大豆孢囊线虫病(Heterodera glycines,Ichinohe)已在山东省普遍发生,成为大豆生产上最严重的病害。大量研究表明,利用植物本身的抗病性来控制该病的危害是最经济有效的措施。我室于1986年开始了大豆孢囊线虫病的抗性遗传育种研究,已取得初步结果,简报如下: (一)大豆孢囊线虫病的调查和病原生理小种鉴定: 从1986年起,我们选择全省有代表性的县、区进行调查,发现在所有抽查地块上
Heterodera glycines (Ichinohe) has been a common occurrence in Shandong Province and has become the most serious disease in soybean production. Numerous studies show that the use of plant disease resistance to control the harm of the disease is the most cost-effective measures. Our laboratory started the research on the resistance genetic breeding of soybean cyst nematode disease in 1986, and preliminary results have been obtained. The briefing is as follows: (I) Investigation and identification of pathogen of soybean cyst nematode: Since 1986, we Select the province’s representative counties and districts to investigate and found that in all the sampling plots
