ABSTRACT
The purpose of this research was to elucidate the genetic control of orange corona color in carioca common beans (Phaseolus vulgaris). We made four crosses between carioca group cultivars that differed in respect to the presence or absence of an orange hilum corona color. The F2, F3, F1BC11, F1BC21, F2BC11 and F2BC21 phenotypic segregations were evaluated with a chi-square test which fitted with the hypothesis that one gene with a dominant allele is responsible for the orange corona color. All generations resulting from the four different crosses showed segregation patterns which agreed with the expected proportions. Our results show that the dominant G allele controls orange corona color in the carioca bean group.
