Black spot is a devastating disease on field pea caused by a complex of pathogens, the most important of which in Australia include Didymella pinodes, Phoma pinodella and Phoma koolunga (1). Until now  there have not been any success in developing high level or complete resistance against black spot in the pea germplasm. Breeding for resistance has had only modest success. In addition, recently another challenge has been raised, that of the large temporal and spatial changes of the population of pathogens involved in the black spot complex in Western Australia (2). This is particularly challenging for breeding programs in Australia and elsewhere that have been largely focused on resistance to D. pinodes, ignoring the other pathogens of the black spot complex. Host resistance targeting only one or two pathogens of the complex may shift the make-up of the population toward pathogen species least challenged by the host resistance (2). Therefore, to make resistance more durable, a combination of individual resistances against each of the pathogens in the complex is necessary. The aim of this study was to determine the relative resistance responses on leaf and stem of 40 different field pea genotypes against three important pathogens associated with black spot, viz. D. pinodes, P. pinodella, and P. koolunga.
