초록

벼흰잎마름병 방제를 위해 multiline품종을 이용할 경우 가장 이상적인 이병성과 저항성 혼합조합을 찾고자 저항성유전자가 서로 다른 근동질유전자 계통을 이용한 7개 혼합집단의 흰 잎마름병 발병정도, 등숙비율 및 쌀수량에 대하여 그들 혼합집단을 구성하고 있는 요소의 평균과 비교한 결과는 다음과 같다. 1. 7개 혼합집단 즉 ML01, ML02, ML03, MLl2, MLl3, ML23 및 ML0123중에서 ML01과 ML02는 그들 구성 요소의 평균과 발병정도, 등숙비율 및 쌀수량에 있어서 차이를 보이지 않았다. 그러나, 그나머지 혼합집단들은 그들 구성요소의 평균보다 발병정도는 낮았고 등숙비율과 쌀수량은 높았다. 2 Xa3를 가진 HRl1397계통이 혼합된 집단 즉 ML03, MLl3, ML23 및 ML0123이 발병정도도 낮고 쌀수량도 높아 HR11397이 우수한 계통으로 보여진다. 3. 병전파 지연, 병원균집단의 안정화 및 품종의 단인자 저항성 수명 연장을 위한 바람직한 혼합집단 모형은 ML03, MLl3, ML23 및 ML0123이 우수한 것으로 보여진다

Disease severity, percent ripened grains, and yield were investigated in the seven mixtures by using near-isogenic lines having different resistant gene(s) to bacterial blight(BB) of rice. The seven mixtures including the four pure stands were inoculated with a 1:1:1 mixture of races $K_1$, $K_2$, and $K_3$ of BB. Among the seven mixtures-ML01, ML02, ML03, MLl2, MLl3, ML23 and ML0123-, disease severiety, percent ripened grains, and yield of ML01 and ML12, respectively did not show significant difference with those of mean values of their components. But degree of disease severity of the other mixtures, respectively -ML02, ML03, MLl3, ML23, and ML0123-was less than the mean of their components. Percent ripened grains and yield of them were higher than those of mean of their components. ML03, MLl3, ML23 and ML0123 comprised of the equal amount of two or four components having different resistant gene, these mixtures appeared to be a desirable combination for delaying spread of the pathogen, stabilizing of the race structure of the pathogen population, and extending durability of a cultivar with monogenic resistance.
