In a previous study, common bean (Phaseolus vulgaris L.) genotypes were selected inthe field for reactions to white mould (WM), caused by Sclerotinia sclerotiorum. Thesegenotypes, along with the resistant control A195, were then evaluated in both fieldand greenhouse (straw test) conditions. The results showed that field trials effec-tively identified high-yielding WM-resistant genotypes for dry-irrigated conditions.Here we challenge the results of this study with new data and methodology by con-ducting six sprinkler-irrigated trials from 2015 to 2017 with five genotype groups (G).Three groups comprised genotypes previously studied: G1, seven partially resistant;G4, two intermediately resistant; and G5, three susceptible. G2 consisted of four linesselected for partial resistance in the current study. The resistant control group, G3,comprised the genotypes A195, G122, Cornell605, and Ouro Branco. WM was absent(one trial), or pressure was either low/moderate (two trials) or moderate/high (threetrials). The average seed yield ranged from 2207 (G3) to 3178 kg/ha (G1). The contrastG1, G2 versus G3 was nonsignificant for incidence and severity index, indicating thatgenotypes selected for resistance in the field were as resistant as the resistant controlgenotypes. Additionally, the groups selected for resistance yielded 43% more andproduced 33% less sclerotia weight compared with the control group. Our resultsreinforce the effectiveness of selecting WM-resistant genotypes using beans origi-nally bred for purposes other than WM-resistance, specifically targeting dry-irrigatedareas. Furthermore, our results suggest that the use of genotypes selected for partialresistance reduces inoculum levels in the soil.
