Rainfed Conditions

Three fibre flax (Linum usitatissimum L.) cultivars, Hera, Natasja and Reina, and the oilseed cultivar Dufferin were tested at Hagen in 1977 and 1978 under rainfed conditions, and at Saskatoon in 1977 and Outlook in 1978 under irrigation. The tests included four rates of nitrogen fertilizer (0, 50, 100 and 200 kg N/ha) and three seeding rates (50, 100 and 150 kg/ha). In addition, these four cultivars plus the fibre cultivar Budalak were evaluated under rainfed conditions at Saskatoon in 1977. In every test, except the Saskatoon rainfed, straw yields of the fibre cultivars were significantly greater than of Dufferin. Nitrogen fertilizer increased straw production and straw yields responded linearly to seed rate increases. Without exception, Dufferin had the greatest yield of seed and had approximately 3% higher oil content.

CDC Bethune, is a medium-late-maturing oilseed flax (Linum usitatissimum L.) developed by Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan. This cultivar has medium oil content, medium oil quality, medium seed size, good lodging resistance and high yield when seeded early in the Black and the Brown Soil zones of the prairies. It is immune to North American races of rust caused by Melampsora lini and moderately resistant to wilt caused by Fusarium oxysporum f. sp. lini.

Maturity Rating

CDC Buryu, a late maturing oilseed flax (Linum usitatissimum L.), was registered in 2016 by the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan. This cultivar had yield (106%) comparable to CDC Bethune and a maturity rating equal to Flanders in all soil zones of the Northern Prairies. The yield advantage over CDC Bethune was greater (>8%) in the Brown soil and Black soil zones of the Northern Prairies. It had medium oil content, oil quality, and seed size and good lodging resistance. It is immune to North American rust (race 371) caused by Melampsora lini and moderately resistant to wilt caused by Fusarium oxysporum f. sp. Lini and powdery mildew caused by Oidium lini.

Variation Patterns

Germplasm of 153 flax (Linum usitatissimum) accessions from 24 countries held at Plant Gene Resources of Canada (PGRC) was evaluated for resistance to fusarium wilt (Fusarium oxysporum), anthracnose (Colletotrichum lini) and pasmo (Septoria linicola). The screening was conducted at the All-Russian Flax Research Institute (VNIIL) at Torzhok, Russia, over 3 years for fusarium wilt and anthracnose, and over 2 years for pasmo. A disease severity index ranging from 0% (no infection) to 100% (heavy infection) was calculated based on observations after artificial inoculation with the pathogens in the greenhouse (fusarium wilt) or in field nurseries (anthracnose and pasmo). The average disease severity index for fusarium wilt was 56.6 ± 34.4% (range 0–100.0%), for anthracnose 59.8 ± 8.1% (range 43.8–83.9%) and for pasmo 74.2 ± 11.8% (range 27.3–100.0%). The variation of disease severity indices among the years and within each accession was highest for fusarium wilt. Higher than average resistance for all three diseases was found in accessions from East Asia, while germplasm from the Indian subcontinent showed considerably lower than average resistance. Germplasm from North America and South America (mostly linseed) displayed above average resistance to fusarium wilt, while European accessions (mostly fibre flax) showed lower than average resistance to this disease. The different resistance levels reflected the improvements made by plant breeding and differences in the environments under which the germplasm accessions evolved. Accessions with potential use in linseed and fibre flax breeding were identified.

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.
