Abstract
The incidence rates of postharvest fruit rots of four kiwifruit cultivars which were cultivated under rain-proof tunnel house at a same orchard were examined. Among them, 'Halla-Gold', 'Jecy-Gold' and 'Jecy-Sweet' were new cultivars bred in Korea. The disease incidence was varied with cultivars; 74.8%, 65.3%, 57.1% and 16.2% for 'Hayward', 'Halla-Gold', 'Jecy-Sweet' and 'Jecy-Gold' cultivars, respectively. Two hundred and eighteen isolates were obtained from diseased fruits and identified by mycological and molecular biological methods. Three fungi, Botryspheria dothidea, Diaphorthe actinidiae and Botrytis cinerea, were identified as pathogens of the postharvest fruit rots with detection rates of 95.4%, 4.6% and 2.3%, respectively.
