Studies of correlation between yield and fruit characteristics of (Lycopersicon esculentum Mill.) hybrids and their parental genotypes

Abstract

The correlation between seven quantitative features of tomato (yield per plant, fruit weight, fruit length and width, number of fruits per plant, pericarp thickness, and number of locules per fruit) was studied in seven parental genotypes and 21 F1 hybrids. In both investigated generations there was a significant positive correlation between yield per plant, fruit weight, fruit length and width, and pericarp thickness. A significant negative correlation was recorded between mean fruit mass and number of fruits per plant. A significant positive correlation was found between fruit length and fruit width. Both traits were positively correlated with mean fruit mass. The number of locules per fruit was significantly and positively correlated with fruit weight, fruit length, fruit width and number of fruits per plant, whereas no relation of yield and fruit pericarp thickness with the number of locules was recorded.
