Conteúdo: | Since 1977, Embrapa Uva e Vinho has been leading a breeding program, aiming to develop grape cultivars for different purposes as table grapes and also for wine and juice. The objectives of this program can be summarized as the development of grape cultivars adapted to different production regions, including tropical ones, presenting tolerance to the main grape diseases and pests occurring in Brazil and quality for different purposes. About 3,000 hybrids from crossings between several Vitis species, including wild tropical ones, are evaluated each year. Selected individuals are multiplied and evaluated for 3-4 years. Then, promising materials are propagated and evaluated in larger plots for more 3-4 years. This step can include sensory analysis of table grapes, juice or microvinifications, depending on the goal. Advanced selections are then tested on commercial fields, for about 2 years. New cultivars are released only when this decision is also supported by growers. As results, 14 new Brazilian grape cultivars were released in recent years, contributing to several segments of the grape production chain. Currently, about 300 table and processing grape selections are under evaluation and five new advanced selections are under validation. These point toward the perspective of development and release of new Brazilian grapes in the next few years.
