Seed Characteristics

Five flax (Linum usitatissimum L.) cultivars, Dufferin, McGregor, Linott, NorLin and NorMan were grown in the field in 1985, 1986 and 1987 at seeding rates of 200, 400, 600 and 800 seeds m−2. Averaged over all cultivars and years, as seeding rate increased from 200 to 800 seeds m−2, maturity was hastened 2.1 d, seed weight decreased 0.16 g 1000−1 seeds, oil content decreased 0.6%, iodine number decreased 1.3 units and volume weight was not markedly changed. Lodging increased and basal branching decreased from 1.68 to 0.18 branches per plant as seeding rate increased. Plant height increased 0.6 cm from the 200 to the 400 seeds m−2 rate then decreased 1.8 cm from the 400 to the 800 seeds m−2 rate. Seed yield increased from 110 to 124 g m−2 as seeding rate increased from 200 to 600 seeds m−2, then decreased to 121 g m−2 at 800 seeds m−2. Although yields of the five cultivars varied somewhat in their response to seeding rate and year, most yielded near optimum at the 600 seeds m−2 seeding rate.Key words: Flax, Linum usitatissimum L., seeding rate, lodging

The influence of the level of mineral nutrition and rate of seed sowing on yield and fatty acid composition of linseed (Linum usitatissimum L.) in the Non-chernozem zone of Russia was studied. It was shown that the level of mineral fertilizers N - 90, P2O5 - 60, and K2O - 60 kg/ha under the rate of sowing of 8 million seeds/ha provided maximum seed yield of 1.94 t/ha. A clear correlation between oil content and rate of sowing has not been established. Under an increasing level of mineral nutrition, oil content was slightly increased. The composition of oil was slightly changed under the influence of the studied factors.

Thirty-six genotypes including eight parents and their 28 crosses developed in diallel fashion excluding reciprocals were used to studied their stability performance over six contrasting environments viz., early, normal and late sown under rainfed and irrigated conditions for seed yield and its contributing characters. Genotype x Environment interaction and Linear component of G x E interaction were showed significant for all the characters except plant height, secondary branches per plant and biological yield per plant under study. The parents Meera and PA2 showed stable performance for two characters and rest of the genotypes showed stable performance for one character over a range of environments under study. The cross Meera x RL13161 and RL15583 x KBA3 showed stable performance for seed yield and two crosses RL13161 x KBA3 and RL15583 x KBA3 showed stable performance for oil content and rest of four crosses showed stable performance for other characters.

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.

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
