSR 50 groundnut 23 primers generated total 1293 scorable bands 251 alleles. PIC value 0.670. genetic similarity coefficient markers this 0.27.
