摘　　要：为了初步探明优质强筋春小麦津强5在东北春麦区的品种适应性,本研究通过分析2009—2011连续3年天津武清地区津强5整个物候期的气象特征,总结津强5的生育特点,预测东北春麦区满洲里、通辽、赤峰和锦州4地津强5的引种可能性。利用欧几里德距离公式,计算上述4地与天津武清点在津强5适种期期间的气候距离系数,明确4地的引种相对可能性。结果发现,津强5出苗需要178.1℃以上的活动积温,温度积累593.1℃完成抽穗,温度积累913.2℃、光照积累282.9 h才能够正常成熟;津强5能够在满洲里、通辽、赤峰和锦州4个地区完成整个生长周期,距离系数分析表明锦州地区引种的相对可能性最高,通辽和赤峰次之,满洲里的相对可能性最低。In order to reveal the adaptability of high-quality strong gluten spring wheat variety ＂Jinqiang 5＂ in the northeastern spring wheat region, the growth characteristics of ＂Jinqiang 5＂ were studied in Wuqing Tianjin in 2009-2011 growing season to predict the introduction possibility of this variety in 4 locations of the northeast spring wheat region, Tongliao, Chifeng , Jinzhou and Manzhouli. Meanwhile, the climate similarity between Wuqing Tianjin and these 4 locations in growing season of ＂Jinqiang 5＂ were calculated to definite relative possibility with formula of Euclid＇s distance. The results showed that 4 locations all could satisfy with the condition, 〉10 ℃ active accumulated temperature needed for normal emergence ,heading and maturation of ＂Jinqiang 5＂ were 178.1 ℃, 593.1 ℃ and 913.2 ℃ respectively and illumination time needed for filling were 282.9,and could complete the whole growing period of ＂Jinqiang 5＂; Analysis of distance coefficient showed that the relative possibility of introduction in Jinzhou was the highest, in Tongliao and Chifeng second , in Manzhouli lowest.
