초록
본 연구는 연계재배 검정을 통해 도열병에 대한 내구저항성품종으로 판단된 29개 벼 품종들의 11년간 14개소에서 밭못자리검정 결과를 이용하여 도열병에 대한 내구저항성 특성을 비교분석한 결과이다. 29개 품종들의 밭못자리 검정에서 평균 발병정도 3.4로 중도저항성을 보였고, 평균 발병정도의 범위는 최소2.0에서 최대 6.1로 나타났다. 시험품종 가운데 12품종은 평균발병정도가 3.0이하의 저항성을, 나머지 17개 품종들은 중도저항성 반응을 나타내었다. 저항성 반응을 보인 12개 품종 가운데, 운광벼, 풍미1호, 신운봉1호, 다산1호 등 4 품종은 전 시험기간에모든 시험지에서 발병정도 차이가 적었다. 고품벼를 포함한 21개품종들은 시험 지역간 발병차이가 시험 연차간 차이보다 컸고, 동진2호 등 8개 품종은 시험 연차간 발병정도 차이가 컸다. 내구저항성 품종들은 밭못자리 검정에서도 전 시험기간 동안모든 시험지역에서 중도저항성 이상의 저항성 반응을 보여 이들저항성이 오랜 기간 지속될 것으로 판단되었다.
Abstract
Blast resistance of 29 rice cultivars confirmed as a durable resistance in the evaluation of sequential planting from 2004 to 2006 was evaluated to nursery screening in 14 test sites during 11 years in Korea. The average disease severity (ADS) of 29 rice varieties against rice blast showed 3.5 degree; however, the difference of disease severity among the varieties was from 1.9 to 4.8. The 29 varieties were grouped into resistance less than 3.0 ADS degree including 12 varieties and moderate resistance over 3.1 ADS degree including 17 varieties. Among the 12 rice cultivars presented low ADS, 4 rice cultivars, Ungwang, Pungmi 1, Sinunbong 1, and Dasan 1 were constantly appeared high resistant reaction during 11 years in all test sites and the others were showed various diseases severity across the test years and the test sites. Twenty-one rice cultivars including Gopum were more variable among the test sites while the others were higher variable among the test years. These results indicated that durable resistance test against rice blast using sequential planting is a very efficient screening method to predict durability and nursery test for long periods and also useful method to predict indirectly durable resistance of rice cultivars.
