Abstract
Brazil has a very rich and diversified range of native fruit species, mainly in the North region and the savanna area.
Temperate fruit species are present in a more restricted area, but are numerous and important.
The most spread wild species in Southern Brazil, belong to the following families: Myrtaceae, Annonaceae, Berberidaceae, Rosaceae, Solanaceae, Passifloraceae, Palmae, Caricaceae, Leguminosae and Bromeliaceae.
Temperate fruit species were introduced centuries ago, and include peaches, nectarines, plums, apples, pears, which are now becoming an emergent and important industry in Brazil.
There are several well adapted and productive selections, most of them derived from seedlings of unknown origin in home gardens, which are a worthy source of diversity.
The Brazilian temperate fruits research system comprises Embrapa, State institutions and universities, which are integrated into a National Resources and Biotechnology Research Center-CENARGEN, in Brasilia-DF. The temperate fruit genetic resources conservation comprises 6 field regional centers, which include apples, pears, peaches, plums, grapes and native temperate fruit species.
This system has established field plots with at least 100 species and more than 6000 accessions.
Morphological and molecular characterization, and evaluation of the most important temperate fruits are in progress in the active genebanks.
EMBRAPA-CPACT has an intensive breeding program with peaches, and to a less extent in plums, pears, apples, blackberries and strawberries.
Several seedlings have been introduced to the Central Collection and were used to develop several new cultivars.
EPAGRI in Santa Catarina State has on intensive apple breeding program, and IAPAR in Paraná State has plum and apple breeding programs, while UNESP/FAC and IAC, in São Paulo State is breeding temperate fruit species searching for adaptation to subtropical climes and several new varieties have been developed.
In this paper, the number of accessions per species, and the location where the collections are maintained are presented.
The germplasm documentation system distributes information through the SIBRARGEN (Brazilian Genetic Resources Information System), and it will soon be available through the Internet.
