Genetic Diversity Studies of Soybean [Glycine max (L.) Merrill] Germplasm Accessions using Cluster and Principal Component Analysis

Background: Soybean [Glycine max (L.) Merrill] is a self-pollinated diploid leguminous crop (2 n=40) originated from China. It called as ‘Cow of the field’ or ‘Gold soil’ because high oil and protein content. The objective study to determine genetic diversity using cluster principal component analysis among 135 soybean germplasm. Methods: experiment was conducted at Department Pulses, Tamil Nadu Agricultural University, Coimbatore during rabi, 2021-22. A total germplasm laid down in augmented block design II. Principal were performed accessions GRAPES Ggt 2.0 software respectively. Result: Based on components analysis, wide observed MAUS 60, JS 98-61, MACS 1460, EC 18736 PK 1038 genotypes traits viz., number clusters per plant, pods plant single yield contributed divergence. above mentioned could be used for selection future breeding programme.
