Conteúdo: 	The citrus industry is one of the most important agricultural activities in Brazil, and ranks 2nd in the world production (8 million metric tons) and 1 st in concentrated juice export (400 thousand tons). The citrus area (located between 0grau and 30graus south latitude) is calculated at more than 600 thousand ha, with aproximately 150 million trees. One of the most important point to consider is the fact that about 95% of the citrus trees are grafted on Rangpur lime. Taking into account the excellent performance of this rootstock, its almost exclusive use implies some risks since the occurrence of a very serious disease could cause the collapse of the citrus industry similar to that which occurred in 1939-40 with tristeza. Rootstock trials carried out in different citrus areas have shown that a successful rootstock diversification program can be established by the use of other rootstocks besides the Rangpur lime, like Florida and FM rough lemons (C. jambhiri Lush.), C volkameriana pasq. Cleopatra (C. reshni Hort. ex Tan.) and Sunki (C. sunki Hort. ex Tan.) mandarins and others with promising rootstock characteristics.
