Principal component analysis and metroglyph of variation among sesame (Sesamum indicum L.) genotypes

A study was carried out by using 45 genotypes of sesame at Seed Research and Technology Centre, Hyderabad during 2018 to evaluate the genetic variability, morphological clustering Metroglyph identify principle components having a major contribution total variation. Analysis variance indicated appreciable variation among for traits. The Julang Sesame NI8-8316 recorded highest average performance seed yield per plant other components. trait, value GCV PCV followed test weight. High heritability together with high values advance showed 1000 weight seeds individual pod. Principal component analysis (PCA) three eigenvalue more than one contributing 78 % towards variability population. clustered into six groups group IV being largest 20 genotypes.   Cluster VI characterized number pod comprised including NI8-8316. overall that were superior in could  be  utilized as parents hybridization programs.
