Forty four germplasm accessions of amaranth spp were evaluated during rabi-2016 for assessing the genetic variability present in the material for grain yield and yield related traits. Analysis of variance revealed significant differences among the genotypes for all the characters studied. High PCV and GCV was observed for number branches per plant, number of panicles per inflorescence, number of inflorescence per plant, panicle length (cm), panicle breadth (cm), thousand seed weight (mg), seed yield per plant (g), inflorescence length (cm), plant height at 90 das (cm) and stem diameter (cm). On the other hand, low PCV and GCV were observed for days to seed maturity. All the traits studied exhibited high heritability. High genetic advance as per cent of mean was observed for number branches per plant, number of inflorescence per plant, number of panicles per inflorescence, panicle length (cm), panicle breadth (cm) and thousand seed weight (mg) and seed yield (g) indicating predominance of additive genetic component in expression of these traits. Thus, there is scope for improvement of seed yield by adopting selection.
