Abstract:
The present investigation was carried out ARS, Gangavati during Kharif 2021. The experiment was comprised of 20 rice genotypes with 2 replications for both separate Bacillus subtilis treated and untreated in RCBD design. The treated (B. subtilis) and untreated rice genotypes were assessed for heritability, genetic variability and genetic advance for days to 50% flowering, no of tillers per hill, plant height, no of panicles per hill, flag leaf length, panicle length, panicle weight, grain number per panicle, test weight and yield per plant. Analysis of variances for both treated and untreated rice genotypes revealed sufficient genetic variation has been present in all the traits that studied. High heritability along with high genetic advance as percent of mean was found in the traits viz., plant height, panicle number, flag leaf length, panicle weight, grain number per panicle and test weight. High heritability but the moderate value of genetic advance for days to maturity, days to 50% flowering and panicle length in B. subtilis treated genotypes. Thus, selection based on these traits will be effective in improving grain yield in rice along with seedling treatment by B. subtilis. Advances in crop mainly demands the presence of wide genetic variability.
