Characterising the diversity of grain nutritional and physico-chemical quality in Indian rice landraces by multivariate genetic analyses

Published on

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.
