Correlation Coefficient and Path Analysis Studies on Various Horticultural Attributes of Cauliflower (Brassica oleracea Var. Botrytis)

Abstract

Background: Cauliflower is one of the foremost vegetable among all Cole crops. It contains an incredible amount of essential nutrients and vitamins. Being the second most important crop among all Cole crops, cauliflower contributes to overall vegetable productivity. The principal objective of this study is to evaluate the different genotypes on the basis of horticultural traits, so that can be further utilized in crop improvement programs. Methods: The present experimentation was initiated with fifteen diverse cauliflower genotypes. The trial was set up with a RCBD along with 3 replications, during the year of 2018-2019 at Lovely Professional University, Phagwara (Punjab). Result: Correlation analysis showed that yield of curd per hectare exhibited highest positive and significant correlation with leaf width, curd diameter, depth of curd, stalk length of plant, leaf length, net curd weight, days to curd initiation, gross plant weight, harvest index, marketable curd weight and days to curd maturity. Highest positive and direct effect was observed on yield of curd with marketable curd weight, leaf width, net curd weight, gross plant weight, length of plant stalk, harvest index, days to curd maturity, days to curd initiation, curd depth, Leaf lamina length, curd index and curd diameter.
