Abstract:
A comprehensive analysis involving correlation and path coefficients was conducted on a collection of thirty-three tomato genotypes. The objective of this study was to examine the nature and strength of relationship between the yield of tomato plants and the various contributing factors. These genotypes were cultivated using a randomized block design in two replicates at the PG Research Block, located within a naturally ventilated polyhouse at the College of Horticulture, Rajendranagar, Hyderabad, during the year 2022-23 Rabi season. Observations were recorded for ten distinct parameters related to tomato fruit, yield and quality traits. The correlation coefficients demonstrated a significantly positive association with fruit yield per plant at both the genotypic and phenotypic levels for several factors, including the fruit length, fruit diameter and average fruit weight. Furthermore, there was a positive significant association at the genotypic level for pericarp thickness, ascorbic acid content and shelf life while negative correlation with total soluble solids. The results obtained from the path analysis unveiled that the fruit diameter, total soluble solids exerted a direct and positive influence on fruit yield per plant both at genotypic and phenotypic level whereas fruit length and number of locules per fruit exerted a direct and negative influence.
