Descriptions
Puccinia coronata Corda 1837
Cunningham, (1931a) stated that aecidiosori have not been collected in New Zealand and that the rust is perpetuated by means of uredospores overwintering on grass hosts. He concluded that the rust species consists of numerous forms separable by their reactions towards differential hosts. Cruickshank (1956) found that there were 13 physiological races of Puccinia coronata f. sp. avenae present in New Zealand; he investigated resistance of hybrid ryegrass strains to P. coronata f. sp. lolii and found that short-rotation ryegrass is highly resistant to crown rust, whilst perennial ryegrass is highly susceptible (Cruickshank, 1957b). Puccinia coronata can be troublesome in oat crops in Canterbury (Wratt, 1956). It is very common in ryegrass throughout New Zealand, sometimes making it unpalatable to stock (Cruickshank, 1957b; Latch, 1966a).
