摘　　要：１９９０－１９９１年连续两年选用来自国内外不同生态型有代表性的１００份大麦种质资源，在大田进行秋、春两季播种和长日照（１６－１８ｈｒ）和春化（０－３℃，２０ｄ）处理，系统地观察分析有关指标，将其中１３个生育期指标应用系统聚类的最短距离法进行聚类结果：１００份大麦种质资源按光温反应的差异主要分为三个类型，即春型、半冬型和冬型，并对各类型大麦光温反应特性进行讨论，建立不同类型光温发育模型。This study was carried out during 1990-1991. 100representative barley germplasm resources of varietal ecotypes were sowed in field respectively in spring and autumn. Longday lenth (16-18h) and vernalization (0-3℃, 20d) treatment was made through. 13development stages were adopted as clustering critevions, the results showed that these sample are divided into 6 groups. By the three principal types, We mean springness, middle and winterness. Their characteristics are also dealt with, and their development models of photo-temperature are established.
