A critical component of cultivar development has been the use of "juvenile" gene(s) to improve tropical adaptation. This paper reports the performance of Brazilian and Nigerian germplasms when grown in different seasons, and in diverse locations in Thailand. Brazilian genotypes have slightly longer growth duration than traditional Thai cultivars but have the potential to increase yields of upland wet season crops to a level that makes soybean potentially suitable as sole crops rather than as relay crops. Results observed in Thailand may be applicable in other Southeast Asian production areas.  aBrazil  agenotype  agermplasm  aGenótipo  aGermoplasma  aRendimento  aSoja  aAgricultura tropical  aBrasil  aCultivar  aSoybean  aTropical agricultural  aVariety  aYield1 aCHOTIYANWONG, A.1 aLAOHASIRIWONG, S.1 aNAKIRACKS, P.1 aNEUMAIER, N.1 aPOOKPAKDI, A.1 aPROMDEERAJ, T.1 aSIRICHUMPAN, V.1 aLAWN, R.
