한국에서 1920년경부터 1956년까지 재배되었던 조동지, 용천을 비롯한 74재내품종을 5개균군을 사용하여 저항성정도를 조사한 결과 1. 조동지, 용천, 애달, 용산, 대구, 밑다리, 풍옥을 포함한 69품종은 본병에 이병성인 금남풍군에 속하였다. 2. 흑수, 도입남, 황판은 황옥군이였다, 3. 남각, 강북도의 반응은 지금까지 알려지지 않았던 반응을 나타냈다. 4. 금남풍군에 속하는 69품종의 균군별 반응은 I균군이 , II균군, III균군, IV균군 V균군로 놓은 발병주율을 보였다. 5. 황옥군에 속하는 3품종은 I균군 II균군 , III 균군 , IV균군 , V균군 로 판별품종의 반응과 비슷하였다
The resistance to bacterial leaf blight of Conventional varieties (chodongi, Yongcheon etc.) cultivated from 1920 to 1956 in Korea were tested by means of 5 pathotypes of causal organism Xanthomonas oryzase (Uyeda et lshiyama) DOWSON. The results of this test are: 1. Among 74 varieties, 69 varieties including 'Chodongji, Yongcheon, Aedhal, Yongsang, Daegu, Mitdhari, pungok, etc' belong to the Kinmaze group that is highly susceptible to this disease. 2. 3 varieties: Heukbal, Doipnam, Whangphan belong to the Kogyoku group. 3. 2 varieties: Namgok, Gangbukdo, show unknown reaciton to differential varieties. 4. In 69 varieties belonging to the Kinmaze group of the plants were infected by bacterial group I. in bacterial group II. in group III, in group IV, and in group V. 5. In 3 varieties belong to Kyogyoku group, of the plants were infected in bacterial group I. in group II, in group III, IV and in group V.
