한국(韓國) 수도품종(水稻品種)의 도열병(稻熱病) 저항성(低抗性)에 관(關)하여 I. 일본형품종(日本型品種)

This experiment was undertaken to clarify derivation of resistance of Japonica type of rice varieties to rice blast in Korea and to classify Japonica type of rice varieties on the basis of their rice blast reaction in the blast nuisery test. 1. The resistance of Iljin, Kwancheok 9, Koshi, Baedal and Paldal, Jaekeon, Sinpung, Jinheung, Hokwang and Palkeum, and Gwangmyungbyeo and Yeongdeogbyeo to rice blast was derived from Kyudai Taicho Asahi 3, Futaba and 2067, respectively. 2. The resistance of Kwanok, Mankyeong and Nongbaek to the rice blast was derived from Kanto 55, Hokwang and Kusabue, and Ishigarisiroge, respectively. 3. The resistance of Seomjinbyeo, Sinseonchalbyeo, Donghaebyeo and Tamjinbyeo to the rice blast was derived from Milyang 20 and the source of resistance to the rice blast in Jinjubyeo and Daecheongbyeo was HR 769 or HR 1590. 4. The resistance of Dobongbyeo, Gwanagbyeo and Chiagbyeo to the rice blast was derived from Tjina, Kongo and Kuik 90, respectively. 5. The resistance of Seolagbyeo, Seonambyeo, Kihobyeo, Namyangbyeo, Samnambyeo, Seohaebyeo, Whaseongbyeo, Daegwanbyeo and Taeseongbyeo, and Sobaegbyeo, Odaebyeo and Unbongbyeo to the rice blast was derived from Fuji 280 and Fuji 269, respectively. 6. The source of resistance to the rice blast in Cheonmabyeo and Baegambyeo was BL 7 and Nongbaek, the resistance of Dongjinbyeo and Sangpungbyeo to the rice blast was derived from Satominori and Simokita, respectively. 7. Japonica type of rice varieties was classified into eleven varietal groups according to their reaction to the blast as follows. Eight varieties of Jinheung group, two varieties of Dongjinbyeo group, two varieties of Jinjubyeo group, three varieties of Gwanagbyeo group, four varieties of Sobaegbyeo group, one variety of Nongbaek group, two varieties of Baegambyeo group, five varieties of Sinseonchalbyeo group, five varieties of Seonambyeo group, two varieties of Taeseongbyeo group and some variety of Nagdongbyeo group.
