当今世界上大面积种植的硬粒小麦属于四倍体的一个亚种(Trticum turgidum ssp. Durum).它比普通小麦抗旱,营养价值高(淀粉少,蛋白质、氨基酸、维他命及脂肪酸均较多),但其产量需要进一步提高.目前,法国、意大利和北美的植物育种工作者都在积极从事改良硬粒小麦工作.这种改良工作很多是在国际玉米小麦改良中心的指导下进行的.他们已经培育出一些优良的高代系.这些高代系在适宜的条件下可能超过阿尔及利 Todicum turgidum ssp. Durum, which is grown in large areas in the world today, is more drought resistant and more nutritious than ordinary wheat (less starch, protein, amino acids, vitamins and fatty acids) , But their output needs to be further increased, and plant breeders in France, Italy and North America are actively working on improved durum wheat, much of this improvement is being done under the guidance of the International Corn and Wheat Improvement Center Some excellent high-generation families have been breed, which may surpass Algiers under appropriate conditions
