Emergence of flax (Linum usitatissimum L) is affected by seed colour and seed linolenic acid concentration. The role of soil and soil microorganisms in this relationship was studied in near isogenic populations for seed colour and linolenic acid level. In growth chamber experiments, the emergence of flax from autoclaved soil was greater than from non-autoclaved soil. This effect was greater for yellow seed than brown seed. Seed with high (50%) levels of linolenic acid had greater emergence than seed with low (2%) levels of linolenic acid in both soil types. The protective effect of brown seed and high seed linolenic acid levels on emergence in flax was confirmed. Key words: Seed colour, linolenic acid, soil microorganisms, flax

McGregor flax (Linum usitatissimum L.) seed was treated with ethyl methanesulphonate (EMS) and the resulting M1, M2, M3 and M4 progeny were screened for linolenic acid mutants, using the half-seed technique. A stable low-linolenic acid (2%) mutant was found in the M4. The low linolenic character is controlled by recessive alleles at two independent loci, apparently the result of a rare double mutation.

Changes occurring in stored solin/flax cultivars over 6 mo at temperatures ranging from 10 to 35 °C and moisture contents of 8.0, 9.5, 11.0 and 12.5% were observed. The cultivars were NorLin, McGregor, FP1001 (high linolenic acid), LinolaTM 947 (solin) and LinolaTM 989 (solin). Oil composition in all cultivars changed only slightly over 6 mo with a significant increase in palmitic acid. Doubling of free fatty acid levels was considered an indicator of quality deterioration. The deterioration occurred in 6 mo at 8% MC and 20 °C in FP1001 and in NorLin, McGregor, and LinolaTM 947 at 25 °C; LinolaTM 989 could be stored at 30 °C. LinolaTM 989 could be safely stored at moderately higher temperatures at a given moisture level than LinolaTM 947. Visible mold with corresponding germination loss was usually associated with Aspergillus glaucus group infection. Stored-product insects that could survive and develop on the solin/flax were the red flour beetle, Tribolium castaneum (Herbst), the confused flour beetle, T. confusum J. du Val, the sawtoothed grain beetle, Oryzaephilus surinamensis (L.) and the merchant grain beetle, O. mercator (Fauvel).In general, LinolaTM 947 and FP1001 were slightly more difficult to store than the other cultivars but there was no consistent difference between solin and flaxseed.

AbstractThe aim of our work was to characterize linseed (Linum usitatissimum L.) genotypes divided into groups with high and low content of alpha-linolenic acid (ALA). Out of 32 linseed genotypes, 68.75 % represented high alpha-linolenic genotypes and 31.25 % were genotypes with low ALA content. Proportional representation of fatty acids was realized according to the norm (Czech Office for Standards, Metrology and Testing, 1994). Oil content was analyzed according to the internal methodology of Agritec Ltd., based on the norm (Czech Office for Standards, Metrology and Testing, 2011). The content of total fat ranged from 36.22 % to 46.35 %, that of ALA from 1.10 % to 65.20 %, and that of linoleic acid (LA) from 11.10 % to 75.00 % in the analyzed seed samples within all groups. The genotypes were divided also according to the seed color and a linear correlation between all three parameters within these groups was observed. Negative linear dependence was confirmed between parameters; ALA and LA content in the groups: high ALA brown seed (p < 0.0001; correlation coefficient (r) = −0.70), and high ALA yellow seed (p < 0.001; r = −0.36). Also, positive linear dependence between the total fat and the LA content in the groups: low ALA brown seed (p < 0.001; r = 0.34); low ALA yellow seed (p < 0.0001; r = 0.62), was found.

Mutant Genes

Two flax (Linum usitatissimum L.) mutants having reduced linolenic acid content in their seed oil (M1589 = 19.1% linolenic; M1722 = 23.4% linolenic) were crossed to determine whether further reductions could be achieved by recombination of the mutant genes. Extensive transgressive segregation was evident in the F2 for both linolenic acid (1.2–36.6%) and linoleic acid (14.7–55.2%), which were strongly negatively correlated (r = −0.97). F2 plants homozygous for both the M1589 and M1722 mutations had very low levels of linolenic acid (<2%) and high levels of linoleic acid (>46%).Key words: Flax, linseed, Linum usitatissimum, linoleic acid, linolenic acid, seed oil

In Poland the cultivation of the fibrous form of flax (<em>Linum usitatissimum </em>L.) is dying out, but the acreage of its oilseed form, linseed, which provides seed (<em>Semen lini) </em>used in therapy and being a source of -linolenic acid, is expanding. Nowadays, linseed is grown in 64 countries of the world, but yield levels in these countries vary greatly. Under European conditions, seed yield of linseed shows high variation, which is evidence of little knowledge of the biology of this plant and the lack of precise cultivation solutions in agricultural technologies used. A major reason is the difficulty in obtaining optimal crop density. A sparse crop results in low above-ground biomass yield, which is translated into insufficient crop yields. The selection of highly productive domestic and foreign varieties can partially increase linseed yield; apart from some domestic varieties, the Canadian cultivar 'Flanders' and the Hungarian cultivar 'Barbara' are positive examples in this respect. There is a possibility of effective selection at early stages of linseed breeding, which bodes well for the prospect of obtaining highly productive varieties with normal or very low -linolenic acid content.

Background. Almost all described flax (Linum usitatissimum L.) biodiversity is presented in VIR genetic collection(GC). Materials and methods. 316 lines from GC belonging to 5 subspecies (indo-abyssinicum, hindustanicum, eurasiaticum, mediterraneum, transitorium) were characterized by morphological traits (MT), for some of them Mendel’s genetic control was evaluated. Results. MT groups, genotypes typical for each of subspecies are revealed, but appearance of other phenotypes cannot be excluded, because subspecies can differ only in frequency of their occurrence. The genetic analysis was carried out. It expanded the list of MT genes. It was shown that many lines have similar mutations of MT regardless of their origin. Many MT genes are promising or already use in breeding for example YSED1 and ysed (yellow seed), pf-ad (pink flower, yellow seeds), dlb3 (pale blue flower), sfbs1 (white deformed flower). Soon lines carrier s1 gene (anthocyanin biosynthesis inhibitor), will be used because mucilage from seeds s1s1 has special polysaccharide compound and with wf1 (white flower) gene which is linked with early flowering. The linkage between the genes controlling dark blue flower (sfc6, sfc10) and yellow seeds (ysed2) was found, which must be taken into account while breeding for yellow seed. Conclusion. The old landraces of GC can serve as source for any direction of breeding.
