Abstract: The present investigation was conducted with 25 genotypes of oats and were grown during rabi 2015-16 to assess the performance, variability, heritability, genetic advance and correlation coefficient analysis using sixteen various yield and yield contributing traits in RCBD with three replications. Variances component method was used to estimate variability and selection parameters using standard approach. The genotypes differed significantly for most of the traits and relatively wide range of the mean for all characters indicated the existence of variation among the tested genotypes. High phenotypes coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were observed for fresh green weight per plant, total number of tillers per plant, number of grains per plant, 100-seed weight and seed yield per plant. High GCV along with high heritability and genetic advance as percent of mean was observed for Fresh green weight per plant, total numbers of tillers per plant, plant height, numbers of grains per plant, 100-seed weight and seed yield per plant. Seed yield per plant was positively and significantly associated plant height, straw weight per plant, harvest index, leaf width, biological yield per plant, and number of grains per plant and 100-seed weight at both phenotypic and genotypic levels. Genotypic path coefficient analysis revealed that number of leaves per plant showed maximum positive direct effect on seed yield and also exhibited positive correlation with seed yield per plant. This study showed that there exists a large genetic variation among oats genotypes for most of the characters which could be exploited for direct selection of high yielding genotypes
