Abstract
The current study was aimed at evaluating the stability of tomato yield and yield-contributing characteristics during three sowing intervals (February, March, and April) under high-temperature regimes, Pooled analysis of variance was performed on twenty-five genotypes, including eight parents, fifteen hybrids, and two checks, for seventeen agronomic traits. Except for plant height, ANOVA findings have revealed substantial differences among tomato genotypes, with environmental conditions playing a major role on genotype performance. The genotypes differed significantly in terms of days to 50% flowering, number of flowers per cluster, and fruit length, indicating significant variability among growing seasons. Furthermore, root length showed significant genotype x environment interactions, whereas the remaining variables are found non-significant. Among the three sowing intervals, February sowing (1st interval) was found to be the most beneficial environment for tomato growth, yield, and quality features, with the highest positive environmental indices for the majority of growth, yield, and quality contributing traits. In contrast, the April sowing period (3rd interval) was found to be most unfavorable, with the highest negative environmental indices for the traits studied. This study underlined the significant influence of environmental factors on the performance of tomato genotypes, in terms of multiple yield and yield-contributing attributes. The findings emphasize the importance of choosing the optimum sowing interval, with February as the most favorable season for cultivating tomatoes in the present study location under high-temperature conditions. These findings would help to guide the decision-making process in similar agro-climatic regions to improve the tomato output and quality.
