Genetic Variability, Heritability and Genetic Advance Studies on Yield, Its Components, Quality Traits and Gall Midge Incidence in Rice (Oryza sativa L.)

Twenty-eight lines including 18 F1 plants, 9 parents, and one commercial were studied for estimation of genetic variability, heritability, advance at Agricultural Research Station, Kunaram. Analysis variance revealed highly significant differences among the genotypes all traits indicating presence a considerable amount variability yield its components, quality gall midge incidence. PCV values number productive tillers per plant significantly greater than GCV sensitive to environmental changes. The high percentage incidence, plant, filled grains panicle, grain whereas, low hulling percentage, head rice recovery, milling kernel length. Additive gene action was predominant Gall weight 1000 as they registered heritability coupled with values.
