1985年在南京对来自江淮下游地区105份大豆材料的抗旱性进行了初步研究。在此基础上,选取有代表性的67份大豆品种于1986年进一步进行品种生育前、后期的抗旱性鉴定。结果表明:抗旱品种和干旱敏感品种较少,中间型占大多数。其中徐州小油豆、崇明铁梗豆和丰县孙楼子黄豆在生育前后期均表现较强抗旱性。所供试的6个栽培品种在生育前后期抗旱性中等偏下。品种生育前期抗旱性与生育后期抗旱性无相关性。 In 1985, the drought resistance of 105 soybean materials from the lower reaches of the Yangtze-Huaihe River was studied in Nanjing. On this basis, we selected 67 representative soybean varieties for further identification of drought resistance before and after breeding in 1986. The results showed that drought-tolerant cultivars and drought-sensitive cultivars were less and the middle type accounted for the majority. Among them, Xuzhou Small Oil Bean, Chongming Iron Terrier Bean and Fengxian Sun Louzi Soybean showed strong drought resistance both before and after the birth. The six cultivars tested were moderately drought resistant before and after fertility. There was no correlation between the drought resistance at early growth stage and the drought resistance at later growth stage.
