Abstract
Screenhouse experiments were conducted to find out the varietal difference in ovipositional preference of the striped rice borer moths (Chilo suppressalis W.) on eight varieties of rice and its association with several plant morphological characters. The results indicated the strong preference of the moths for ovipositing on several varieties. The varieties Tongil (Suweon 213-1), Yushin, Jinheung and TKM-6 had comparatively more egg masses and more eggs than the varieties IR-26, IR-747, Rexoro and Juckna. The strong ovipositional preference of moths of Tongil, as compared to the resistant variety TKM-6 and the susceptible variety Rexoro, was. always consistent in this study whenever the number of tillers were uniformed and each two varieties were paired. It could be concluded that the moths definitely preferred Tongil among the test varieties. There was not any significant correlations between the ovipositional preference and the plant characters; such as number of tillers per plant, plant height, external diameter of stem, and size of leaf. The cause of strong perference of the moths for ovipositing on short type varieties Tongil and Yushin were still suspectable.
몇 가지 수도품종에 대한 산란선호성의 차이, 또는 산란선호성과 품종의 몇 가지 외형적 특성과의 관계를 알아보기 위해 본 실험을 실시하였다. (1) 품종에 따라 산란선호성에 현저한 차리가 있었는데 그중 산란선호성이 비교적 큰 품종은Tongil (Suweon 213-1), Yushin, Jinheung 및 TKM-6이었고 비교적 낮은 품종은 IR-26, IR-747, Rexoro 및 Juckna이었다. (2) Tongil, TKM-6 및 Rexoro 세 품종 중 산란선호성이 가장 높은 품종은 Tongil이었고 다음이 TKM-6, 가장 낮은 품종이 Rexoro품종이었는데 그 경향은 주당경수가 일정할 때나 차이가 있을 때나 일치하였다. (3) 산란선호성과 공시품종의 주당경수, 초장, 엽의 폭과 길이 및 경의 굵기와는 유의한 상관관계가 없었다. (4) 산란선호성의 기작은 품종의 외형적 특성을 검토하기 보다는 오히려 품종의 해부학적 또는 생리화학적인 면에서의 검토가 필요할 것으로 생각되었다.
