Description:	The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is one of the most important diseases in Brazil that causes losses in practically all Brazilian growing regions. Breeding for SCN resistance has become a priority for all soybean breeding programs, since genetic resistance is probably the only practical SCN control method. The oligogenic basis of resistance in soybean and the genetic diversity of nematode populations that can suffer selection pressure from resistant varieties are the challenges to be managed by researchers. The most common strategy to introduce SCN resistance in Brazil has been the selection of lines derived from populations resulting from crosses including adapted genotypes and North-American cultivars with resistance derived from ?Peking? (?Pickett?, ?Sharkey?, ?Centennial?, ?Padre?, ?Forrest?, ?Gordon?, among others) and/or from PIs 88788 (?Bedford?, ?Linford?, ?Fayette?, ?Leflore?, etc), 90763 (?Cordell?) and 437654 (?Hartwig?). Resistance of more than 60 Brazilian soybean cultivars was developed from few sources that normally provide resistance to race 3 or to races 1 and 3. A few varieties adapted to Central Brazil, the savannah area, have resistance to most races, except races 4+ and 14+ which are specific to Brazil and broke the resistance from ?Hartwig?. There are very few resistant varieties adapted to the Southern Region, where the demand for new resistant varieties is likely to increase in the near future. Selection assisted by molecular markers for SCN resistance is already a routine in some breeding programs and will become absolutely necessary to improve the selection efficiency and increase the genetic gains for this trait.
