The results of a four‐year investigation carried out in Central Italy on the occurrence of perennial ryegrass rusts from 1989—92 are reported. The crown rust (Puccinia coronata) was the most frequently recorded in the surveyed are while P. graminis was only occasionally detected. The causal agents were identified by the morphological criteria proposed by CUMMINS (1971). A single‐pustule isolate of P. coronata was used to test the resistance of seven ryegrass cultivars under greenhouse conditions. Two cultivars, ‘Artal’ and ‘Score’, proved resistant to the fungus isolate while the remaining (‘Elka’, ‘Patora’, ‘Pleno’, ‘Sisu’ and ‘Vejo’) were high susceptible.
