In 1985 and 1986, respectively, 16 and 36 cultivars of peppers were grown in yield tests at Isabela, P. R., in a randomized complete block design with four replicates. Each replicate was a 3.7-m (12-ft) row with 12 plants. Because of Fusarium infestation replanting was needed in 1985 and two replicates were lost in 1986. There were no significant differences among cultivars in standcount response to Fusarium. There were significant yield differences both years. The highest yielders tended to be, but were not exclusively, hybrids. Frying (Cubanelle) and pimento types did very well. Among the best standard cultivars were "Staddon's Select", "Jupiter", "Super Stuff' and "Blanco del País". In at least some cases a grower can earn more per area with the right open-pollinated cultivar than with the substantially more expensive hybrids.
