Abstract:
Tomato is one of the most significant vegetable crops, which provides several important dietary components. The present study aimed to investigate association analysis for yield and yield-related traits and quality traits in tomatoes. For this purpose, fifteen tomato genotypes were evaluated in the field of AICRP on vegetable crops, Horticultural Research cum Instructional Farm, Department of Vegetable Sciences, Indira Gandhi Krishi Vishwavidyalaya, Raipur during 2019-20 in randomized complete block design with three-replication to study the association analysis between relevant traits. The genotypic correlation analysis revealed that the yield per plant was significantly and positively associated with plant height, number of primary branches, number of secondary branches, days to first flowering, flowers per cluster, fruit weight, polar diameter, equatorial diameter, number of fruits per cluster and pericarp thickness, pulp juice ratio, yield per plot. Path analysis was performed to know the direct and indirect effects of related traits on yield and fruit yield was used as a dependent variable while other characters are considered as independent variables. The findings depicted that the plant height, primary branches, days to first flowering, days to 50% flowering, flowers per cluster, polar diameter, fruit weight, calyx length TSS pericarp thickness, and acidity showed that it was a positive direct effect on the yield per hectare. Hence, it may be suggested that these are the most effective and reliable parameters for genetic improvement in the fruit yield of tomato genotypes. The genotypes in this experiment can be used as parents for future studies on hybridization programme to enhance the yield and quality of tomato.
