Abstract:
The BC₂F₂ population of ADT43 X RP-Bio-Patho-2 was used for the current experiment. The present study examined sixteen quantitative variables for genetic variability, heritability, genetic advance, skewness, and kurtosis. For the trait's number of productive tillers, number of filled grains per panicle, and number of grains per panicle, a high level of variability was observed. This variability was expressed as a high phenotypic coefficient of variation (PCV), and genotypic coefficient of variation (GCV), along with high heritability and genetic advance as percent of the mean. Plant height, number of productive tillers per plant, number of filled grains per panicle, grain L/B ratio, kernel L/B ratio before cooking, and grain yield per plant showed higher to moderate estimates of PCV and GCV. Higher estimates of heritability and genetic advance for the same traits also suggest the presence of additive genes in the traits. Therefore, crop advancement programs will be benefitted from selection based on these traits.
