| Summary: | Improving tomato fruit characteristics is a crucial step to address the decline in production, which is primarily caused by biotic stress and the limited adaptability of existing varieties in lowland areas. This improvement can be achieved through plant breeding programs involving crossbreeding techniques. The primary objective of developing superior varieties is to produce tomatoes with high fruit quality and excellent productivity. The selection criteria were further refined using both principal component analysis (PCA) and path analysis. PCA was employed to identify the primary traits contributing to variability, while path analysis helped establish the strength and direction of relationships between key traits and supporting characteristics. The most significant direct impact will be incorporated into the index value to determine the genotype with the best overall performance. The findings identified 12 F1 tomato breeding lines deemed suitable for progression to the next generation, offering significant potential for enhancing tomato production. This study underscores the effectiveness of targeted breeding strategies. It contributes to developing more sustainable and efficient approaches to tomato cultivation, paving the way for improved productivity and quality in future varieties. |
