Summary. Investigation of the plasma protease inhibitor system (Pi) in the Arabian and quarter horse breeds and re‐examination of the standardbred breed resulted in the recognition of two new Pi alleles, designated E and L 2 . Pi E is rare and has been found in only three quarter horses. In contrast, Pi L2 is relatively common in the standardbred (0.107) and allowed subdivision of Pi L into Pi L and Pi L2 . Splitting of Pi L resulted in an exclusion probability (P E ) of 0.649 for the standardbred Pi system. Frequencies of the Pi genes have now been determined for four breeds (thoroughbred, standardbred, quarter horse and Arabian) of horses in Australia.
