Reaction of common bean genotypes to plant parasitic nematodes

Abstract

Among the efficient strategies to manage plant parasitic nematodes, the use of resistant cultivars stands out for being frequently the easiest and least expensive approach that can be adopted by farmers. However, for the common bean, in Brazil, few sources of resistance have been identified so far. This study aimed to assess the reaction of 81 common bean genotypes to the most abundant and harmful plant parasitic nematode species in Brazilian crop fields. Genotypes resistant to all tested nematodes were observed: 7 to Heterodera glycines, 2 to Pratylenchus brachyurus, 15 to Meloidogyne incognitaand 8 to M. javanica.
