A study was conducted during kharif 2013 at SHUATS, Allahabad in randomized block design to evaluate genetic variation and heritability of yield and related traits in 98 rice genotypes Genetic variability and character association between yield and its contributing traits were studied in 98 elite rice germplasm. Analysis of variance revealed the existence of significant differences among genotypes for all characters studied. Higher magnitude of GCV & PCV was recorded for biological yield/plant followed by grain yield per plant, flag leaf length, number of tiller/plant and flag leaf width. While moderate was recorded for spikelet per panicle, harvest index, panicle per plant and test weight. High heritability coupled with high genetic advance as per cent of mean was observed for biological yield and spikelet’s per panicle indicating the role of additive gene in expressing these traits. Grain yield was significant highly positively correlated with biological yield, flag leaf length, spikelet per panicle, panicle length.
