We evaluated a set of 190 genotypes for five grain-nutrient,
five grain physico-chemical quality and four derived traits.
Wide variability was observed for all the traits studied, with
CV ranging from 9.33 to 51.89%. No correlation was observed
between grain nutritional and physico-chemical quality
traits. Iron (Fe) and Zinc (Zn) content in brown rice showed
significant positive correlation. Zn content in brown and
polished rice showed significant association however, the
Fe content in brown and polished rice did not show
significant association. Two principal components each
in grain nutritional and physico-chemical traits explained
73.15 % and 62.82 % of the total variation, respectively.
Cluster analysis grouped the accessions into two and three
clusters on the basis of grain physico-chemical traits and
nutritional traits, respectively. The study has led to the
identification of promising donors for biofortification and
grain quality improvement in rice.
