Abstract: Qualitative traits are considered as morphological markers in the identification of genotypes of rice because they are less influenced by environment. Thus, characterization of germplasm accessions establishes distinctiveness among rice genotypes. Coleoptile colour, anthocyanin coloration of leaf, intensity of anthocyanin colouration, pubescence of blade surface, density of pubescence of lemma, lemma and palea colour, colour of awns, attitude of branches of panicle, and decorticated grain shape showed maximum variation among accessions. The analysis of variance indicated that the mean sum of square due to genotypes were significant for all the qualitative and quantitative characters. This indicates the presence of considerable variability among the accessions. Highest genotypic and phenotypic coefficient of variation was shown by head rice recovery percentage followed by Kernel length Breath Ratio and Flag leaf width. High heritability coupled with high genetic advance as percent of mean was observed for head rice recovery, cooked kernel L/B ratio, kernel L/B ratio, grain L/B ratio, 1000 grain weight and elongation index, indicating that selection for these traits is likely to be effective accumulation due to more additive genes leading to further improvement in their performance.
