Abstract
Specific immune serum against Ascochyta pisi was developed and three species-specific reactions were obtained by standard absorption techniques using extracts of both Ascochyta pinodella and Ascochyta pinodes. Ouchterlony tests showed a complex pattern of precipitation reactions in agar gel between the antigens from the three species and antisera developed in response to them and indicated distinct serological relationships among the three fungi. The pattern of reciprocal precipitin reactions indicates a closer serological relationship between A. pinodella and A. pinodes than between either of these two species and A. pisi. Two serologically similar antigenic components were present in the extracts from the three species.
