Chilling Treatment

The effect of a 5 °C chilling treatment at the seedling stage on days to flower, yield and oil quality and quantity was determined for seven cultivars of flax (Linum usitatissimum L.). Three days of chilling delayed flowering in Dufferin, McGregor and NorLin, whereas 5 d of chilling delayed flowering in all cultivars except Andro and Noralta. Seven days of chilling reduced the seed yield of only McGregor, Norlin, NorMan and Vimy. The effect of a 40 °C heat stress at the flowering stage on yield and oil composition was determined for the same seven cultivars. A heat stress of 40 °C for 3 d reduced the seed yield of NorMan, whereas, a 5 d stress reduced the seed yield of all cultivars except McGregor and Noralta. The composition of the oil was not affected by the heat stress. These results suggest genetic variability exists among flax cultivars for tolerance to chilling and heat stresses. Controlled tests can be used to select superior stress tolerant genotypes. Key words: Flax, chilling, heat, flowering, yield

Valuable Alternative

Traditional oilseed crops, such as linseed (<em>Linum usitatissimum</em> L.), may represent valuable alternative crops in cropping systems dominated by cereals, due to their adaptability to poor soils and to their high economic value related to the interesting quality of the oil, which is being increasingly appreciated by consumers and industry. The aim of this study was to test the adaptability of linseed to the inland marginal areas of Tuscany, and to explore the levels of crop yield and oil quality which can be achieved in hilly and lowland environments. For three years (2011-2014), experimental open fields (1- 5 ha each) were established and monitored in six commercial farms located in the inland countryside of Pisa province, Tuscany, Central Italy. The effect of environment (hilly and plain areas) was assessed in terms of yield and yield components as well as oil content and composition. Interestingly, seed yield and biomass production were very stable over years in the two areas of cultivation, irrespectively of yearly differences in weather conditions. As expected, higher yields were obtained in plain than in hilly areas. Regarding oil composition, oil extracted from linseed grown in plain environments was richer in linolenic acid, while, oppositely, both oleic and linoleic acids were more abundant in oil from hilly areas. Definitively, our results demonstrated that linseed might be a valuable alternative to cereal crops for marginal lands of Tuscany and, more in general, of Central Italy.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.

Iron And Calcium

Linseed (Linum usitatissimum L.) is considered as a nutritious food because of exceptionally high alpha-linolenic acid (ALA) content, dietary fiber, quality protein and phytoestrogens. It is rich in minerals (100 g of seeds contain 350-431 mg of magnesium and 236- 250 mg of calcium) and has very low amount of sodium. It also contains anti-nutritional factors, especially phytic acid that interferes with the bioavailability of nutrients like calcium and iron. Fermentation increases the nutritional quality of foods by reducing anti-nutritional factors. Probiotic cultures viz., Lactobacillus acidophilus, Bacillus mesentericus and lactic acid bacterial isolate LAB-3 were used to produce fermented linseed beverage and the quantity of phytic acid, bioavailability of iron and calcium were estimated. Bioavailability of iron and calcium increased by fermentation. The highest bioavailable iron and calcium were observed in L. acidophilus fermentation (4.40 mg and 250.41 mg /100 g seeds, respectively) followed by LAB-3 and Bacillus mesentericus compared to raw seeds that contain 0.89 mg of iron and 125 mg of calcium /100g of seeds. Phytic acid content was high in raw seeds (1392 mg /100 g seeds) and fermentation with L. acidophilus recorded 856 mg phytic acid /100 g seeds resulting in 38.51 % reduction. LAB-3 and B. mesentericus showed approximately 32 % reduction in phytic acid content. The reduction in phytic acid content is significantly high. Fermentation using probiotic bacteria enhanced the bioavailability of iron and calcium by reducing phytic acid. Hence, this study leads to a conclusion that, microbial intervention can be adopted to reduce the anti-nutritional factors and enhance the nutritional quality of linseed.

AC Emerson, a medium-early maturing oilseed flax (Linum usitatissimum L.), was released by Agriculture and Agri-Food Canada, Agri-Food Diversification Research Centre, Morden, Manitoba, in 1994. The cultivar has high oil quality, medium-large seed size and was high yielding in both early and late seeding tests in the Black and the Brown Soil zones of Manitoba and Saskatchewan. Because of its chlorosis tolerance, it is particularly well suited to the calcareous soils of Manitoba. 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.
