Character Association and Path Coefficient Analysis Among Economic Traits in Makoi (Solanum nigrum L.)

J. Shivanna, C.S. Ravi, B.S. Sreeramu

Abstract


Genotypic and phenotypic correlations and path coefficient were studied for 12 economic traits in 17 genotypes of makoi (Solanum nigrum L.). The genotypic correlation coefficients were higher than phenotypic correlation coefficients for most of the traits. The total alkaloid yield has a highly significant positive genotypic and phenotypic association with total alkaloid content and a significant association with dry herbage yield per plant. Days to flower bud initiation and days to 50 per cent flowering had significant positive association only at the genotypic level, Path coefficient analysis revealed the maximum direct  effect of the total alkaloid content followed by dry herbage yield per plant. Thus, selection based on high total alkaloid content and dry herbage yield would be favourable in achieving sustainable gains in makoi with high total alkaloid yield.
