S.  aThe citrus industry and its germplasm banks in Brazil .  c2010  aT02.242, pdf.  aThe citrus industry in Brazil represents a large component of the economic and social sectors of the country. The cultivated area almost 1 million hectares and the production of fruit surpassing 20 million tons are responsibles for the brazilian leadership in the world citrus production and frozen concentrated orange juice. The purpose of this paper is to analyse the status of the citriculture in the producing states, the utilization of scion and rootstocks and the available germplasm. Although this leadership some threats to the sustainability of the citrus industry must be considered: the high concentration (around 80% of the national production) in one State (São Paulo) where more than 90% is destined to orange juice processing; the predominance of the combination of `Pera’ orange on `Rangpur` lime and, above of all, the prevalence of diseases, mainly the virotic and the bacterial ones, specially those transmitted by insects. Taking these aspects into consideration, one can appreciate the importance of germplasm banks established in the country for support and contribution to the diversification of the citrus industry. According to the Embrapa Genetic Resources Centre there are three Citrus Active Germplasm Banks (CAGB) in Brazil: first at the Sylvio Moreira Center, Cordeiropolis, São Paulo (2,000 accessions); second at Cassava and Tropical Fruit Crops, Cruz das Almas, Bahia (800 accessions) and third at Fruit Crops Research Centre, Taquari, Rio Grande do Sul) (400 accessions). Given to the occurrence of HLB (ex-greening) in São Paulo and citrus canker in Rio Grande do Sul, the only CAGB free of these and other harmful diseases, up to date is that located in Bahia. Due to this comparative advantage efforts are being made to index this germplasm, clean it if necessary and mantain it under screen house. The goal is to mantain up to 1200 plant accessions in 45.0 l containers spaced 2.00 × 2.00 m under cover, which will demand one hectare of land area.  aDoença de Planta  aFruta Cítrica  aMelhoramento Genético Vegetal  aBAG  aGermoplasm  aOrange1 aSOUZA, A. da S.1 aSOARES FILHO, W. dos S.1 aGESTEIRA, A. da S.  tIn: INTERNATIONAL HORTICULTURAL CONGRESS, 28., 2010, Lisboa.
