摘　　要：试验对华亚2号、华亚3号、华亚4号、华亚5号、Amine(荷兰)和Vesta(荷兰)6个亚麻品种在2018—2021年内5个关键农艺性状和4个产量性状的变化趋势以及相关性进行分析。结果表明,6个亚麻品种蒴果数和种子产量的变异系数较大,稳定性相对较弱,其余农艺性状均表现出较好的变异性。其中华亚2号、华亚5号、Amine和Vesta干茎制成率的变异系数均小于3%,变异幅度小,稳定性较强。6个亚麻品种的种子产量、纤维产量、原茎产量和全麻率的变化趋势不同:华亚2号、Amine和Vesta亚麻品种种子产量均呈上升趋势;华亚2号、华亚4号、华亚5号和Amine的原茎产量呈上升趋势,其余两种呈略下降趋势;华亚3号纤维产量略下降,其余品种整体呈上升趋势;6个亚麻品种的全麻率变化趋势稳定。相关性分析结果显示,株高、工艺长是影响亚麻原茎产量和纤维产量的最主要因素,与原茎产量和纤维产量均呈极显著正相关(p<0.01),株高和工艺长是影响亚麻产量的重要性状,提高亚麻品种的株高和工艺长是提高纤维产量和原茎产量的有效途径。上述研究为亚麻育种规划、开发高产改良品种提供理论基础。The growth trends and correlations among five key agronomiccharacters and four yield charactersofsix flax varieties, Huaya 2, Huaya 3, Huaya 4, Huaya 5, Amine(Netherlands) and Vesta(Netherlands), were analyzed from 2018 to 2021.The results showed that the variation coefficients of capsule number and seed yield of the six flax varieties were large, and their stabilities were relatively weak. Other agronomic traits showed good variability. The coefficient of variation of stem yield of Huaya 2, Huaya 5, Amine and Vesta were all less than 3%, with small variation range and strong stability. The change trends of seed yield, fiber yield, stem yield and total flax percentage of the six flax varieties were different. The seed yield of Huaya 2, Amine and Vesta flax varieties all showed an upward trend. The stem yield of Huaya 2, Huaya 4, Huaya 5 and Amine all showed an upward trend, while the other two showed a slightly downward trend. The fiber yield of Huaya 3 decreased slightly, while that of other varieties showed an overall upward trend, and the general flax percentage of the six flax varieties showed a stable trend of change. The results of correlation analysis showed that plant height and technological length were the most important factors of flax stem yield and fiber yield, and they were positively correlated with both of them(p<0.01), plant height and technological length were important characters that affected flax yield. Increasing plant height and technological length of flax varieties was an effective way to increase fiber yield and stem yield. The study above provides a theoretical basis for flax breeding planning and development of high-yield improved varieties.
