Abstract:
The present investigation was carried out with an objective of assessing the genetic variability, heritability, genetic advance for twenty-two yield and quality characters of thirty rice genotypes evaluated in RBD with three replications. The results of ANOVA revealed that the mean sum of squares among the genotypes for all the characters were highly significant indicating the presence of ample amount of variability which can be exploited for selection of characters for crop improvement programme. The value of PCV and GCV was observed highest in case of flag leaf width .Genetic Advance as a percent of mean was maximum in case of grain yield per plant followed by number of grains per panicle, grain weight per panicle and water absorb by kernel while minimum for hulling percent and days to maturity. On the basis of study, the desirable donors for each character were identified. The most promising donors for grain yield were SKG-2017-19, SKG-2017-64, SKG-2017-40, SKG-2017-06 and SKG-2017-17. These genotypes can be used for further breeding programme to improve the yield potential of the variety.
