VARIABILITY AMONG RECOMBINANT INBRED LINES DERIVED FROM THE CROSS BPT5204 × HPR14 FOR GRAIN PROTEIN CONTENT, AMYLOSE CONTENT, GRAIN YIELD AND YIELD ATTRIBUTING TRAITS IN RICE (ORYZA SATIVA L.).

Rice is a staple food for vast majority of population through out world. In a study an eperiment was conducted to check the variability among the recombinant inbreed lines for the mapping population. Genetic variability, Heritability and genetic advance study for protein content, amylase content, Seed yield and its components was conducted in recombinant inbreed lines (in F9 generation) of Oryza sativa indica L. at the K-block, UAS, Bengaluru, India. Genetic Variance was less than enviormental variance for all the traits. High broad sence heritability and genetic gain were recorded for grain protein content, amylase content, grain yield and yield attributing traits. These results suggest that there is sufficient genetic variability for all the traits studied in the recombinant inbreed lines, Suggesting suitability of the population for mapping.
