Reaction of common bean genotypes to Heterodera glycines

Abstract

The soybean cyst nematode (Heterodera glycines) may result in a significant economic impact on bean cultivation. This study aimed to evaluate the reaction of 55 common bean genotypes from the Embrapa Arroz e Feijão core collection to the race 3/HG type 0 of H. glycines. Among the genotypes evaluated, 34 were considered resistant to the cyst nematode, and, in addition to showing a lower population of females in the roots, also reduced the fecundity of H. glycines.
