Abstract:
The study aimed to evaluate genetic variability, heritability and genetic advance in the BC1F3 plant for yield and its attributes in non-replicated trial in Summer, 2023. Observations were taken on each individual plant of segregating population for ten different characters. Results showed wide range of variation within population and also confirmed that the mean values of all observed characters in the segregating population ranged between the mean values of parents. Moreover, the values of Phenotypic Coefficient of Variation (PCV) were observed slightly higher than the value of Genotypic Coefficient of Variation (GCV) for all ten observed characters under study indicating minor influence of environmental factors. High heritability was observed for all the ten traits under study revealed the least environmental influence. Higher heritability coupled with high genetic advance as per cent mean is observed for plant height, productive tillers per plant, panicle length, 100 grain weight, grains per panicle, straw yield per plant, harvest index and grain yield per plant indicated the role of higher additive gene action in these traits. The findings from this study provide valuable insights into the genetic architecture of the BC1F3 generation, aiding breeders in selecting individuals with desirable traits for further advancement.
