Tomato yellow leaf curl virus (TYLCV) devastates tomato crops worldwide, yet finding varieties that resist the disease while maintaining high yields remains challenging. We tested 25 tomato genotypes in real-world conditions to identify the best performers. We discovered several promising candidates using advanced statistical methods, particularly genotype G13, which showed strong yields (8.8 kg per plant) with 8.67 fruits per cluster and maintained healthy growth under disease pressure. Other standouts (G2, G3, G10, G11) demonstrated moderate resistance, with only 12.5–19.4% disease severity. Key findings revealed that branch number and fruit clusters directly boost yield, a valuable insight for breeders. The high heritability of these traits means growers can reliably select for them in future seasons. Our results provide practical solutions: the identified genotypes offer a genetic toolkit for developing tomatoes that thrive in TYLCV-prone areas without sacrificing productivity. This work bridges the critical gap between disease resistance and yield potential, giving farmers actionable options to protect their harvests.
