Character association and path coefficient analysis of yield and its contributing traits in garlic (Allium sativum L.)

Abstract

Sixty genotypes including four check varieties (G-50, G-41, G-282 and Punjab Garlic) of garlic (Allium sativum L.) were assessed to work out the association of different yield traits, direct and indirect effects of their various attributes on yield per plant. The number of cloves per bulb exhibited highly significant and positive phenotypic correlation with bulb yield per plant whereas, highly significant negatively correlated with weight of clove. Total soluble solids exhibited highly significant and positive correlation with bulb yield per plant. The highest direct positive effect towards bulb yield per plant was observed for number of cloves per bulb, weight of clove and total soluble solids, at phenotypic level. However length of leaf, diameter of bulb, length of clove and diameter of clove had exerted negative direct effect on bulb yield per plant. The number of cloves per bulb via length of bulb, number of cloves per bulb via length of leaf and weight of clove via length of clove, had exerted maximum positive indirect effect on bulb yield per plant.
