An important trait for common bean (Phaseolus vulgaris L.) cultivars with Carioca type grain is resistance to Colletotrichum lindemuthianum, which causes anthracnose and a pale corona. The present study was conducted to understand the genetic control of common bean reaction to the fungus and of the corona color, to provide guides to future breeding studies. Genotypes P-45, with brown corona, and EMGOPA 201-Ouro, with yellow corona, are resistant to C. lindemuthianum. Cultivar Carioca is susceptible to anthracnose, but it has desirable grain and corona color. Anthracnose resistance and corona color were studied in the F1 and F2 generations of three populations resulting from crosses of P-45, EMGOPA 201-Ouro, and Carioca. The Carioca x P-45 cross indicated... |
