我国引进国外小麦品种11,000余份,保存具有生活力的约7,000份。由于各国家的自然条件和农业条件差别很大,加之育种方向不尽相同,因而各地小麦品种的特征特性,也具有明显的不同。对其进行分析研究,将有助于我们对不同国家小麦品种的深入认识,从而总结引种规律,寻找遗传源中心,为进一步引种提供科学依据。同时也有助于在我国小麦育种和生产中,更好地选用国外品种。现以在北京观察鉴定的结果为主,结合各地的试验资料,将主要国家的小麦品种在我国表现的主要特点及适应地区分述如下。
In China, more than 11,000 foreign wheat varieties have been introduced, preserving about 7,000 viable vitamins. Due to the great differences between the natural conditions and agricultural conditions in various countries and the different breeding directions, the distinctive characteristics of wheat varieties in different places also have obvious differences. The analysis will help us understand the wheat varieties in different countries in depth, so as to summarize the rules of introduction, find the center of genetic resources and provide a scientific basis for further introduction. At the same time, it also helps to better select foreign varieties in wheat breeding and production in China. Now the results of the observation and appraisal in Beijing are mainly based on the test data from all over the world. The main characteristics of the wheat varieties in major countries and their adaptation regions are described as follows.
