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 that the Mex.2 allele, which conditions resistance to the pathogen, is linked with a recombination frequency of 0.0604 ± 0.0232 to one of the alleles which determines the dark brown corona color. The EMGOPA 201-Ouro x Carioca cross revealed that the resistance allele of EMGOPA 201-Ouro was independent from the alleles which determine the yellow corona. These resistance alleles were also determined to be independent according to EMGOPA 201-Ouro x P-45 cross results.

The objective of this work was to evaluate the efficiency of nitrogen fixing inoculum associated with Co + Mo leaf spray on the common bean grain yield and grain nutrients, cv. FT Nobre. Three dosages of the inoculant (0, 200 and 400 g/50 kg seeds), combined with four Co + Mo leaf spray levels (T0=0,0; T1=4.9,49; T2=7.3,73; and T3=9.7,97 g ha-1 of Co and Mo, respectively) were tested. The grain yield with the use of the inoculant (400 g / 5O kg seed-1) associated with the higher level of Co+Mo (T2 and T3) was very similar to the mineral nitrogen condition fertilizer recommended for the bean (70 kg ha-1 of N). With the increased inoculant dosage, an increase of the protein content and of P and Mg in the grain was also observed. The results indicated that the mineral nitrogen source could be replaced by inoculation of the seeds with Rhizobium tropici combined with Co + Mo leaf spray.
