AbstractLinseed is one of the most important sources of valuable edible oil in temperature climate conditions. According to FAO (2016) linseed is cultivated over an area of 2.76 mln ha, of which 23.4% is in Canada, 10.7% in China and 10.6% in India. Amongst the 300 species of linseed belonging to the family Linaceae, the species Linseed (Linum usitatissimum L.) is the only one of significant agricultural importance. This species is found in two botanical varieties: Linum usitatissimum var. crepitans, which is an intermediate form between wild and cultivated, and Linum usitatissimum var. vulgare, with closed capsules at full maturity. Linseed occurs in two forms: spring and winter. The sprig form is more popular, but in Western Europe the popularity of cultivation of the winter form is still increasing. In Canada breeding programs for linseed (flax) were initiated in 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. Linseed requires medium to high soil quality and a sustainable level of mineral fertilization. Currently the average yield is low, ca 1.1 t ha-1, but the figure has slowly increased over the past 50 years. Linseed productivity depends on the level of agrotechnology, weather conditions, type of cultivar and their interactions. Linseed is cultivated mainly in pure stands, but can be cultivated in mixtures – previously with cereals and later with pulses. The method of linseed cultivation determines the seeds quality. This chapter discusses the productivity, agrotechnology and seeds properties of linseed with a focus on utilization of the crop.
