Comparative Genome-Wide-Association Mapping Identifies Common Loci Controlling Root System Architecture and Resistance to in Pea.

Combining plant genetic resistance with architectural traits that are unfavorable to disease development is a promising strategy for reducing epidemics. However, few studies have identified root system architecture (RSA) traits with the potential to limit root disease development. Pea is a major cultivated legume worldwide and has a wide level of natural genetic variability for plant architecture.
