美国密苏里大学农学部的小麦育种专家阿斯特尔博士,培育了一种蛋白质含量特高的超级营养小麦。普通小麦的蛋白质含量只有13%,加拿大培育的一种小麦蛋白质含量达15%,而超级营养小麦的蛋白质含量达到26.5%,高出普通小麦一倍以上。超级营养小麦是用野生小麦原种和野生牧草杂交后培育而成的。这种小麦的颗粒大,产量比普通小麦高8—10%。但它有一个明显的缺点,就是麦秆脆而易倒伏,因而给机械化收割带来困难。但 Aster, a wheat breeding expert from the Department of Agronomy at the University of Missouri in the United States, developed a super-nutritious wheat with a high protein content. The average wheat protein content of only 13%, Canada, a wheat protein content of up to 15%, while the super-nutrient wheat protein content of 26.5%, higher than the common wheat more than doubled. Super-nutritive wheat is cultivated after the wild wheat is crossed with wild grass. This kind of wheat is large in grain size and produces 8-10% more yield than common wheat. However, one obvious disadvantage is that the stalks are brittle and prone to lodging, thus creating difficulties for mechanized harvesting. but
