Abstract:
The present study was undertaken at Vegetable Research Center, G.B. Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar (U.K.) during September- December, 2015. Fifty seven genotypes of cauliflower were grown in Augmented Block Design II including five checks which were arranged in four blocks with eighteen genotypes in each block inclusive of five checks. The study was primarily focused on assessing correlation coefficient and path coefficient analysis. The genotypic correlation coefficient was higher than the corresponding phenotypic correlation coefficient for all the parameters. Estimates of phenotypic and genotypic correlation revealed curd yield per hectare to be highly positive and significantly correlated with marketable curd weight, net curd weight, curd diameter, number of leaves per plant and gross plant weight. Path coefficient analysis revealed net curd weight having a high positive direct effect towards the total yield while harvest index exerting a negative direct effect on curd yield per hectare.
