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.

Linola™ '947' flax (Linum usitatissimum L.) was the first low linolenic flax cultivar registered in 1993 in Canada. It had very good lodging resistance, was late maturing and produced seed with a very high oil content. In western Canada, '947' had yield similar to McGregor, its recurrent backcross parent. '947' has a yellow seedcoat. Key words: Flax, low linolenic acid, cultivar description

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.

Linola™ 989 is the second low linolenic flax cultivar registered in Canada. In western Canada, Linola™ 989 is significantly earlier maturing than Linola™ 947 and Flanders, and has a significant yield advantage over Linola™ 947 in the Black and Brown soil zones. Linola™ 989 is significantly higher yielding than Flanders in the Black soil zone of Saskatchewan and Manitoba. Both Linola cultivars are yellow seeded.

Low Linolenic

To improve oxidative stability of soybean oil and reduce off-flavours, we previously developed low linolenic acid, lipoxygenase-free (LLA.3lx) soybean germplasm. The objectives of this study were to characterize the patterns of inheritance and determine the relationships between the low linolenic acid (LLA) trait derived from the lines RG10 and PI 361088B and seed lipoxygenase nulls (3lx) from a triple null line OX948 that were used to create the new LLA.3lx germplasm. Reciprocal crosses between RG10 and OX948 and between PI 361088B and OX948 were made and populations derived from them were evaluated for their fatty acid profiles and seed lipoxygenases (LX) at the F2, F5 and F6 generations. Both RG10 and PI 361088B contain a single gene that controls linolenic acid (LA) content with alleles acting in an additive manner. No significant cytoplasmic effects were observed on LA content. The LLA trait was highly heritable in both RG10 × OX948 (RO) and PI 361088B × OX948 (PO) crosses and stable in different environments (Belize and Ontario, Canada). The three seed LX were each controlled by single genes, but lipoxygenase 1 (Lx1) and lipoxygenase 2 (Lx2) were tightly linked. No significant correlations were observed between LA content and seed LX. The simple and independent inheritance of LA and seed LX in these crosses should simplify breeding for soybean cultivars that are resistant to oxidative degradation.
