Abstrakt: The kiwifruit brand Sanuki Kiwicco® comprises five kiwifruit cultivars (KagawaUP-Ki1, −2, −3, −4, and − 5) that are hybrids of Actinidia chinensis and Actinidia rufa, have high quality, small fruits with a sugar content of 17 to 20% and a low level of protease, thus eliminating any mouth irritation. The cultivars of Sanuki Kiwicco® are more tolerant to bacterial blossom blight and can be stored longer than previously released cultivar Kosui, another hybrid between A. chinensis and A. rufa. Our investigations using A. rufa, a wild species in warm regions of Japan, revealed efficient transduction of tolerance to bacterial canker disease caused by Pseudomonas syringae pv. actinidiae biovar 3. The Sanuki Kiwicco® cultivars also proved to have practical tolerance to the disease caused by biovar 3 in laboratory and field tests. [ABSTRACT FROM AUTHOR]
