Resumo

The purpose of this research was to survey Macrophomina phaseolina incidences on snap bean from the bank of snap bean germplasm at the Universidade Estadual do Norte Fluminense Darcy Ribeiro, so as to start a breeding program aiming at obtaining resistant cultivars. Twenty-nine accesses (F10 lines) from the snap bean germplasm bank regarding the reaction to Macrophomina phaseolinawere assessed. The evaluation was performed 20 days after inoculation, and the response of plants to infection was estimated by a graded scale from zero to five. Five promising accesses were chosen to be considered as genitors in the breeding program in view of resistance, which are related as follows: UENF 7-6-6, UENF 7-10-10, UENF 9-4-14, UENF 14-6-26, and UENF 14-22-102.
