Tomato Summer Sun

The Genetic Architecture of «Summer Sun»

The Israeli breeding program at Hazera offers a professional perspective on the cherry tomato segment. «Summer Sun» is an indeterminate hybrid engineered for prolonged harvesting cycles in both protected and open-field environments. The key advantage of this tomato lies in the synergy between fruit firmness and a well-balanced biochemical composition, resulting in superior organoleptic properties.

Biological Defense as a Yield Foundation

The hybrid’s resistance to pathogens is a result of selective breeding designed to reduce the reliance on chemical fungicide applications:

• Tobacco Mosaic Virus (TMV): A genetic block prevents viral infiltration, ensuring the plant remains healthy throughout the entire growing season.
• Fusarium Wilt (Fol): A robust root system allows the plant to maintain turgor pressure even under high-temperature stress inside greenhouses.
• Verticillium Wilt (Va/Vd): Prevents premature leaf senescence, which is critical for maximizing cluster development.

Technical Specifications of the Fruit

In commercial production, «Summer Sun» demonstrates exceptional uniformity. The round fruits, weighing 20–40 grams, feature a vibrant yellow color that is highly sought after in retail markets. With a maturation period of up to 90 days, it is classified as a mid-season hybrid capable of delivering stable yields when nutrient management and irrigation are optimized. The indeterminate growth habit requires staking and pruning, allowing producers to effectively utilize vertical greenhouse space and increase output per square meter.
