Several varieties of Melilotus alba and M. officinalis were evaluated in the spring of 4 years for their resistance to Plenodomus meliloti. Survival and yield were a reflection of resistance which was related to lesioning of roots and formation of pycnidia. Survival was correlated with lesioning of roots (r = − 0.73) and pycnidial formation (r = − 0.67). There was evidence that the reaction of a variety could vary depending on the geographic origin of the seed. A new host, Lotus corniculatus, is reported.
