The adaptability and stability of fifteen pole beans genotypes were evaluated in relation to eight environments. There were statistical differences among genotypes only in three environments. The breeding lines Hav 13, Hav 14, Hav 53 and Hav 56 were among the higher yielding genotypes in all environments. The breeding lines Hav 13, Hav 21, Hav 25, Hav 38, Hav 40, Hav 56, Hav 65 and the cultivar Favorito Ag 480 were stable, while the other ones were unforeseeable according to the Eberhart & Russell method. Genotypes showed a wide adaptation in relation to yield of marketable pods, except Hav 67 adapted to unfavorable environments. The breeding line Hav 13, with cylindrical pods and white seeds was the most advantageous alternative to the standard cultivar Favorito Ag 480.
