Host suitability of different common bean varieties in a growth room to the plant-parasitic nematodes Pratylenchus thornei and P. neglectus

What is it about?

Plant parasitic nematodes are major threats to the whole food security. Their hidden nature makes them very difficult to be managed. The root lesion nematodes of the genus Pratylenchus attack very wide host range crops and make significant yield loses. The common bean is one of those crops where the nematodes attack and cause economic yield losses throughout cultivated areas around the world. So far, several management strategies have been employed to control this devastating genus. The most effective management strategy for the root lesion nematodes infections is crop rotation with non-host crops and breeding resistant/tolerant varieties. However, immune parent bean genotypes to the root lesion nematodes are not available for breeding programs; thus, resistant varieties were commonly incorporated as parents.
