Abstract:

Thirty basmati rice genotypes were evaluated in RBD with three replications with an objective of assessing the genetic variability, heritability, genetic advance for twenty-two yield and quality characters. 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 grain weight per plant followed by water absorb by 10 g kernel and number of grains per panicle. Heritability in broad sense was found high for all characters, while genetic advance as a percent of mean was recorded high for all characters except hulling %, for which moderate GAM was observed. On the basis of study, preponderance of additive gene action was revealed for all the traits except hulling %. The most promising donors identified for grain yield were SKG-2017-56, SKG-2017-75, SKG-2017-65, SKG-2017-59, SKG-2017-66. These genotypes can be used for further breeding programme to improve the yield potential of the varieties.
