The nature and amount of genetic variability, associations, co-heritability, and path coefficients were studied in the eleven qualitative and quantitative traits in twenty-nine genotypes of Hyoscyamus niger. The highest genotypic and phenotypic coefficient of variations was recorded for total crude tropane alkaloids (77.77) followed by hyoscine content (49.42) and hyoscyamine (32.313) content in percent and lowest for days to maturity. Total crude tropane alkaloids ((ĥ2 bs) = 92.94%, GA = 149.24%) showed high heritability in broad sense, as well as high genetic advance over mean in percent. Plant height, inflorescence length, total crude tropane alkaloids and hyoscyamine content were highly significantly and positively correlated hyoscine content at both genotypic and phenotypic level while, plant height was significantly negatively correlated with number of primary branches/plant. Fresh herb yield (g/plant) exhibited high co-heritability with inflorescence length and hence it may form a good selection criterion for valuable economic traits. The path coefficient under study revealed that the highest direct contribution to total crude tropane alkaloids was made by plant height (0.994) followed by hyoscyamine content (0.420) and number of branches/plant (0.393) in percent.
