中文摘要	本研究以13个藜麦引选品种为材料,测定记录其出苗率、物候期、植物学特征、产量、品质及抗性等指标,并应用聚类分析法对其主要性状的相关性进行评价,探究供试品种在甘肃临夏旱作区的适应性表现。结果表明,13个藜麦供试品种在试验区域均可以成熟,并且这些品种在株高、分枝数、有效分枝率、主枝穗长度、主枝穗直径、千粒重、产量、粗蛋白、粗纤维含量等指标上差异显著;通过聚类分析发现品种Q_7、Q_8属于矮化早熟品种,品种Q_9经济性状最好,产量达4246.6 kg/hm~2,较对照增产1252.1 kg/hm~2,品种Q_1、Q_7、Q_8、Q_9、Q_(10)均属于抗病品种;不同藜麦品种表型性状与产量性状、品质性状无显著相关性,但产量和品质呈负相关。综合产量性状、品质性状和抗性评价,品种Q_9的经济性状最优,具有在甘肃临夏旱作区大面积推广种植的潜力。
英文摘要	In order to study adaptive performance of quinoa varieties in the Linxia arid region of Gansu province, we tested 13 different quinoa varieties (designated CK, Q_1 to Q_(12)), to determine seedling emergence rate, phenology, botanical characters, yield, quality and disease resistance. Cluster analysis was applied to evaluate the relationships among selected traits. It was found that all 13 quinoa varieties are able to reach maturity in the test region. There were significant differences among varieties for plant height, branching index, effective branching rate, inflorescence spike length, inflorescence spike diameter, thousand kernel weight, and crude protein and crude fiber content. In addition, cluster analysis revealed Q_7 and Q_8 are dwarf early varieties, while varieties Q_1, Q_7, Q_8, Q_9, Q_(10) show disease resistance. Q_9 is high yielding (4247 kg/ha, 1252 kg/ha higher than control). There were no phenology characters of obvious relevance to variety choice. Considering all factors measured, Q_9 had the best all round performance and could potentially be planted more widely as a crop in the Linxia arid region of Gansu province.
