SCREENING OF FIELD PEA CULTIVARS FOR RESISTANCE TO FUSARIUM ROOT ROT UNDER FIELD CONDITIONS IN ALBERTA

摘要

Field trials were conducted at sites near Vegreville and Namao, Alberta, to evaluate pea cultivars for their resistance to fusarium root rot. At Vegreville, significantly greater disease severities and lower seed yields were observed in Fusarium solari f. sp. pisi-inoculated plots than in noninoculated (control) plots. At both Vegreville and Namao, no significant differences in root rot reaction were observed. All cultivars evaluated were found to be susceptible to this disease. There were considerable variations among cultivars for seed yield in both 1992 and 1993.
