 ABSTRACT

An experiment was conducted to determine the genetic variability, heritability, genetic advance for yield and quality related traits of 30 rice genotypes in direct seeded rice condition during 2016 kharif season. Significant genotypic differences were observed for most of the traits. Generally PCV was higher than GCV for all the characters. High GCV and PCV estimates over the environments observed for number of tillers per plant, biological yield, grain yield, harvest index, kernel length breadth ratio before cooking, kernel length after cooking, kernel breadth after cooking, kernel length breadth ratio after cooking. Heritability estimates were high for all the characters except biological yield. Plant height, number of tillers/plant, kernel length before cooking, length breadth ratio before cooking, kernel length after cooking, kernel breadth after cooking, length breadth ratio after cooking and elongation ratio exhibited high heritability with high genetic advance as percent of mean over the environments indicating that these characters are more reliable for effective selection. Medium range of heritability with high genetic advance as percent of mean was found for grain yield, harvest index and thousand grains weight.

Key words: Rice Genotypes, Yield, Quality, Genetic variability, Heritability.
