Abstract: One hundred rice genotypes released for different ecologies such as upland, irrigated, lowland and saline were evaluated for 12 quality characters like Hulling(%), Milling(%), Head rice recovery(%), Kernel length(cm), Kernel breadth(cm),Length breadth ratio, Volume expansion ratio, Elongation ratio and Amylose content(%) etc. Analysis of variance showed high significant difference among the genotypes. Milling(%) is very good in all the genotypes and ranged from 74.5(PR113) to 81.3 (Improved Lalat). HRR (%) is highest in Bhanja (72.0) and lowest in Konark(42.5). Intermediate amylase content are in most of the genotypes except GR 103(27.1),IR 64 MAS(27.86) WGL32100(27.3), WGL32183(27.5)and Purnendu (27.9). Water uptake ranged from 77.5(WGL 32100) to 342.5(PR116) indicating very wide variation. Elongation ratio is > 2.0 in Sudhir, Sashi, Bindli. PCV is always greater than GCV indicating less influence of environment. Hulling (%) is positively significantly correlated with Milling (%) and kernel breadth and negatively significantly correlated with L/B ratio, volume expansion ratio.
