GENETIC VARIABILITY AND SELECTION CRITERIA IN RICE
Journal Title: Journal of Biological and Scientific Opinion - Year 2013, Vol 1, Issue 4
Abstract
Genetic parameters, correlation and path analysis for 12 yield and quality traits were studied during rabi, 2009-10 in 21 genotypes of rice. High estimates of GCV were recorded for plant height, number of filled grains/panicle and grain yield/plant. Heritability in broad sense was high for all the characters except spikelet fertility. High heritability coupled with high genetic advance as per cent mean were recorded for number of productive tillers/plant, panicle density, number of filled grains/panicle, 1000-grain weight, grain yield/plant and kernel length. Grain yield/plant exhibited highly significant and positive correlation with days to 50 % flowering, plant height, productive tillers/plant, panicle length, panicle density and filled grains/panicle. Path coefficient studies indicated maximum direct positive effect of plant height, productive tillers, filled grains/panicle and kernel length and kernel breadth on grain yield/plant.
