Conteúdo: 	Private Soybean Breeding Program in Argentina was started in 1965 by OFPEC. In 1976 two important hybrid crops companies commenced their programs, it is thence when the level of dedication reached special importance. The sanction of the Seed Law was a fundamental factor. Today more than fifteen breeding and/or testing programs are known. Placed, principally, in the central soybean area these companies have had as objective the development of cultivars adapted to actual and potential areas. Each one has different strategies to carry out the work. Conventional methodologies are used, with a clearly offensive manoeuvre with the use of WN, EGT and pest and stress screening methods. This year approximately 20000 progeny rows, 2000 F6 lines and 1500 introduced linesare being rated. The success includes: very highly yield potential cultivars, development of new groups V, resistance to lodging, yield stability, adaptation to new zones and sophisticated management systems, tolerance to stress, superior performance with regard to disease and RKN. Foreigh elite cultivars in other countries do not always fulfilled local requirements. The figures which show the varietal change produced in only seven years, since the release led by the private sector, are eloquent, proving the acceptance of farmers to these novelties. However the general structure of soybean seed commercialization in argentina has not yet reach its maximum such as to permit the massive diffusion of high quality seed of the superior genotypes.
