玉米是我省主要粮食作物，遭受三病一虫危害严重，采取有效的综合防治措施是种植抗病丰产杂交种，为此“八五”国家攻关列题。我们承担筛选兼抗和多抗性新杂交组合和抗源自交系任务，采用院内田间人工接种（三病一虫）和院外不同生态区田间自然诱发条件下进行抗病性鉴定，筛选多抗玉米材料２１７份，为育种和推广提供科学依据。
Maize is the main food crop in our province and is seriously endangered by the disease and worm. Effective comprehensive prevention and control measures are to plant high-yield hybrids with high disease resistance. We undertake screening and anti-and multi-resistant new hybrid combinations and resistance to inbred lines task, the field artificial inoculation (three disease and one worm) and field outside the hospital naturally induced disease resistance identification, screening polyclonal 217 copies of corn material, provide scientific basis for breeding and promotion.
