Peach (Prunus persica L. Batsch), has its origin in China and is considered a typical fruit of temperate climates. For centuries it has been cultivated at high latitudes, between 30° and 50° north and south, where generally occurs 500 to 2,000 hours of temperature below 7.2 °C per cycle. When it was introduced in low latitudes, such as 26 ± 2 º S, the peach tree had to be adapted to the prevailing subtropical climate. The adaptability of peach at different environmental conditions worldwide is due to genetic selection of improved cultivars, both with low or high chilling requirement. In Brazil, more precisely in the state of Santa Catarina, the Institute for Agricultural Research (Epagri) is developing a breeding program to achieve cultivars adapted to humid subtropical climate at Urussanga Research Station. Features such as low chilling demand, fruit quality and productivity have been the subject for over 10 years of breeding. Parent varieties are from the Campinas Agronomic Institute (IAC), Brazil, the Brazilian Agricultural Research Enterprise (Embrapa), Brazil, and the University of Florida. Among the strategies of the improvement program, Epagri includes the participatory research at farms with a history of peach production. Results show several selections with high productivity, large fruit size, low acidity, firm and white pulp. The program also aims to select clones with maturity between 01 October and 20 December, which is out of the harvest season in temperate regions. Some genotypes already selected presented cycles between 70 and 120 days from flowering to harvest. MenosPeach (Prunus persica L.
