摘要：在环县干旱山区对引进的8个食用杂交向日葵品种（系）进行了比较试验。结果表明，SR1924折合产量最高，为2 886.7 kg/hm2，较对照品种SH361增产16.71%;W833折合产量2 770.0 kg/hm2，较对照品种SH361增产11.99%;SH363折合产量2 720.0 kg/hm2，较对照品种SH361增产9.97%。这3个食用杂交向日葵品种（系）抗病性强，综合性状表现较好，可在环县种植。

Abstract：In this paper， with a new quinoa cultivar Longli 4 as the control， the performance of six new quinoa strains introduced in Haiyuan dry farming area of Ningxia was analyzed. The results showed that the six introduced quinoa new lines and the control cultivar Longli 4 could mature normally， the growth period was 110～116 days. There were differences in plant height， panicle shape， grain color， 1000-grain weight， stem folding degree and other traits between Longcheno4 and 6 new strains of quinoa. The yield of new quinoa cultivars（lines） were        3 245.78～7 872.89 kg/hm2， among which CA4-1 had the highest yield of 7 872.89 kg/hm2， 9.4% higher than the control cultivar Longli 4，  the yield increase was extremely significant. CA3-1 has the highest 1000-grain weight （3.64 g） and higher yield potential. According to the breeding objectives and production requirements of Haiyuan dryland area， CA3-1 and control cultivar Longli 4 were considered to have excellent comprehensive traits and good breeding， production and application prospects.
