Nine rice genotypes with increased yield have been identified as suitable entries for zinc deficiency tolerance under aerobic cultivation. Genetic parameters estimated showed that the highest GCV and PCV were observed for zinc score, plot yield, plant harvest index and vegetative vigour. Also, high heritability accompanied by high genetic advance as per cent of mean was observed for zinc score, plant height, plant harvest index, 100 grain weight and plot yield. Therefore, selection for any one of the above characters would bring in simultaneous improvement of other characters and ultimately improving the grain yield. ER -
