Abstract: In the present investigation, at the Horticultural Research Centre, Department of Horticulture, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (UP), during the year of 2015-2016 on “Study the estimates of correlation coefficient for genotypic level among different character’s and correlation between yield and yield contributing traits. All twenty-two genotypes were grown in randomized block design with 3 replications with row to row and plant to plant spacing of 30 cm and 20 cm, respectively during 2015-16. High heritability coupled with high genetic advance was observed for length of longest leaf, number of bulbs per plant and number of bulblets per plant. Bulb yield exhibited significant and positive association with days taken to sprouting, plant height, length of longest leaf, width of longest leaf, days required for visibility of first spike, days taken to opening of first flower, number of florets per spike, number of spikes per bulb, number of bulbs per plant, number of bulblets per plant, yield of bulb per plant, diameter of bulb, yield of bulb and bulblets per plant at both genotypic and phenotypic level. This might be due to linkage of genes determining these characters. Thus, it can be inferred that selection based on any one of these characters either alone or in combination, will help to identifying high yielding genotypes. Genotypic correlation was of higher magnitude as compare to their corresponding phenotypic correlation in most of the character combination, thereby, suggesting strong inherent association between genotypic and phenotypic level.
