ABSTRACT
The present investigation is carried out to study the genetic parameters for yield, yield attributing and nutritional characters in Swarna x Type 3 RIL population of rice. Analysis of variance revealed significant differences among all the treatments under study. The characters viz., number of filled grains per panicle, panicle weight, grain yield per plant exhibited high Genotypic Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV). Small differences between GCV and PCV were recorded for all the characters studied which indicated less influence of environment on these characters. The characters viz., plant height, number of filled grains per panicle, panicle weight, 1000-seed weight, grain yield per plant, grain iron and zinc concentration exhibited high heritability coupled with high genetic advance indicating the influence of additive gene action and simple selection could be effective for improving these characters.
Key words: Micronutrient, Mineral, Phenotypic Coefficient, Yield
