Study on correlation and path analysis in Brinjal (Solanum melongena L.)

Abstract

The research experiment was conducted to study correlation and path analysis of total 7 characters (5 quantitative and 2 bio-chemical) among 30 genotypes of brinjal (Solanum melongena L.). The investigation was conducted during Rabi season in the year 2021-22 at Rambhas Farm, Hill Millet Research Station, Navsari Agricultural University, Waghai, The Dangs, Gujarat, India. The correlation study revealed positive and significant correlation of fruit yield per plant with total no. of fruits per plant, plant spread and total soluble solids at both genotypic and phenotypic levels indicating that these traits were mainly influencing the fruit yield in brinjal. Path analysis revealed that no. of fruits per plant and average fruit weight had highest positive direct effect on yield per plant followed by total soluble solids and plant height.
