Evaluation of the Milionário bean cultivar as bridge-crossing between ‘Ruda’ and ‘Jalo EEP 558’

Abstract

This study evaluated the efficiency of the cultivar Milionário as bridge to incorporate alleles of resistance to angular leaf spot of the Andean cultivar Jalo EEP 558 into the Mesoamerican cultivar Rudd. According to the observed results, ‘Miliondrio’ cannot be used as bridge in this cross since the resultant hybrid ofthe cross with ‘Jalo EEP 558° presents a characteristic incompatibility reaction. This result is not in line with previously published results, which had Suggested the Miliondrio cultivar as bridge.
