Abstract:

The present investigation carried out on 25 rice genotypes during Kharif-2018 at field experimentation centre of Genetics and Plant Breeding, Naini Agricultural Institute, SHUATS, Prayagaraj to assess genetic variability, heritability and genetic advance. Analysis of variance showed highly significant genetic variability for all the 25 rice genotypes for 13 quantitative characters studied indicating that significant at 1% and 5% genetic variability present in the material. High to moderate estimates of GCV and PCV were recorded for number of panicles per hill, number of spikelets per panicle, test weight, flag leaf length, days to 50% flowering, plant height, and grain yield per hill. High estimates of heritability coupled with high values of genetic advance as perecent mean was observe for characyers number of spikelets per panicle, days to 50% flowering, number of panicles per hill and test weight respectively suggesting there was preponderance of additive gene action for the experession of these characters. Hence selection of these traits were useful for further improvement in breeding programme.
