Characteristics of the New Fiber Flax Variety HERA in Terms of Fiber Quality Parameters Regard to Agronomic Assessment and Seeds Quality

The work deals characteristics of new flax Hera variety in terms of fiber quality with regard to agronomic assessment and seeds quality. The results of the analyzes were related to the reference varieties Nike, Sara and Modran grown in Poland in 2022 season. The study included evaluation of agrotechnical experiment, flax straw and fiber evaluation taking into account the morphology and surface as well cross section of flax fiber. Moreover, seeds quality assessment were conducted. Hera variety was characterized by the highest total (6.27 t/ha, 0.627 kg/m2) and straw yield (5.16 t/ha, 0.516 kg/m2). Straw of Hera variety was characterized by the best average total (78.5 cm) as well as average technical (66.5 cm) length and average diameter (1.43 mm). In addition, it has fiber to raw straw content (16.42%) at a level comparable to the reference varieties. The metrological analysis of the fiber showed that the Hera variety fiber can be a good raw material for production of yarns.

本研究针对新型亚麻品种Hera的纤维品质特性展开研究，并同步开展农艺评价与种子品质分析。本次分析将试验结果与2022年在波兰种植的对照品种Nike、Sara及Modran进行了关联对比。研究内容涵盖农艺试验评价、亚麻秆与纤维的品质检测，其中纤维检测包含形貌、表面结构及横截面分析；此外还开展了种子品质评价工作。Hera品种的总产量（6.27吨/公顷，0.627千克/平方米）与亚麻秆产量（5.16吨/公顷，0.516千克/平方米）均为最高。Hera品种的亚麻秆平均总长度（78.5厘米）、平均工艺长度（66.5厘米）及平均直径（1.43毫米）均表现最优。此外，其纤维占原秆的比例为16.42%，与对照品种处于同一水平。纤维的计量分析表明，Hera品种的亚麻纤维可作为生产纱线的优质原料。
