Abstract

The peach (Prunus persica) and nectarine (P. persica var. nuscipersica) are species from China that show growing since antiquity. The first plantings in Brazil began with the arrival of European settlers. As economic interest orchards, the culture Peach settled in São Paulo in the 30s, primarily in mountainous regions of the state. Despite its characteristics of temperate fruit's trees, has been cultivated in subtropical areas through the development of cultivars with lower chilling requirement to break dormancy required for flowering. The first selections were obtained by producers and prompted the development of the industry in the first decades of cultivation. From the 30s the Agronomic Institute (IAC) initiated introductions of varieties developed in Florida (USA) and it was the basis of the breeding program. Until today were selected 32 varieties of peaches and four nectarines by Agronomic Institute, in addition to materials introduced and adapted to São Paulo State climatic conditions. Due to the economic importance of São Paulo's agribusiness, the breeding program of peaches and nectarines keeps jobs characterization and development of new varieties for the main producing areas of the São Paulo State. Thus, this project aims to select new varieties of peaches and nectarines for producers and consumers. (AU)
