Cool, moist soils combined with deep seeding can have a dramatic negative effect on percent emergence and the time to emergence of flax seedlings. The effects of temperature (over a range of 5–15 °C) on seed germination, and seedling emergence from a sowing depth of 20 and 40 mm, were determined for seven cultivars of flax. Temperature had no effect on percent germination; however, the time for 50% of the seeds to germinate at 5 °C was on average 160 h compared with 30 h at 15 °C. The time for 50% of the seeds to germinate at temperatures less than 8 °C was the least for Andro and Vimy and the greatest for Dufferin, McGregor and Norlin. Temperatures less than 10 °C had a dramatic effect on seedling emergence from both seeding depths. On average, fewer seedlings emerged from the 40-mm seeding depth than from the 20-mm seeding depth. The time for 50% seedling emergence at 5 °C was on average 450 h for seeds sown 20 mm deep and 600 h for seeds sown 40 mm deep. In contrast at 15 °C, 50% of the seedlings for all seven cultivars emerged after 150 h from 20 mm and 180 h from 40 mm. At the cooler temperatures and 40 mm seeding depth, Vimy and Andro had the highest emergence rates, while Dufferin and Norlin had lowest emergence rates. This study demonstrates the importance of seeding depths when seeding into cool soils. Also genotypes such as Andro and Vimy are more likely to provide uniform stands when soils are cool and moist and when flax is seeded deep.

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.
