1982—1986年从山东省内外有关科研单位及种子部门搜集了当地和国内外表现高产的推广品种、区域试验和杂交高世代品种资源材料共计603份,按年度分批进行了鉴定筛选试验。明确了各份材料的抗性,从中筛选出国育98-4、安东福寿等68份抗性材料。对通过鉴定筛选的表现高产、抗豆荚螟并适于当地夏播的22个品种(系)分期分批的进行了异地联合鉴定试验,进一步明确了其丰产性、抗螟性及适应性。其中鲁豆4号和鲁豆2号两品种表现了既高产又抗豆荚螟,是适于本地种植的夏大豆优良新品种,并已进行了大面积示范推广,为更换本地大豆品种提供了依据。
From 1982 to 1986, 603 domestic and overseas high-yielding varieties, regional trials and high-generation hybrid varieties were collected from relevant scientific research institutes and seed departments in Shandong province and abroad. Clear the resistance of various materials, from which screening of foreign education 98-4, Andong Fushou 68 resistance materials. Twenty-two cultivars (lines) with high yield, resistant to the pod borer and suitable for summer sowing were appraised in different places by batch and batch, and their high yield, resistance to rice borer and their adaptability were further confirmed. Among them, Luding No.4 and Lu Dou No.2 showed high yielding and pod borer, which was a good new summer soybean cultivar suitable for local planting, and had been extensively demonstrated and popularized, which provided a basis for the replacement of local soybean varieties .
