Genetics of quality parameters and their associations with grain yield and its component traits have a direct bearing on devising effective strategies for breeding biofortified crop cultivars. A newly developed 54 hybrids of pearl millet showed large genetic variability for yield and nutritional traits. Correlation studies revealed that single plant yield has positive significant correlation with the agronomic traits viz., plant height, number of productive tillers, test weight, single head grain weight and quality traits viz., crude fiber, beta carotene and iron whereas the trait days to fifty per cent flowering alone was recorded negatively significant correlation with single plant yield. It is therefore inferred that simple selection will be effective against positively correlated characters. There is no correlation between grain zinc and yield which suggests that, there is possibility of selection for increased grain zinc content without reducing the grain yield. Maximum direct effect on grain yield was contributed by single head grain weight which is positive and highly significant followed by single head grain weight and number of productive tillers. Results of this present study put forward the way to the development of biofortified cultivars.
