L. de  aGrain yield and seed quality of soybean selected for high protein content.  c2004  aTítulo em português: Produtividade de grãos e qualidade de sementes de soja selecionada para alto teor de proteína.  aThe objective of this work was to evaluate the effects of selection for high protein on seed physiological quality and grain yield of soybean. Four populations of BC1F4 and four of F4, each from a cross between a commercial variety and a line bearing high protein seeds, were used. The high protein content selection has a tendency to affect negatively the seed physiological quality. Estimates of correlation coefficients between protein content and grain yield were mostly negative but varied among populations. It is possible to obtain lines with high protein content, keeping the grain yield and the seed physiological quality of their respective recurrent progenitors.  aplant breeding  aprotein content  aGlycine Max  amelhoramento de plantas  aprogenitores  aprogenitors  ateor em proteína1 aSEDIYAMA, C.
