Fiber Content in Stem and Fiber Yield in the Chosen Genetic Resources of Flax (Linum Usitatissimum L.)

ABSTRACT

The flax and hemp genetic resources collection gathered by the IWNiRZ – PIB the Institute of Natural Fibres & Medicinal Plants – National Research Institute (iNNi R2) is very important for protection of biodiversity (http://www.biodiv.org). Presently, the flax collection of IWNiRZ Gene Bank comprises 829 accessions, including wild forms and landraces, primitive and advanced cultivars as well as varieties and breeding lines. Hemp collection holds about 150 accessions from various regions of the world. Genetic resources of flax and hemp are very important for health. The IWNiRZ is involved in the valorization of morphological biological features and economic traits of genetic resources of flax, hemp and herbal plants. This article characterizes two economic traits of 264 accessions of flax from many countries of the world: fiber content in stem and fiber yield. The IWNiRZ is involved also in developing The International Flax Data base, therefore the results are also presented in the form of a descriptive assessment, using special descriptors. The range of variability of the fiber content of 263 tested flax accessions ranges from 9.9% – Argentina 346 (INF00201) to 28.9% – Dacota C.I. 1072 (INF00026). The results of fiber content of 263 flax accessions according to the International Flax DataBase methodology are as follows: very low content of fiber – 27 accessions of flax (10.3% of evaluated accessions), low – 151 accessions of flax (57.4%), medium – 55 accessions of flax (20.9%), high – 28 accessions of flax (10.6%) and very high – 2 varieties (0.8%). The fiber yield results could not be prepared for the International Flax Database because the plot of the experiment was too small to be considered reliable. The IWNiRZ collection contributes as a valuable source for breeders when selecting useful parental components and also secures breeders’ achievements.

摘要

IWNiRZ–PIB–天然纤维与药用植物研究所–国家研究所 (INF&MP-NRI) 收集的亚麻和大麻遗传资源对于保护生物多样性非常重要(http://www.biodiv.org). 目前, IWNiRZ基因库收集的亚麻包括829份材料, 包括野生型和地方品种, 原始和高级品种以及品种和育种系 . 大麻收藏收藏了来自世界不同地区的约150份材料 (Mańkowska和Silska, 2015年) . 亚麻和大麻的遗传资源对健康非常重要 . IWNiRZ参与亚麻 , 大麻 和草本植物 遗传资源的形态试验, 生物学特征和经济特征的评估. 本文描述了世界各国264份亚麻材料的两个经济性状:茎中纤维含量和纤维产量. IWNiRZ还参与开发国际亚麻数据库, 因此, 结果也以描述性评估的形式呈现, 使用特殊的描述符. 263份供试亚麻材料的纤维含量变异范围为9.9%-阿根廷346 (INF00201) 至28.9%-达科塔C.I.1072 (INF00026) . 根据国际亚麻数据库方法, 263份亚麻材料的纤维含量结果如下:纤维含量极低-27份亚麻材料 (占评估材料的10.3%), 低-151份亚麻材料 (57.4%), 中-55份亚麻材料 (20.9%), 高-28份亚麻材料 (10.6%) 和非常高的2个品种 (0.8%) . 国际亚麻数据库无法编制纤维产量结果, 因为实验的图太小, 无法认为是可靠的. IWNiRZ系列为育种家在选择有用的亲本成分时提供了宝贵的资源, 同时也确保了育种家的成就
