Abstract

Date-of-seeding experiments were carried on at Indian Head, Saskatchewan, from 1954 to 1960, using three late maturing varieties, Redwood, Rocket and B 5128, and two early varieties, Marine and Raja. The varietal yields varied much more among dates than among years. The highest yields from both early- and late-maturing varieties were obtained by planting early. Very late seeding generally resulted in extremely low yields of the late-maturing varieties, while the early-maturing varieties produced a paying crop. With the exception of the late dates of seeding, the late-maturing varieties outyielded the early-maturing varieties of flax.The number of seeds per boll appeared to be a stable varietal characteristic and there were distinct differences among some varieties.Date-of-seeding affected plant height, with all varieties being taller when seeded late. The number of days to maturity differed with dates of seeding but did not affect the ranking of varieties for this characteristic.
