摘要：

The pathogenicity of 45 isolates of A. pinodes, A. pisi and P. medicaginis var. pinodella collected in South Australia was examined on selected pea [Pisum sativum and P. sativum var. arvense] lines. Twenty-six isolates of A. pinodes were differentiated into 15 pathotypes, 15 of A. pisi were differentiated into 13 pathotypes, and 4 of P. medicaginis var. pinodella into 1 pathotype. Adequate sources of resistance were identified against all the pathotypes except pathotypes 1 of A. pinodes and A. pisi. The necessity to breed for broadly based resistance to Ascochyta spp. is discussed.
