The present study was conducted at the Tobacco Research Station, Sahiwal, during 1993-94 for evaluating ten promising tobacco accessions, sown in Randomized Complete Block Design with three replications. The mean squares from the analysis of variance indicated highly significant (P is less or equal to 0.01) differences among the genotypes for all the studied plant characteristics. The genotypic and phenotypic correlation between yield and its components among the tobacco accessions showed that studied plant characteristics. The genotypic and phenotypic correlation between yield and its components among the tobacco accessions showed that green leaf yield had significantly positive phenotypic correlation with plant height, leaf size and number of leaves per plant. Number of leaves per plant showed a similar association with plant height and leaf thickness. Therefore, the said plant characteristics may be manipulated to enhance the yield of the tobacco crop.
