Abstract
Estimation of nature and degree of divergence for different traits is useful for planning crossing programme and to recover desirable recombinants. Genetic divergence may be assessed either by D2 statistics or by metroglyph analysis. The present investigation was carried out with 35 diverse genotypes of groundnut to classify them in distinct classes using metroglyph analysis. In graphical representation two most important characters, pods per plant and dry pod yield per plant were represented on X axis and Y axis, respectively. Genotypes UG 21, UG 22, UG 24 and UG 29 were identified as desirable for pods per plant, while genotype UG-11 for dry pod yield per plant. Desirable genotypes for other six traits were identified by length of rays occupying specific positions on the glyphs. For 100-kernel weight five genotypes and for oil content six genotypes were identified. The identified genotypes may be suitably used in hybridisation programmes to combine economic characters resulting in a high yielding groundnut cultivar with improved quality
