Forty eigth years of grape breeding in São Paulo, Brazil

Abstract

The importance of table grape cultivation in São Paulo State, Brazil, is increasing in the last years, which is demonstrated by its acreage increase. Demands for technology improvements have followed, specially in respect to the development of new cultivars that can produce high quality grapes for exportation or internal markets purposes. Since the beginning of the grape breeding program at the Instituto Agronômico de Campinas (IAC) in 1943, no study was carried out on the parents used in crossings. In this study, hundreds of crossings, parents, as well as resulting progenies and their genealogical (pedigree) relationship were evaluated. According to the analysed data and parameters used we may consider as preferential the following cultivars: 'Itália', 'Patrícia', 'Soraya', 'Cardinal','Roberta', 'Maria Rosa', 'Carolina', 'Moscatel de Hamburgo', 'Lígia', 'Angelina', 'Marília', 'Alphonse Lavallée', 'Traviú', 'Ezequiel', 'Grão Mogol', 'Yole', 'Geni', 'A Dona', 'Aurora', 'Piratininga', 'Maria', 'Iracema'.
