以藜麦新品种陇藜4号为对照,对6个引进的藜麦新品系在宁夏海原旱作区的表现进行了分析。结果表明,引进的6个藜麦新品系和对照陇藜4号均能正常成熟,生育期为110~116 d。株高、穗形、籽粒颜色、千粒重、茎秆易折度等性状在陇藜4号和6个引进的藜麦新品系间存在不同程度的差异。参试的藜麦新品种(系)的折合产量为3 245.78~7 872.89 kg/hm2,其中以CA4-1折合产量最高,为7 872.89 kg/hm2,较对照品种陇藜4号增产9.4%,增产极显著。CA3-1茎秆不易折断,千粒重最高(3.64 g),增产潜力较大。根据海原旱作区的育种目标和生产需求,认为CA3-1和对照品种陇藜4号的综合性状较为优异,具有较好的育种和生产应用前景。

[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.
