Among deciduous tree species peach (Prunus persica (L.) Batsch), from the Near East and introduced by the conquerors in the 15th century to Colombia, is one of the most important fruits in high tropical areas. In highland zones of these regions cultivated varieties have been undergoing a change in gene expression, which has favored the adaptation and implementation of continuous production or cycling systems. In Colombia peach is grown in areas with average temperatures of 13 and 19°C, located between 1.800 and 2.800 m.a.s.l. with monomodal and bimodal rainfall schemes and an average of 1.400 sunshine hours per year. The most cultivated varieties are ' Gold ' and 'Diamante' because of their low chilling hour requirements, while varieties like ' Rubidoux ' or ' Great Jarillo ' are introduced due to its high requirement of chilling hours. The following article seeks to contextualize the importance of phonological and ecophysiological patterns and genetic resources for this important fruit species for the horticulture of the Colombian high altitudinal zones.

Keywords : Ecophysiology; dormancy; floral induction; phenology; varieties.
