The morphological characterization of the genotypes as per the DUS norms revealed that more than 50% of the genotypes had absence of coleoptile anthocyanin colouration, green foliage colour and awned, intermediate type of growth habit, absence of waxiness and medium pubescence. The genotypes were also evaluated for variability parameters and correlations for seven metric traits. Significant genotypic differences were observed for all the traits studied indicating considerable amount of variation among genotypes for each character. The estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were high for proline content and number of grains per earhead, moderate for earhead length, peduncle length, number of effective tillers per plant and plant height. The heritability estimates were high for all the traits studied. The expected genetic advance as per cent means were high for proline content, number of grains per earhead, earhead length, peduncle length, number of effective tillers per plant and plant height and moderate for total phenols. Plant height exhibited highly significant and positive genotypic and phenotypic correlation with peduncle length, number of effective tillers per plant and non-significant and positive genotypic and phenotypic correlation with total phenols and earhead length.
