Abstract

For twenty yield-contributing traits, correlations and path coefficients were examined in seven tomato (Solanum lycopersicum L.) genotypes. The interrelationship between the analysed features was discovered using the correlation coefficients. Average fruit weight, fruit yield per plant, equatorial fruit diameter, polar fruit diameter, total phenolic content, and days to 50% flowering all showed strong positive correlations with total fruit yield. However, the first day of fruit set was very significantly negatively correlated with total fruit yield. Whereas, lycopene content had high significant and positive correlation with total phenolics content, TSS content and total antioxidant capacity but negative correlation with titrable acidity. The total fruit yield had the highest positive direct effect in the path coefficient analysis, followed by the number of fruit per plant, the number of locules per fruit, the days to 50% flowering, and the number of primary branches per plant, all of which both positively correlated with and directly affected the yield.

Conclusion

The link between average fruit weight, fruit output per plant, equatorial fruit diameter, polar fruit diameter, and total phenolic content was significantly positive, as were the days to 50% flowering, while days to first fruit set have a strong, negative relationship with overall fruit production. On the other hand, lycopene content has high significant and positive correlation with total phenolics content, TSS content and total antioxidant capacity but negative correlation with titrable acidity. In path coefficient analysis the highest positive direct effect was noted in total fruit yield followed by number of fruit per plant, number of locules per fruit, days to 50% flowering and primary branches per plant both had a favourable association with yield and a direct impact on it. Thus, these characteristics can be employed as selection indices in tomato breeding to increase yield.
