Research

Charcoal rot caused by Macrophomina phaseolina is a common disease of many crops including common bean and soybean. Resistance to this pathogen in some common bean genotypes was associated with drought tolerance. The authors’ objective was to determine if there were differences in root colonization by M. phaseolina between drought-tolerant and drought-sensitive soybean genotypes.
