Abstract: The present investigation was conducted to study the genetic parameters such as, variability, heritability, genetic advance, correlation and path coefficient effects on yield and yield attributing characters of fifteen diverse black nightshade (Solanum nigrum L. Complex) genotypes. Analysis of variance recorded highly significant variation among the fifteen genotypes for the eleven quantitative characters. The results of the present study revealed that the higher values of genotypic coefficient variation and phenotypic coefficient of variation were obtained for fresh leaf yield per plant (g) and days to fifty per cent flowering. The same trend on fresh leaf yield as well as days to fifty per cent flowering was followed for heritability estimates along with genetic gain. This reveals that the, influence of environment on these characters are limited and also selection of parents can be made based on them. The characters viz., number of branches per plant, number of leaves per plant, leaf breadth and total alkaloid content had positive and highly significant correlation with fresh leaf yield per plant. Plant height, number of leaves per plant and days to fifty percent flowering showed maximum direct effects through fresh leaf yield. Based on the above results of genetic components, it is suggested that the characters such as number of branches per plant, number of leaves per plant and leaf breadth may be given priority while expressing a selection strategy for yield improvement of black night shade (Solanum nigrum complex L.) genotypes.
