Their potential for dual-purpose production of oil and fibres was investigated. Linseed was grown according to current agricultural practice (seed DENSITY=450 m-2, mineral nitrogen at SOWING=50 kg ha-1) near Bonn (Germany) in 1995 &#8211; 1997. Fibres were mechanically isolated from pulled plants. Plant characteristics relevant for fibre production were highly variable. Fibre content of the technical stem, fineness and tensile strength (grip distance, GD=2 mm) ranged from 15.3 to 30.3%, 1.75 to 30.92 tex, 8.3 to 1226.5 MPa across genotypes and years. <\/p>\n<p>Corresponding medians were 24.4%, 10.25 tex, 445.0 MPa. Variability, attributed to genotype (g), year (y) and interaction genotypexyear (i) amounted to 0.0\/20.2\/55.9% (g\/y\/i) for the fibre content, 3.6\/58.1\/0.0% for fineness and 13.8\/31.0\/8.8% for tensile strength. Further, oil yield, straw yield and length of the technical stem were established for genotype assessment. <\/p>\n<p>These characteristics varied from 573.3 to 2238.9 kg ha-1, 2633.7 to 8062.8 kg ha-1 and 27.0 to 75.7 cm across genotypes and years. Corresponding medians were 923.9 kg ha-1, 5100.4 kg ha-1 and 49.2 cm. Here, variability caused by genotype (g) year (y) and interaction genotypexyear (i) was 0.1\/85.8\/0.9% (g\/y\/i) for oil yield, 2.8\/67.9\/4.5% for straw yield and 0.0\/0.0\/ 42.9% for length of the technical stem. Genotypes were grouped by cluster analysis. <\/p>\n<p>Assignment of genotypes to clusters was inconsistent between years confirming that variability of the characteristics investigated was mostly affected by year. On the basis of grouping, a rating scheme is proposed that allows to evaluate linseed genotypes for the use of oil as the main product and of fibres as a by-product.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In der Novemberausgabe des Wissenschaftsjournals Industrial Crops and Products berichten die Autoren Rennebaum et al. &uuml;ber die M&ouml;glichkeiten der Nutzung von &Ouml;llein.
