Abstract:
In the present experiment 24 landraces of rice from Telangana, Karnataka, and Chhattisgarh were used to conduct the research work. In Kharif (2022), the research work was conducted through a Randomized Block Design (RBD) with three replications at the research farm of the M.S. Swaminathan School of Agriculture (MSSSoA) at Centurion University of Technology and Management (CUTM), Paralakhemundi, Odisha. Total 15 quantitative parameters were recorded in order to evaluate genetic variability, heritability, and genetic advance. The analysis of the experimental data showed that the genotypes have a lot of variation. The investigation's findings revealed that characters such as the number of tillers per plant, the number of effective tillers per plant, the number of filled grains, the number of unfilled grains, and the grain yield per plant, all had high estimates of GCV and PCV. The plant height showed low levels of GCV and PCV, and the traits 1000-seed weight, number of tillers per plant, number of effective tillers per plant, number of grains per plant, kernel length, number of filled grains, grain yield per plant and number of unfilled grains all showed high heritability along with high genetic advance as mean percentage. For grain breadth, low genetic progress and low heritability were observed.
