Abstract
Genetic variability, correlation and path coefficients were studied in 48
genotypes of tobacco during kharif 2015-2016 at Bidi Tobacco Research Station,
Anand Agricultural University, Anand.
The analysis of variance revealed significant differences for all characters
under study. Characters viz., seed yield per plant, days to fifty per cent flowering,
number of leaves per plant, plant height, number of branches per plant, number of
capsules per plant, test weight, khakhri yield per plant and harvest index had high
genotypic coefficient of variance, high heritability and high genetic advance
expressed as percentage of mean indicating that phenotypic selection could be
effective in improvement of these characters. The estimates for above parameters
were low for seed oil per cent except heritability.
