培育优良品种是提高单产的有效措施。墨西哥通过多年育种工作培育出一系列高产矮秆小麦。这项工作的主持人是诺尔曼·艾伦斯·勃劳格。 15～20年前,墨西哥由于没有适合当地条件的春小麦品种,小麦产量只能满足国内需要的一半。目前,墨西哥已实现粮食自给,每年尚有出口。近年来约有20—30个国家引种墨西哥矮秆小麦,种植面积约6亿 Breeding good varieties is an effective measure to increase yield. Mexico has developed a series of high-yielding dwarf wheat through years of breeding. The host for this work is Noelman Ellensburg. Fifteen to twenty years ago, due to the absence of spring wheat varieties suitable for local conditions in Mexico, wheat production could only meet half of domestic needs. At present, Mexico has achieved self-sufficiency in grain and exports are still exported annually. In recent years, about 20-30 countries introduced Mexican dwarf wheat, planting area of ​​about 600000000
