油菜病毒病,是闽西北内陆山区油菜上的重要病害之一。据调查,一九七五至一九七九年三明地区油菜播种面积约12～13万亩。病毒病每年发生面积约7～8万亩,占油菜播种总面积的58.3～66.6％。一般株发病率15～30％,严重的70％。开展油菜品种对病毒病的抗病性和丰产性的鉴定,为今后发展油菜生产提供科学依据,是油菜病害研究中的重要课题之一。笔者于一九七七年开始此项的研究工作,现已初获成效。归纳整理如下。
Rape virus disease is one of the most important diseases in rapeseed in the inland mountains of northwestern Fujian. According to the survey, the planting area of rapeseed in Sanming from 1975 to 1979 was about 12 to 130,000 mu. Virus disease occurs annually in an area of about 7 to 80,000 mu, accounting for 58.3 ~ 66.6% of the total canola sown area. The general strain incidence of 15 to 30%, a serious 70%. It is one of the important topics in rapeseed disease research to carry out the identification of disease resistance and high yield of rapeseed varieties against virus disease and to provide a scientific basis for the future development of rapeseed production. The author started his research work in 1977 and has achieved initial success. Summarized as follows.
