Cultural characteristics, morphology, and pathogenicities of ICMP-2487, a New Zea-land isolate of Alternaria alternata strawberry pathotype were compared with 5 Japanese isolates (OH-5, 90-12, MO-1, SN-3, and MA-2). Concurrently, the resistance of a new strawberry cultivar designated as 'Akita Berry', a somaclonal variant to a New Zealand isolate (ICMP-2487) was examined. The following results were obtained.<BR>1. No differences between the New Zealand and Japanese isolates were found in the growth and colors of colonies, shapes, sizes, and septa of conidia.<BR>2. Pathogenicities of ICMP-2487 to 58 strawberry cultivars and strains, 4 pear culti-vars, 3 cabbage cultivars, 3 tomato cultivars, 3 Welsh onion cultivars, 2 carrot cultivars, and 2 sunflower cultivars were similar to those of Japanese isolates.<BR>3. No lesions on 'Akita Berry' were formed by inoculation of ICMP-2487 and Japanese isolates. This cultivar is, therefore, resistant to the isolates of Alternaria alternata straw-berry pathotype occuring in Japan and in New Zealand.
