Abstract

Rice (Oryza sativa L.) is a major cereal crop in the world, particularly in Asia, where it is a staple food for 90 % of the population. The current research was aimed at determining the better genotypes for cooking quality characteristics by utilizing forty-three genotypes of rice along with two checks, viz: Pooja and RNR 15048. The experiment was carried out during the summer season of 2024 at Post Graduate Research Farm, M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi, India. The design of experiment was Randomized Block Design (RBD) with three replications. Study revealed significant difference among all the studied parameters through analysis of variance which extend scope of further study. Genetic parameters revealed that phenotypic coefficient variation is higher than genotypic coefficient of variation indicates along with genotypic environment also played key role to influence the studied characters. High heritability coupled with high to moderate genetic advance as percent of mean noted for all the studied characters signify the predominance of additive gene action henceforth, direct selection would be rewarding. Character association and partial regression study revealed significant association among the studied variables. The significant character such as seed protein content highest exhibited by POO7SD (8 %), amylose content exhibited highest in Durgasal (24 %), on contrary lowest was revealed by Mugi (10 %). Genotypes RNR 15048, Pusa Basmati and POO7SD were found to be superior for biochemical and cooking quality traits and hold promise for future programs of improvement. Which clearly signify future potential to unravel qualitative breeding by seeing India’s opportunities in global market through Basmati rice. Therefore, further exploration of aforementioned genotypes will ultimately help to strengthen India’s qualitative rice market in domestic and international pace.
