Abstract
From 1988-94, 250 surface-sterilized seed samples of Brassica rapa canola from Saskatchewan and Alberta, and 58 samples from one location in Saskatchewan were assessed for seed infection by Alternaria spp. and for seed germination. Alternaria brassicae and A. raphani significantly reduced seed germination while A. alternata had no effect. Infection by these pathogens was an important factor reducing seed germination.
