Genetic Diversity Among Some Traditional Aromatic Rice (Oryza Sativa L) Varieties of Orissa

Twenty aromatic rice genotypes collected from different parts of Orissa were evaluated for their performance during kharif 2007. Data generated on seven biometrical characters were subjected to analysis of variance and results indicated significant differences among genotypes. Estimation of mean, range, standard deviation, standard error and coefficient of variation (CV) indicated wide variation among traditional aromatic rice genotypes cultivated in the region. Classification of genotypes following Numerical Taxonomic analysis indicated five different classes. Grouping of genotypes and their characterization provided useful information about their relatedness and possible use in crop improvement programme.
