花生种质抗旱性鉴定技术初步研究

Studies on Identification Technology of Drought Resistance of Peanut Germplasm

在17.5%PEG6_(000)水分胁迫处理下,在实验室鉴定了10个花生品种的萌芽期抗旱性;在田间干旱条件下,通过灌溉水分控制对东北地区主栽花生品种进行生育后期抗旱性鉴定。结果表明,不同花生品种抗旱性存在显著差异,两种方法结合可以更准确地鉴定花生种质(品种)的抗旱性。

Under 17.5% PEG6000 water stress treatment, drought resistance of 10 peanut varieties in seedling emer-gence stage was identified. In the field under natural drought condition with controlled irrigation, the main peanutvarieties in the northeast of China were evaluated. The results showed that significant differences existed in droughtresistance of different varieties. Combined with the two methods, evaluation of the peanut germplasm（varieties）could be more accurate.
