Abstract:

Sixteen superior recombinant inbred lines (RILs) and two commercial varieties viz., Anagha and ArkaVikas were evaluated for growth, yield and quality parameters in tomato during rabi 2019-2020 in randomized block design with three replications. Correlation analysis revealed that equatorial fruit diameter (cm), polar fruit diameter (cm), average fruit weight (g), number of locules per fruit and pericarp thickness (mm) exhibited significant and positive association with fruit yield per plant (kg) at both genotypic and phenotypic level. Path coefficient analysis revealed that average fruit weight had very high direct positive effect on fruit yield per plant followed by equatorial fruit diameter. Hence, direct selection for these traits would be rewarding for improving fruit yield per plant.
