Developing a model to implement marker-assisted selection for root-knot nematode resistance in common bean.

ABSTRACT: Common bean (Phaseolus vulgaris L.) is a vital crop for direct human consumption, with essential nutrients and valuable protein that provides food security in developing countries. However, its cultivation faces significant threats from Meloidogyne incognita, a root-knot nematode, resulting in considerable yield loss. Developing crop resistance remains a key strategy for mitigating nematode infections. To investigate the genetic architecture of common bean responses to root-knot nematode (specifically, race 3 of M. incognita), we performed controlled crosses between the genotypes "IAC-Tybatã" and "Branquinho" with contrasting resistance. The resulting segregating population (F2) of 333 individuals was genotyped using genotyping-by-sequencing. We used a phenotyping approach, already optimiz
