“…Two different flax cultivars of different height classes were used in this trial: cultivars CDC-Sorrel and Prairie Grande. CDC Sorrel is a tall cultivar that grows to 66.5±3.5 cm (Canadian Food Inspection Agency, 2016a) while Prairie Grande is a short cultivar that typically grows to 54.1±5 cm (Canadian Food Inspection Agency, 2016b; Duguid et al, 2014). All seed used for this experiment was untreated, breeder seed sourced from the same seed lot.…”

“…Although there were clear effects on yield, there were no significant interactions between main factors for TSW, as cultivar height was the only factor that affected TSW with the tall cultivar 8% greater than that of the short cultivar. This difference is likely a function of the inherent differences in seed size between the two cultivars (Duguid et al, 2014;SeCan, 2016).…”

Integrating Cultural Practices with Herbicides Augments Weed Management in Flax

Core Ideas Current weed management strategies in flax are limited.A multi‐factor weed management system is needed to control herbicide‐resistant weeds.Combining several factors has a greater impact on crop‐weed competition than any factor alone.The best combination is a competitive cultivar, seed early, high seeding rate, and use an in‐crop herbicide. Flax (Linum usitatissimum L.) is an important crop with value in both food and industrial markets. However, flax competes poorly with weeds and as a result, flax yield can be severely inhibited by weed competition. Factors that favor crop competitive ability will have great value in improving weed management in flax. This research sought to identify different combinations of seeding date (early vs. late May), seeding rate (400 vs. 800 seeds m−2), cultivar height (short vs. tall), and herbicide (present vs. absent) that could improve the competitive ability of flax. Field studies were conducted across western Canada over 3 yr from 2014 to 2016. Results showed that seeding a tall cultivar at a high seeding rate in early May combined with an in‐crop herbicide application increased crop establishment by 210 plants m−2. This in turn increased aboveground crop biomass and seed yield by as much as 549 and 617 kg ha−1, respectively. This combination of factors significantly reduced aboveground weed biomass by 50 kg ha−1, although no single factor or combination of factors affected weed seed fecundity. By seeding competitive flax cultivars at higher rates earlier in the growing season, and by combining this with an in‐crop herbicide, producers can develop sound cropping systems that provide more competitive flax crops and another profitable cropping option.

CDC Plava oilseed flax (Linum usitatissimum L.), registered in 2015 by the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan, is targeted to the shorter growing season, Dark Brown, Black, Grey, and Dark Grey soil zones of the Northern Prairies. This cultivar has a high seed yield (106%) compared with cultivar (cv.) CDC Bethune and a medium maturity rating equal to cv. Prairie Thunder. It has medium oil content (47.0%), alpha-linolenic acid content (57.8%), seed size (6.1 g thousand seed weight, TSW), and good lodging resistance. It is resistant to North American races of rust caused by Melampsora lini, and moderately resistant to wilt caused by Fusarium oxysporum f. sp. lini.

Pedigrees and genetic base of flax cultivars registered in Canada

et al. 2016

Flax is an important oilseed crop with industrial, animal, and human nutrition uses. Breeding programs for linseed and fibre flax were initiated in Canada in the early 1900s. A total of 82 flax cultivars have been registered in Canada since 1910, including 24 cultivars introduced from foreign countries and 58 cultivars developed by Canadian breeders. This study collated pedigree data of Canadian flax cultivars and quantified their genetic base via pedigree analysis and coefficient of parentage (CP). A fairly high mean CP of 0.14 was observed between all registered cultivars; this value was even higher (0.23) when only the 46 cultivars released from 1981-2015 were considered. The registered cultivars traced back to 46 ancestors; 72% originated from foreign countries and contributed 83% of the genetic base of all cultivars, illustrating the dominant role played by foreign germplasm in the genetic improvement of Canadian flax. The top 11 ancestors contributed 70%-93% of the genetic base of modern flax cultivars released in the last three decades and formed the core gene pool of Canadian flax cultivars. The genetic base of Canadian cultivars is relatively narrow, although it has gradually expanded, especially in the last two decades. Broadening the genetic base through the introduction of new exotic germplasm is needed to invigorate the gene pool of Canadian flax breeding programs.Key words: flax, cultivar, pedigree, ancestor, genetic base, Canada.Résumé : Le lin est un important oléagineux utilisé à des fins industrielles ainsi que pour l'alimentation humaine et animale. Les premiers programmes d'hybridation visant à accroître la production de graines et de fibres de cette culture remontent au début du vingtième siècle. Quatre-vingt-deux variétés de lin ont été homologuées au Canada depuis 1910, ce qui comprend 24 cultivars de l'étranger et 58 créés par des améliorateurs canadiens. Cette étude rassemble les données généalogiques sur les variétés canadiennes et en quantifie la base génétique d'après leur ascendance et leur coefficient de parenté (CP). Les auteurs ont relevé un CP moyen relativement élevé (0,14) entre les variétés homologuées; le CP est encore plus élevé (0,23) quand on ne tient compte que des 46 cultivars homologués entre 1981 et 2015. Les variétés homologuées ont 46 ancêtres. Soixante-douze pour cent ont pour origine des pays étrangers et représentent 83 % de la base génétique des cultivars, signe du très grand rôle que le matériel génétique exotique a joué dans l'amélioration du lin canadien. Les onze principaux ancêtres ont fourni de 70 à 93 % de la base génétique des variétés de lin contemporaines, homologuées au cours des trois dernières décennies, et constituent le principal réservoir de gènes des cultivars canadiens. Les variétés canadiennes de lin se caractérisent par une base génétique assez étroite, bien que celle-ci se soit graduellement élargie, surtout au cours
