영문 초록

The objective of this study was to investigate the resistance to the rice water weevil (Lissorhoptrus oryzophilus Kuschel) for 35 major rice cultivars in Korea. Resistance was based on the number of larvae and total length of feeding scars in leaves of rice plant. The methods of test was by exposing adults to seedlings of individual cultivar in pots, and seedling of several cultivars in tray at greenhouse. According to the investigation, there was no resistance variety by the individual cultivar method but the varieties of Yeongdeogbyeo, Sangsanbyeo, Sambaegbyeo, Ilpumbyeo, Jinbuolbyeo, Nonganbyeo by several cultivars methods were showed the resistance, and the Nonganbyeo by both methods was only resistant variety. On the other hand, according to the varietal resistance by the total length of feeding scars, Nonganbyeo was resistant by individual cultivar method, and Ilpumbyeo by several cultivars method. A highly positive correlation between the number of larvaes and the total length of feeding scars was observed. For the investigation of resistant varieties to rice water weevil, it was recommended that the combinated tests of individual cultivar method and several cultivars method of exposing adults to rice seedlings, and the moderate resistant cultivars should cultivate at the areas of habitual outbreak of water weevil.
