Four of the most promising of the strains of selected fiber flax were sown in a field alongside some Blue-Blossom Dutch fiber flax, the variety com- monly grown for fiber both in the United States and in Canada. There was a superiority of at least 6 inches in height and in the length of fiber for all the selected flaxes over the unselected Blue- Blossom Dutch flax. The Sagi- naw variety, with an extra length of 8 inches, yielded 30 per cent more straw per acre than the Blue-Blossom Dutch; besides, since the stems were freer from flax wilt, it yielded a better qual- ity of fiber. Under actual field conditions the pedigreed fiber flax yielded one-third more fiber per acre than the commercial va- riety, Blue-Blossom Dutch flax, and this more than outweighs the only important advantage the commercial flax has over it— that of producing one-fifth more seed. (Fig. 9.) The results of a direct compari- son of these two varieties of flax are shown in Table 4. Since this pedigreed fiber flax, grown in this country for the last 12 years, maintains the su- periority shown in Table 4 over seeds freshly imported from Holland and Russia, it would not appear necessary to im- port fiber flax for seeding pur- poses, provided proper care is taken of the seed produced in this country. In this connec- tion it may be stated that observations during the last 10 years, both in experimental-plat and commercial sowings do not show that imported seeds have any advantage over those grown in this Fig. 8.—Plant-breeder's Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
