Oil flaxseed classification.

Linseed Extract INCI Name Linum Usitatissimum Extract Oil flaxseed Linum usitatissimum L.2n=30.Hu Ma Fatty acid alpha linoleic Omega-3 photo picture image Oil flaxseed as a agro plant in china normally divided into 3 types, one is mainly for fibre use, could be named as Fibrous Oil flaxseed (or fibre flaxseed ); one is mainly for oil processing use, could be named as Oil only flaxseed(or oil flaxseed); and the third one is for both fibre purpose and oil purpose.

 (1).Oil only flaxseed have lower individual plant height, base stem branches 4~8 sub-branch, and fruit 80~120 units every plant, net weight of 1000 kernels about 5~7 grams, higher oil ratio.

 Bigger Oil only flaxseed have bigger kernel than normal oil only flaxseed, lower individual plant height,net weight of kernel 1000unit could reach 11~13grams, oil ratio in kernel share 39~42%.

 (2).Oil flaxseed for both fibre purpose and oil use have a little higher individual plant height,base stem plant branches many,net weight of 1000 kernels about 4~6 grams, oil contain ratio normally 40~45%, fibre ratio of stem share 12~17%.

 (3).Fibrous Oil flaxseed (or fibre flaxseed ) stem slim and high, height 60~120cm, little sub branch or no sub branch, less sub branch from top, small anthotaxy. Small seeds, net weight of 1000 kernels about 3.8-4.5 grams,bearing period 70~80 days.

 Some scientists identified three closely related flax species and their hybrids: (Linum usitatissimum L., 2n = 30; L. angustifolium Huds., 2n = 30; and L. bienne Mill., 2n = 30) and their hybrids.

 In each case, the karyotype included metacentrics, submetacentrics, and one or two satellite chromosomes. Chromosomes of the three flax species were similar in morphology, size (1-3 microns), and C-banding pattern and slightly differed in size of heterochromatic regions. In all accessions, a large major site of ribosomal genes was revealed by hybridization in the pericentric region of a large metacentric. A minor 45S rDNA site was observed on a small chromosome in L. usitatissimum and L. bienne and on a medium-sized chromosome in L. angustifolium. Upon silver staining, a nucleolus-organizing region (NOR) was detected on a large chromosome in all species. In L. angustifolium, an Ag-NOR band was sometimes seen on a medium-sized chromosome. In the karyotypes of interspecific hybrids, silver-stained rDNA loci were observed on satellite chromosomes of both parental species. RAPD analysis with 22 primers revealed a high similarity of the three species. The greatest difference was observed between L. angustifolium and the other two species. The RAPD patterns of L. bienne and L. usitatissimum differed in fewer fragments. A dendrogram of genetic similarity was constructed for the three flax species on the basis of their RAPD patterns. Genome analysis with chromosome and molecular markers showed that L. bienne must be considered as a subspecies of L. usitatissimum rather than a separate species. The three species were assumed to originate from a common ancestor, L. angustifolium being closest to it.
