Study on various qualitative and quality parameters for distinctness, uniformity and stability test in rice

Seventy six rice genotypes collected from five NARS along with eight local checks from IGKV, Raipur were evaluated for 16 qulitative traits and 12 quality parameters during wet season, 2007. A large number of variations were observed for the visual characters studied. Among the sixteen quantitative traits viz., purple line colour of basal leaf sheath, semi-erect angle flag leaf, intermediate leaf pubescence, 2-cleft ligule shape, green internodes, white apiculus, white colour of stigma and straw hull colour were noticed to have higher percentage of entries. Aroma was present in 40.47 per cent of the entries; for quality parameters viz., paddy length, paddy L:B ratio, length of brown rice, L:B ratio of brown rice, kernel length, kernel L:B ratio, hulling per cent, milling per cent, head rice recovery per cent, kernel length after cooking kernel breadth after cooking and elongation ratio. Finally, data were subjected to statistical and biometrical analysis namely genetic variability, heritability and genetic advance.
