The objective of this review was to mention the main results of research and the perspectives to increase minerals (calcium, iron and zinc), sulfur amino acids (methionine and cystine) and dietary fiber content in common beans by genetic breeding. The traits that show nutritional quality to common beans have genetic variability, environment and genotype x environment interaction. Maternal effect was observed in the expression of calcium, iron and protein content in common beans and this has a direct effect in the selection and in the conduction of the segregant populations obtained by plant breeding programs. High estimates of heritability in narrow sense were gotten for calcium, iron and zinc content, presenting acceptance for selection. The increase of minerals, amino acids and dietary fiber content is possible for plant breeding. The common bean germoplasm availability with nutritional quality is very important to human nutrition and to agriculture.
