S.  aEnvironmental stratification in Paraná and Santa Catarina to evaluate common bean genotypes.  c2010  aThe purpose of this study was the environmental stratification of the states of Paraná and Santa Catarina for the evaluation of carioca common bean genotypes. The grain yield was evaluated in 20 trials, in a randomized block design with three replications testing 16 genotypes with carioca grain. The environments were stratified by five methodologies: traditional Lin; mean square of the interaction for paired locations, estimate of the percentage of the complex interaction; estimate of Pearson´s correlation, and the Wricke method. Locations identified as uninformative by at least three of the methodologies were excluded. The locations considered uninformative in the respective growing seasons were Roncador (rainy/2003 and dry/2003) and Laranjeiras do Sul (rainy/2004) and no location in the growing season dry/2004. Only Roncador was identified as not very informative in at least two seasons and was therefore eliminated from the evaluation network of Carioca common bean genotypes.  aFeijão  aInteração genética  aMelhoramento genético vegetal  aPhaseolus vulgaris  aCommon bean breeding  aEstratificação ambiental em Santa Catarina  aEstratificação ambiental no Paraná  aGenotype x environment interaction  aInteração genótipos x ambientes  aMelhoramento de feijoeiro comum  aParaná  aPhaseolus vulgaris L  aSanta Catarina1 aMELO, L.
