The sweet and orange-fleshed fruits have negligible pungency of circa 170 SHU (Scoville Heat Unit) and high content of vitamin C (205 mg 100 g of fruit-1). ‘BRS Tui’ was developed to meet both the fresh fruit market and the processing industries, particularly for production of pepper preserves, in addition to the potential use in many gourmet products such as sauces, jellies, flavored oils and vinegars, or even the ornamental pepper niche. The orange-fleshed fruit differentiates ‘BRS Tui’ from the other Biquinho pepper cultivars, with great potential to occupy new market niches. SEED MAINTENANCE AND DISTRIBUTION Embrapa Hortaliças will provide seeds of ‘BRS Tui’ under contract to interested seed-producing companies.
