ABSTRACT
Present investigation was carried out with the objectives to estimate variability parameters, heritability and genetic advance for 20 yield and yield contributing characters and quality traits in 50 restorer lines of rice. Analysis of variance revealed the presence of significant variability among the restorer lines of rice under study. The genotypes exhibited the highest magnitude of genotypic and phenotypic variances for harvest index, grain yield per plant and grains per panicle indicating the presence of large variation among the genotypes for these characters. The high heritability with high genetic advance was recorded for harvest index, grain yield per plant, grains per panicle, test weight and productive tillers per m2, indicating that most likely the heritability is due to additive gene effects and selection may be effective for these characters.
Key words: Genetic advance, Heritability, Restorer lines, Rice Variability.
