The oil flax cultivar Y 220 is developed by a method of individual selection from a line k4165 at severe background after 6-field flax monocrop. It was estimated by resistance to fusariose in epicentrum of fusariose infection and to flax sickness at monocrop cultivation. Due to results of variety trials for 2019–2020, the cultivar Y 220 exceeded the standard cultivar FLIZ by yield by 0.77 t per ha. Plant height is 80–90 cm. Vegetative period is 75–80 days. Weight of 1000 seeds is equal to 6.02–6.06 g. Seeds color is brown. Oil content is 44.4%; linolenic acid content is lowered (23.3%). The cultivar Y 220 is differed with full resistance to flax sickness and high field resistance to fusarium wilt. This makes it possible to cultivate it in short crop rotations and at monocrop.

The influence of transplanting time on the growth of evening primrose (Oenothera biennis L.) was investigated for 3 yr. Delaying transplanting reduced the yield of seed in two of these years. The amount of oil in the seed was not influenced by time of transplanting, and only in one year did the γ-linolenic acid content of the oil decrease with delays in transplanting. Key words: Evening primrose, transplanting date, oil content, γ-linolenic acid

Abstract Background Oil and five main fatty acid content(especially linolenic acid content (LNA) )are six main quality traits in flax, and also the important target traits in flax breeding. However, the reports on genetic map construction and QTL mapping of linolenic acid content in flax are limited, which results in low accuracy and efficiency of quality breeding in oil flax. Construction the genetic linkage map and location the QTLs to discover the stable genetic QTLs sites related to oil content and fatty acid content, so as to provide targeted targets for breeders and improve breeding efficiency. Results In this study, a final integrated map consisting of 2,239 single nucleotide polymorphism (SNP) markers on 15 linkage groups (LGs) with an average distance of 0.46 cM between adjacent markers was generated using genotyping-by-sequencing (GBS) technique. A total of 21 quantitative trait loci (QTL)s for the six traits, i.e., palmitic acid content (PAL), stearic acid content (STE), oleic acid content (OLE), linoleic acid content (LIN), linolenic acid content (LNA), and oil content (OIL) in the RIL population under three environments. One QTL cluster harbored two QTLs for LIN and LNA trait, respectively was also identified. Especially, QTL qLIN-Group12-2 for LIN and QTL qLNA-Group12-2 for LNA on chromosome 12 were detected in multi-environments. Conclusions A high-density SNP genetic map with total 2239 markers was constructed with GBS technique, The total genetic distance of the SNP map was 1032.90 cM, with the average genetic distance of 0.46 cM per marker. A total of 21 quantitative trait loci (QTL)s for the six traits under three environments were determined. One QTL cluster harbored two QTLs for LIN and LNA trait, respectively was also identified. QTL qLIN-Group12-2 for LIN and QTL qLNA-Group12-2 for LNA on chromosome 12 were detected in multi-environments. These results provide more information for determining the seed quality related candidate genes and contribute to the marker-assisted selection in flax breeding.

Crambe Abyssinica

Crambe (Crambe abyssinica Hochst) is an oilseed crop in the Brassicaceae family. Crambe’s ability to survive in diverse environmental conditions, its unique oil composition, the high oil content, suitability for the production of slip agents for plasticizers, the capacity to be easily included in common crop rotations, and its adaptability to equipment used for small grain cultivation has renewed the interest in this emerging crop. Crambe is considered one of the main sources of erucic acid, which can be up to 60% of its seed oil content. Erucic acid (C22:1) is a fatty acid with industrial importance since it is used to produce erucamide, key ingredient in the plastic industry. Inclusion of crambe into crop rotations can be beneficial because of its short life cycle, low fertility requirements, resistance to pest and diseases, and relative drought tolerance. Currently high erucic acid rapeseed (Brassica napus L.) (HEAR) is the principal source for erucic acid. However, the risk of contaminating food quality rapeseed (i.e., canola) by cross-pollination and the negative impact on climate, due to high inputs, are potential limitations to expand HEAR cultivation. Crambe has thus great potential to, at least, partially replace HEAR as a source of erucic acid, if the current knowledge-gap in agronomic management and crop improvement (seed yield and quality) can be addressed. Seed yield needs to be increased to be able to compete with HEAR. In addition, reducing glucosinolates and fiber in crambe meal may increase its inclusion in monogastrics rations. The objective of this review was to compile and summarize new and existing information on agricultural practices in crambe production and management to identify gaps in knowledge and areas for future research to increase the cultivation of crambe.
