Abstract: A field study conducted with 150 R-lines of pearl millet revealed significant differences in the germplasm for all 12 quantitative traits studied. Characters like biological yield per plant, flag leaf width, tillers per plant and seed yield per plant showed high PCV along with high genetic advance as percent of mean and moderate heritability and GCV. Seed yield had significant and positive correlation with biological yield, tillers per plant, plant height and flag leaf width. The direct and indirect effects of component characters like biological yield per plant, leaves per plant, flag leaf length, flag leaf width, panicle length, panicle diameter, plant height and tillers per plant were found positive on seed yield. Therefore, selection based on these component characters would results in improvement of seed yield also. Genotypes were grouped into 8 diversified clusters. The contribution of seed yield (45.51%) was found highest towards total divergence followed by biological yield (27.53%) and days to maturity (9.23%), respectively.
Twenty genotypes in restorer lines were found reasonably superior in seed yield and other related traits in early maturity and medium maturity group of genotype. Out of them five genotypes namely R-1088, R-1008, R-1095, R-1124 and R-1094 substantially showed higher mean values for seed yield as well as biological yield per plant. Therefore, these genotypes may be used in the breeding programme for developing the dual purpose hybrids for arid zone.
