| Abstract |
|
The rice diseases occurring on the transgenic rice plant carrying protox gene (CPPO06) was assessed and compared with other varieties of rice such as Dongjin, Chucheong, Ilpeum, and Onnuri in the fields located in Cheongwon of Chungbuk, Suwon of Gyeunggi, and Gwangju of Chonnam. In the field of Cheongwon, the diseases such as blast, leaf spot, sheath blight and Fusarium blight were observed. False smut were observed only in the field of Suwon, where the ratio of diseased plants was 0.28% in CPPO06 and 0.37% in Onnuri, respectively. In the field of Gwangju, leaf spot caused by Cochlioborus miyabeanus was the most severely occurring disease among rice diseases mentioned above. Fusarium blight occurred in all the 3 fields, which were more severe in CPPO06 plants treated with or without oxadiazon as the herbicide. Except for Fusarium blight, there was no significant difference in the rice diseases as blast, leaf spot, sheath blight and false smut between CPPO06 and other rice varieties. |
