Evaluation of Tomato Promising Hybrids Productivity Under Different Environmental Conditions
Year: 2024
Type: article
Abstract: The impact of successive climate changes has become a phenomenon that requires continuous evaluation and selection of suitable genotypes in terms of quality and productivity for most crops around the world, and this is one of the objectives of plant breeding and conservation program of Desert Research Center. Therefore, this study aimed to evaluate 60 tomato (Solanum lycopersicum) hybrids under six environments (three locations during two agricultural seasons; 2022 and 2023). The results indicated that, the variance of genotypes (G), environments (E), genotype x environment and G x E (linear) components were significant for mean yield weight per plant. According to Eberhart and Russell model, the data indicated the selection of some distinctive hybrids according to the high average yield, the regression coefficient close to one, and the non-significant deviation from the regression, and they were the most stable across different environments. In general, and according to the results, G16, G18, G28 and G29 were distinguished in terms of stability and yield across different environments. Stability of the performance of tested tomato genotypes is a major goal of breeding programs that keep pace with changing environmental conditions.
