Correlation and path coefficient analysis in tomato (Solanum lycopersicum L.)

The field experiment of this investigation was conducted at Vegetable Research Farm, Kalyanpur, Department of Vegetable Science, C. S. Azad University of Agriculture & Technology, Kanpur during rabi season 2019-20. The experimental materials consisted of forty (40) genotypes of tomato. These genotypes were selected out of the germplasm collection being maintained at Department of Vegetable Science, C.S. Azad University of Agriculture & Technology, Kanpur. The investigation was statistically laid out in the field adopting Randomized Block Design (RBD) with forty (40) genotypes in replicated thrice. Positively and highly significant correlation showed by number of fruit per plant with fruit weight per plant and days to flowering with days to maturity. Positively significant correlation showed by plant height with fruit weight per plant and days to maturity with number of fruit cluster and fruit width. Path coefficient analysis indicated that the number of fruit per plant, fruit width, plant height, fruit length, days to maturity showed maximum positive direct effect on yield and days to flowering showed minimum positive direct on yield. Number of branch per plant, number of locule per fruit showed negative direct effect on yield. Number of locule per fruit show maximum negative direct effect on yield and Number of branch per plant showed minimum negative direct effect on yield.
