Abstract:
The present study was carried out to study yield and yield attributing traits in tobacco, to deliver information regarding the amount of variability, broad-sense heritability, genetic advance over mean and traits association. The experiment was laid out during Rabi 2020 in an Augmented Block Design with 242 genotypes and 4 checks. The box plot analysis revealed that maximum variability for all the traits and the Analysis of variance revealed that the magnitude of the phenotypic coefficient of variance is slightly higher than the genotypic coefficient of variance for all characters studied. Furthermore, a high amount of broad-sense heritability and genetic advance over mean were observed for traits like plant height, number of leaves per plant, internode length, leaf length, leaf width, and yield. This implies that direct selection for these traits might lead to significant progress in discovering superior tobacco genotypes. The character association study revealed that yield was positively and significantly correlated with plant height, the number of leaves per plant, leaf length, leaf width, and internode length hence, selection for these traits will help improve yield.
