Abstract

Abstract This study aimed to evaluate the resistance of three common bean genotypes (BRS Estilo, A211 and Mortiño) to the Fusarium oxysporum f. sp. phaseoli using different inoculation methods such as the root-dip, the colonized toothpick, and the agar-based disk-diffusion. After 35 days of inoculation, the disease severity was assessed by vascular discoloration on the stem of the plants by two methods: using a scoring scale and measuring the length of the discoloration with the aid of a millimeter ruler (cm). Results showed that the root-dip was the most effective inoculation method. As for the method of assessing the disease severity, the scoring scale was the best one, in addition to being easier for evaluating large amounts of common bean lines. (AU)
