Genetic variability, heritability for quantitative traits in upland rice (Oryza sativa L.) genotypes
ABSTRACT
The present investigation consists of 34 genotypes with one local check (NDR-359) grown at field experimentation centre at the Department of Genetic and Plant Breeding, SHIATS, Allahabad evaluated for thirteen quantitative characters. All the genotypes differed significantly with respect to all the quantitative traits. High to moderate estimates of GCV and PCV were found for number of panicle per plant, number of tiller per plant, plant height and number of spikelet’s per panicle, indicating these traits could be use for selection in crop improvement. Plant height, number of spikelet’s per panicle, test weight and flag leaf length exhibited high values for broad sense heritability. Number of spikelet’s and plant height showed highest genetic advance coupled with high heritability, which is also exhibited by number of panicle per plant, number of tillers per plant and plant height suggesting pre dominance of additive gene action in the expression of these traits.
