Valorization and Analysis of Flax Traits in Selected Accessions of Diversified Origin from the Linum usitatissimum L. Genetic Resources Collection

ABSTRACT

Genetic resources of flax from different geographical regions have been gathered in Poland since the 1930s. The aim of the research was to evaluate morphological and agricultural traits of 20 flax accessions, to determine the ranges of variability, and to develop the results in the form required for International Flax Database (IFDB) development. Obtained data were statistically analyzed using ANOVA with post hoc tests (least significant differences), canonical correlations, and Mahalanobis distances. The results of the analysis (ANOVA) proved that five traits of flax varieties differ significantly: plant height, technical length, slenderness, 1000 seeds weight, and seed yield. The ranges of variability of flax genotypes: total plant length: 58.05 cm−92.8 cm; technical length: 44.7–78.6 cm; stem thickness: 1.42–2.18 mm; slenderness: 246–474; panicle length: 10.05–21.55 cm; number of panicle branches: 3.4–6.2; number of capsules per plant: 5.15–19.7; number of seeds in capsule: 6.24–7.86; 1000 seeds weight: 4.82 g − 7.72 g. The results of the investigation could provide an important step of initial material selection for breeding of new varieties as well as information for entrepreneurs and private consumers and by students and scientists for their research.

摘要

自20世纪30年代以来，波兰收集了来自不同地理区域的亚麻遗传资源. 研究的目的是评估20份亚麻种质的形态和农业性状，确定变异范围，并以国际亚麻数据库（IFDB）开发所需的形式开发结果. 使用方差分析（ANOVA）、事后检验（最小显著性差异）、典型相关性和马氏距离对获得的数据进行统计分析. 分析结果（ANOVA）表明，亚麻品种的5个性状存在显著差异: 株高、技术长度、细长、千粒重和种子产量. 亚麻基因型变异范围: 总株长58.05 cm～92.8 cm; 技术长度44.7–78.6厘米; 杆厚; 1.42–2.18 mm; 细长: 246–474; 穗长: 10.05–21.55厘米; 穗分枝数: 3.4～6.2; 每株胶囊数: 5.15–19.7; 蒴果种子数: 6.24～7.86粒; 千粒重: 4.82 g～7.72 g. 调查结果可以为新品种的育种提供初始材料选择的重要步骤，也可以为企业家、私人消费者以及学生和科学家的研究提供信息.
