ABSTRACT
The present investigation is carried to study genetic parameters for ten yield and yield attributing characters in forty rice genotypes including two checks during kharif 2015. Analysis of variance shows significant difference among all characters under study. The phenotypic variance was higher in magnitude than that of genotypic variance for the yield and yield contributing characters indicates the influence of environmental factors on these traits. The magnitude of difference between phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was relatively high. High phenotypic and genotypic coefficient of variation was recorded for Yield per plant, followed by total no of grains per plant, effective tillers per square meter. Heritability in broad sense estimates were highest for total number of grains per plant, followed by yield per plant, effective tillers per square meter, 1000 grain weight, Effective tillers/plant, number of filled grains per panicle, plant height. High expected genetic advance were observed for characters viz., yield per plant, total number of grains per plant, effective tillers per square meter, Effective tillers per plant, 1000 grain weight. High heritability along with high genetic advance as percent of mean was registered for yield per plant, effective tillers per square meter, total number of grains per plant, effective tillers per plant, 1000 grain weight.
Key words: Rice, GCV, PCV, heritability, genetic advance.
