乌拉图小麦（Triticumurartu）是多倍体小麦中A染色体组的供体。一个双倍体来源于T. urartu，携带1Ax + Ay高分子量麦谷蛋白亚基;亚瓦罗斯已被合成并用作桥梁物种，将遗传物质从野生小麦转移到栽培小麦。对该双倍体与硬粒小麦回交后获得的20个硬粒小麦品系的品质性状进行了评价。所有品系都选择了1Ax + Ay的存在下，但保持两个不同的模式的低分子量麦谷蛋白亚基和籽粒颜色。红粒品系的色素含量高于黄粒品系。此外，前者的面筋强度高于后者。
Triticum urartu has been identified as donor of A genome in the polyploid wheats. An amphiploid derived from the cross between one accession of T. urartu, carrying 1Ax + Ay high-molecular-weight glutenin subunits, and durum wheat cv. Yavaros has been synthesised and used as a bridge species to transfer genetic material from the wild to the cultivated wheat. Some quality traits were evaluated in twenty durum lines derived from this amphiploid after backcrossing to durum. All lines were selected for the presence of 1Ax + Ay but maintaining two different patterns for the low-molecular-weight glutenin subunits and grain colour. The lines with red grain showed higher pigment content than those with yellow grain. In addition, the former lines present higher gluten strength than the latter ones.
