A.  aInteraction genotype by season and its influence on the identification of beans with high content of zinc and iron.h[electronic resource]  c2012  aThe mineral contents in common bean seeds are influenced, in addition to genetic variation, by environmental crop conditions, especially by the soil type and chemical composition and by the genotype x environment interaction. This study was carried out to verify if the zinc and iron contents are affected by the crop growing period. Ten lines with high iron and zinc contents and ten with low contents were assessed in three seasons: "wet season" of 2009/2010 (sowing in November); "dry season" of 2010 (sowing in February) and "winter season" of 2010 (sowing in July), in Lavras, Minas Gerais State, Brazil. The experimental design used was randomized blocks with three replications and plots consisting of two rows of two meters, with a spacing of 0.50 m. The seeds harvested were assessed in regard to iron and zinc mineral contents. The greatest contents were observed in the winter season and the smallest ones in the dry season, with sowing in February. It was observed that in the mean of the three harvests, the lines classified as having high iron and zinc content exhibited an iron quantity 11.0% and a zinc quantity 6.8% above those of low content. The lines by seasons interaction occurs. However, its interference in identification of the groups with high and low content of the two nutrients is not great.  aBeans  aIron  aNutritional adequacy  aPlant breeding  aSeasonal growth  aZinc  aFeijão  aFerro  aMelhoramento Genético Vegetal  aPhaseolus Vulgaris  aQualidade  aZinco  aAmbiente de cultivo  aQualidade nutricional1 aABREU, A. de F.
