Conteúdo: 	The development of improved common bean (Phaseolus vulgaris L.) varieties one should consider not only grain production but also other traits such as grain type, growth habit and disease resistance. Based on these traits, a population of 154 recombinant inbred lines (RIL's) was developed from the cross between common bean cultivars Rudá and Ouro Negro aiming to establish a permanent population for mapping purposes and also to select promising lines to be evaluated in preliminary tests at EMBRAPA - Arroz e Feijão. Mean yield per plant, seed color and growth habit were determined for the 154 RILs in a randomized complete block design with additional commercial varieties as controls. Resistance of the RILs were also evaluated under controlled conditions for seven races of Uromyces appendiculatus, three races of Colletotrichum lindermuthianum and four races of Phaeoisariopsis griseola, the causative agents for rust, anthracnose, and angular leaf spot, respectively. Ten RILs were selected, two with "carioca" seed type, four with black seeds and four with beige seeds. All selected RILs presented type IIB growth habit ad were resistant to the all U. appendiculatus and C. lindemuthianum races used in this work. RILs numbered 38 and 113 were also resistant to the all P. griseola races. The selected RILs may give rise to common bean varieties with "carioca" type or beige seeds, bearing important disease resistance genes, and also to productive black seeded varieties, resistant to several diseases and with growth habit type IIb.
