Resumen
Off-season vegetables become expensive so new technological systems are required to grow cultivars well adapted to climatic conditions throughout the year. Accordingly, a trial was performed to test 12 tomato F1 commercial hybrids in a Cuban sheltered installation based on the ?umbrella? effect recommended for tropical conditions. The main goal of the trial was to study cultivar productivity and adaptation traits before offering recommendations to growers. The ´37242´ (7.4 kg plant-1) and ´Setcopa´ (7.1 kg ha-1) F1 hybrids showed the highest marketable yields, commercialized at 93% and 87%, respectively. The performance of the ´37242´ was notable; its high fruit set (87%) during the hot and wet season showed its adaptation to the local conditions. The studied cultivars were asymptomatic to tomato yellow leaf curl virus (TYLCV), despite its high prevalence in the area
