烟草黑胫病在我省发生普遍而严重,是我省烟草生产中的重要病害之一。抗病品种是防治该病的有效措施,但自七十年代以来,这一工作有所放松,致使病情回升,且日趋严重,严重影响我省烟草生产的发展。为此,我们于1984—1986年,对我省各地已经推广种植或新引进、新育成的烟草品种和我所新育出的高代株系及一些原始材料,进行了病圃抗病性鉴定工作,以便找出优良抗病的烟草品种(系),为防治和育种工作提供科学依据。一、材料来源参加试验的材料共89个,均由本所育种室提供,包括引自国内外的品种34个,本所育种室及本省其他育种单位育成的品种(系)
Tobacco black shank disease in our province is widespread and serious, is one of the important diseases in tobacco production in our province. Disease-resistant varieties are effective measures to prevent and treat the disease. However, this work has been relaxed since the 1970s, causing the disease to pick up and become increasingly serious, seriously affecting the development of tobacco production in our province. To this end, in 1984-1986, we carried out the identification of disease resistance of nursery gardens on the tobacco varieties that have been planted or newly introduced, newly bred and the new generation of high-yielding lines and some raw materials that have been newly raised in our province. Work in order to find good varieties of tobacco resistance (lines), to provide a scientific basis for prevention and breeding work. I. MATERIAL SOURCES 89 materials participated in the experiment, all of which were provided by our breeding room, including 34 varieties introduced from home and abroad, varieties cultivated by our breeding room and other breeding units in our province,
