Abstract:
The present study was conducted at Research cum Instructional Farm, S.G. College of Agriculture and Research Station, Kumhrawand, Jagdalpur, Bastar, Chhattisgarh, India. One hundred and four rice genotypes lines were planted in three rows in two replication with four checks included: MTU 1010, Karma Masuri, Dub-raj Selection and HMT in Randomized Complete Block Design. Analysis of variance revealed significant differences for all the traits under study. The characters viz., Volume expansion ratio, grain length, Grain breadth, Grain length breadth ratio, kernel length, Kernel Breadth, Kernel length breadth ratio, gel consistency were middle of the exhibited high Genotypic Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV). On the evaluation of small differences between GCV and PCV were recorded for gel consistency under present studied which indicated less influence of environment on these characters. The characters gel consistency and grain length exhibited high heritability coupled with high genetic advance indicating that simple selection could be effective for improving these characters.
