Aiming at the knowledge of yielding capacity of dry bean lines resistant to the anthracnose agent and belonging to the Rosinha and Roxinho groups, sixteen trials in randomized complete-block design were carried out in the Main Experimental Station of Campinas in the rainy season of 1977 and 1978, having 'Rosinha G2' and 'Roxo-Minas' as controls. None of the Rosinha lines outyielded 'Rosinha G2', at the 5% level although high mean yields, around 1,830kg/ha, were observed for some of them in the pathogen absence. On the other hand, 8 lines of 'Roxinho' group were superior to the control 'Roxo-Minas' at the 5% level having mean yields ranging from 1,490 to 2,027 kg/ha, without the presence of the pathogen. The interaction line x year was not significant but the year effect was. The best lines will be included in the regional trials and seeds of some of them increased in large quantities for releasing to the growers of Campinas region.
