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

Abstract

Thirty tomato genotypes were studied for correlation and path co-efficient analysis of fruit yield and yield attributes in tomato (Solanum lycopersicum L.) at Vegetable Research Farm, College of Horticulture, Rajendranagar, SKLTSHU, Hyderabad, Telangana during Rabi, 2015-16. Fruit yield had positive and significant correlation with plant height, average fruit weight, fruit yield per hectare, lycopene and beta carotene. It was observed that with increase in plant height, there was corresponding increase in average fruit weight and fruit yield per hectare. Path coefficient analysis of different yield and yield contributing traits on fruit yield per plant revealed with number of branches per plant, days to first flowering, days to 50% flowering, average fruit weight, number of fruits per plant, fruit yield per hectare, acidity and TSS: Acid ratio exhibited positive direct effects on fruit yield these characters play a major role in recombination breeding and suggested that direct selection based on these traits will be rewarded for crop improvement of tomato.
