Flax (Linum usitatissimum L.) is a poor biological competitor and so requires chemical weed control for optimal productivity. An alternative to current, relatively expensive combinations of herbicides might be to introduce into a commercial flax genotype, using Agrobacterium mediated transformation, a gene conferring tolerance to a non-selective herbicide. Here, we describe the transformation of Norlin flax with a PAT (phosphinothricin acetyl transferase) gene conferring tolerance to glufosinate, a non-selective herbicide (Harvest™, Ignite™, Agrevo). We also present results from a preliminary field trial, showing the efficacy of the PAT gene in conferring tolerance while not dramatically altering the normal agronomic traits of the parent cultivar. Key words:Linum usitatissimum, flax, transgenic, glufosinate, phosphinothricin, field trial, herbicide tolerance

Duguid, S. D., Rashid, K. Y. and Kenaschuk, E. O. 2014. Prairie Thunder flax. Can. J. Plant Sci. 94: 445–449. Prairie Thunder, medium-maturing oilseed flax (Linum usitatissimum L.), was released in 2006 by Agriculture and Agri-Food Canada, Morden Research Station, Morden, Manitoba. Developed from the cross AC Watson/FP1043 made in 1995, Prairie Thunder was evaluated in the Flax Cooperative Trials (2002–2004) before being registered in 2006. Prairie Thunder's desirable combination of improved agronomic traits, seed quality and superior wilt (Fusarium oxysporum Schlecht. f. sp. lini (Bolley) Snyder & Hansen) resistance should make this cultivar useful for producers and the flax industry.

Abstract The use of the technology of genetic modification (GM) in European agriculture and the food supply chain is currently controversial. Because of strong anti-GM technology sentiments, the use of ingredients derived from plants containing GM have largely been eliminated from foods manufactured for direct human consumption by the food supply chain in much of the European Union (EU). During the past year, the attention of those opposed to the technology has turned to the use of GM ingredients in livestock production systems by incorporation of GM soy and maize in animal feed. A discussion is presented of the key issues relating to this subject, focusing on how supplies of GM or non-GM products are segregated or how their identities are preserved. The discussion is centered on GM maize and soybeans into which agronomic traits, such as herbicide tolerance and/or insect resistance, have been incorporated. These are currently the only crops into which some varieties containing GM have been approved for use in the EU.

Duguid, S. D. and Rashid, K. Y. 2013. Prairie Sapphire flax. Can. J. Plant Sci. 93: 1271–1275. Prairie Sapphire, a medium-early maturing oilseed flax (Linum usitatissimum L.), was released in 2009 by Agriculture and Agri-Food Canada, Morden Research Station, Morden, Manitoba. Developed from the cross Macbeth/FP2030 made in 1998, Prairie Sapphire was evaluated in the Flax Cooperative Trials (2005–2007) before being registered in 2009. Prairie Sapphire's desirable combination of agronomic traits with its significantly improved oil and meal protein content should make it a useful cultivar for producers and the flax industry.

Yang, F., Liu, F.-h. and Rowland, G. 2013. Effects of diurnal temperature range and seasonal temperature pattern on the agronomic traits of fibre flax ( Linum usitatissimum L.). Can. J. Plant Sci. 93: 1249–1255. Three cultivars of fibre flax (Linum usitatissimum L.), Viking, Argos and Ariane, were used to study the effect on various agronomic traits of diurnal temperature ranges (DIF) and seasonal temperature patterns (STP) applied throughout the crop growth period. Diurnal temperature ranges were set at 5, 10 and 15°C with the same daily mean temperature and accumulated growing degree days (GDDa), under a parabolic STP. Seasonal temperature patterns were set following parabolic, anti-parabolic and quasi-horizontal configurations with DIF set at 10°C. The results showed that DIF or cultivar had a significant influence on the biomass, plant height (PH), stem diameter (SD), length of technical stem (LTS), weight of technical stem (WTS), fibre weight (FW), fibre content (FC) and seed weight per pot (SWp). Seasonal temperature pattern also had a significant influence on these traits except for WTS and FW. Significant interactions were observed between DIF and cultivar, affecting all traits with the exception of FW, and between STP and cultivar, affecting biomass, PH, SD and WTS. Diurnal temperature range set at 10°C was optimal for biomass, PH, SD, LTS, WTS, and FW, while DIF set at 5°C benefited FC and SWp. Among the different STP configurations, anti-parabolic pattern was optimal for biomass, PH, SD, LTS and FC, and the quasi-horizontal pattern best fit SWp. In conclusion, the combination of DIF set at 10°C and anti-parabollic STP provided the most favorable temperature conditions for fibre flax growth, which is the situation with winter flax production in Yunnan, China.

The desiccants diquat, glufosinate-ammonium, dimethipin and glyphosate were applied to flax when 44–84% of the capsules were green to reduce damage from subsequent frost. Beginning 3 d after desiccant application, plant samples were taken at 2–4 d intervals and exposed to a temperature at −20 °C overnight. Diquat application gave the most promising results, reducing the proportion of discolored seed and sometimes reducing loss of germinability, while resulting in a small yield loss compared with freezing of untreated plants. Key words: Flax, Linum usitatissimum L., desiccants, frost damage, seed quality, germination

Duguid, S. D., Rashid, K. Y., Busch, H. and Schaupp, H. 2014. AAC Bravo flax. Can. J. Plant Sci. 94: 153–156. Bravo, a medium maturing oilseed flax (Linum usitatissimum L.) was released in 2012 by Agriculture and Agri-Food Canada, Morden Research Station, Morden, Manitoba. Developed from the Flanders/Pacific made in 1995, AAC Bravo was evaluated in the Flax Cooperative Trials (2008–2010) before being registered in 2012. AAC Bravo's desirable combination of agronomic traits, particularly its significantly large seed size as compared with other commercially available cultivars, seed quality and disease resistance, should make it a useful cultivar for producers and the flax industry.

Abstract Understanding agronomic traits at a genetic level enables the leveraging of this knowledge to produce crops that are more productive and resilient, have better quality and are adjusted for consumer preferences. In the last decade, rice has become a model to validate the function of specific genes, resulting in valuable but scattered information. Here, we aimed to identify particular genes in rice related to traits that can be targeted by different mutation techniques in the breeding of crops. We selected gain of function, misfunction, and specific mutations associated with phenotypes of agronomic interest. The review includes specific trait-related genes involved in domestication, stress, herbicide tolerance, pathogen resistance, grain number, quality, weight, plant structure, nitrogen use, and others. The information presented can be used for rice and crops with similar or homologous genes to breed crops that require improvement to achieve more sustainable production in challenging farming conditions.
