However, most of the recommended varieties are susceptible to diseases and mineral stresses, and subject of breeding programmes for the crop. Laboratory techniques for screening progenies by non-destructive evaluation can be used in both cases, when large populations are needed. Testing is quite laborious and the transplant of selected seedlings may not be feasible, if data are not analyzed prior to selection. The method described allows sotrage of selected individuals in cold temperature until all families from crosses have been tested and analyzed. Stored seedlings were kept for two and four weeks, at 5C and 95% relative moisture, beforetransplanted and evaluated at maturity. It has been effective to recover normal plants from long-term cold stored seedlings and may be successfully used as a tool in soybean breeding.  apopulation  aCruzamento  aGlycine Max  aPopulação  aResistência  aStress  aVariedade  aCross  aEstresse  aResistance  aTolerance  aTolerancia  aVariety  tPesquisa Agropecuária Brasileira, Brasília, DFgv. 30, n. 8, p. 1075-1077, ago. 1995.
