P.  aGenetic improvement of soybean from populations developed by alternative recurrent selection strategies.  aAmes: Iowa State Universityc1985  a116 p.  aTese Doutorado.  aTwo aspects of a recurrent selection program that can be manipulated are the extensiveness of testing used to identify superior individuals and the number of intermating generations conducted among the superior individuals to form a population for the next cycle of selection. The objective of the research was to compare the performance of soybean [Glycine max (L.) Merrill] lines derived from populations developed by recurrent selection for seed yield with one or two stages of replicated yield testing to identify superior individuals and one or three generations of intermating among the selected parents.  aMelhoramento  aPopulação  aSeleção  aSoja  aAlternativa  aMelhoramento genetico
