Linum Usitatissimum L

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.

This study was carried out to determine the efficiency of nitrogen (N) doses (0, 30, 60, and 90 kg N ha−1) under supplemental potassium (K) application (50 kg K2O ha−1) on black cumin in 2011 and 2012. The results showed that increased N levels resulted in increasing seed yield and N and K contents in seed, while oil content decreased. The seed yield and oil yield were peaked at the doses of 60 kg N ha−1and 50 kg K ha−1. An increase in N doses caused a reduction in oil content regardless of K supply. Saturated fatty acids and oleic acid were slightly increased by K application, while minor changes in linoleic acid were detected. It was concluded that 60 kg N ha−1with supplemental K application should be advised for enhancement in seed yield, oil yield, and N and K contents in seeds of black cumin without significant changes in fatty acid composition.

Ridomil MZ alone or Ridomil MZ followed by protectant fungicides was tested to manage white rust (Albugo candida) (Pers. ex Lev.) Kuntze on Brassica juncea L. var. RL-1359, sown at the normal time in 1989–90 and 1990–91 and under delayed sown conditions in 1990–91 at 2 different geographical locations of the Punjab state. Two spray applications of aqueous suspension of Ridomil MZ at 450 g a.i./ha or 1 foliar application of Ridomil MZ at 450 g a.i./ha, followed by another spray of Dithane M-45 at 600 g a.i./ha or Blitox-50 at 375 g a.i./ha at 15- or 20-day interval to a 70-day-old crop significantly reduced both foliage and floral infections. These treatments significantly increased the seed yield over control and other treatment combinations, without having an adverse affect on the oil content and fatty acid composition of the oil. The same fungicide regime was effective to control white rust when applied to a 50- or 60-day-old crop under delayed sown conditions. The seeds harvested from the plots treated twice with Ridomil MZ exhibited no detectable residue of metalaxyl and mancozeb. The timing of application of these fungicides may be critical in the control of white rust, particularly in the late sown crop.

Low Levels

Significant variation in seed weight, oil content and fatty acid composition was found both between and within varieties in a diverse collection of 214 Linum usitatissimum accessions. Parent-offspring correlation analysis indicated that at least a proportion of the variation within several varieties was due to genetic heterogeneity. Lines were identified that had up to 46 % oil, compared with the 40 % present in the current Australian cultivar, Glenelg. High oil content was consistently associated with larger seeds. Oleic acid and linolenic acid varied between 13.3 and 25.2%, and 45.5 and 64.2 %, respectively, and were strongly negatively correlated within and between all varieties tested. The level of variation is insufficient to develop lines with less than 5 % linolenic acid by conventional hybridization and selection techniques. It is concluded that mutation breeding and interspecific hybridization are more promising approaches to the breeding of linseed genotypes containing low levels of linolenic acid.

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
