ABSTRACT
The correlation and path coefficient studies were conducted for 68 genotypes of tomato at Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, B.H.U., Varanasi during rabi season 2009-10. There are highly significant differences among the genotypes for all the characters studied as per the analysis of variance. Fruit yield had positive and significant correlation with plant height, number of primary branches per plant, number of flower clusters per plant, number of fruits per plant, fruit length, fruit width, pericarp thickness, number of locules per fruit, average fruit weight and fruit yield per plant. It was observed that with increase in plant height, there was corresponding increase in number of primary branches per plant, days to 50 % flowering and number of flower clusters per plant. The association recorded significant improvement in yield. The traits like number of primary branches per plant, number of flower clusters per plant, number of fruits per plant, fruit length, fruit width, pericarp thickness, average fruit weight and number of seeds per fruit exhibited positive direct effects towards yield and these traits also recorded positive significant correlation with yield. This suggested that direct selection based on these traits will be rewarded for crop improvement.
