摘　　要：为筛选出适宜高寒干旱区种植的藜麦新品种(系),客观、科学、准确地评价藜麦新品种(系)的适应性及其表现,加速藜麦新品种(系)的应用与推广,对引进的8个藜麦新品种(系)在宕昌县进行了引种比较试验,并对各品种(系)的生育期、成熟期农艺性状及产量进行数据分析和综合评价。结果表明,各参试藜麦新品种(系)在试验区域内均能正常成熟,适宜在宕昌县海拔2000~2600 m的地区种植。平均折合产量以1564-1最高,为4503.96 kg/hm^(2);陇藜4号、4F-21平均折合产量较高,分别为4424.68、4398.97 kg/hm^(2)。在宕昌县及地理气候相似的高寒干旱区大面积发展藜麦生产时,建议将1564-1作为主栽品种,4F-21作为搭配品种。This study was aimed to screen new quinoa varieties(lines)suitable for planting in alpine arid areas and to evaluate the adaptability and performance of new quinoa varieties(lines)objectively,scientifically,and accurately,so as to accelerate the application and promotion of new quinoa varieties(lines).8 introduced quinoa varieties(lines)were used for comparative tests in Tanchang County.Data analysis and comprehensive evaluation were conducted based on the growth periods,agronomic traits at maturity,and yields.The results showed that 8 introduced quinoa varieties(lines)could mature in the experimental area,and were suitable for planting in areas with an altitude of 2000 to 2600 meters in Tanchang County.The 1564-1 had the highest average yield equivalent which was 4503.96 kg/ha,followed by Longli 4 and 4F-21,which were 4424.68 and 4398.97 kg/ha,respectively.In Tanchang County and similar ecological regions,it is recommended to cultivate 1564-1 as main varieties and 4F-21 as a complementary variety for large-scale quinoa production.
