The experiment was conducted in Augmented Block Design at Main Experimental Station of Department of Vegetable Science, Narendra Deva University of Agriculture, Narendra Nagar (Kumarganj), Faizabad (U.P.) during Rabi 2014-15 with the following objectives (1) to find out the correlation among yield and yield contributing traits, and (2) to study the direct and indirect effects of different traits on yield. Experimental material for the present study consisted of thirty genotypes. In single plot sized 2.0 X 0.30 cm with the distance of 30 cm row to row and 10 cm plant to plant. Observation were recorded on plant height (cm), leaves per plant, length of leaf (cm), width of leaf (cm), neck thickness of bulb (cm), cloves per bulb, weight of clove (g), length of clove (cm), length of bulb (cm), width of clove (cm), diameter of bulb (cm), total soluble solids (%) and bulb yield per plant (g). The magnitude of genotypic correlation was higher than phenotypic correlation for most of the characters. The most important bulb yield per plant had highly significant and positive correlation with clove per bulb and leaves per plant while plant height was significantly and positively correlated with bulb yield per plant indicated that selection for these traits would be effective for the improvement of bulb yield per plant improvement. The maximum positive direct effect on bulb yield per plant was exerted by cloves per bulb, weight of clove, leaf length and length of clove. It is suggested that selection for these traits will directly increase bulb yield per plant.
