Determination of yield and quality performances of camelina [Camelina sativa (L.) Crantz] genotypes under mediterranean climate conditions
Project no. 21433 · Status: Kapanmış · 2020
Summary
<p>This research was conducted to determine the yield performance and fatty acid components of 33 <em>Camelina sativa</em> genotypes with different origins in Mediterranean climate conditions. The research, designed according to a randomized complete block design with three replications, was carried out in the fields of the Department of Field Crops at Ege University Faculty of Agriculture in Bornova, during the winter seasons of 2019-2020 and 2020-2021. In the study, plant height (cm), first branch height (cm), number of capsules per plant, number of seeds per capsule, thousand seed weight (g), yield (kg/ac), palmitic acid (%), stearic acid (%), oleic acid (%), linoleic acid (%), alpha-linolenic acid, and erucic acid (%) values were examined, and significant differences among genotypes were found at a statistical level.</p><p>When the average yields per hectare were examined for both harvest years, genotypes 28 (258.0 kg/ac) and 9 (237.6 kg/ac) stood out. In terms of other agronomic traits, genotype 2 (87.4 cm) excelled in plant height, genotype 25 (52.4 cm) in first branch height, genotype 1 (240.4 capsules/plant) in number of capsules per plant, genotype 35 (14.7 seeds/capsule) in number of seeds per capsule, and genotype 26 (1.51 g) in thousand seed weight. When the fatty acid components of the genotypes were examined, it was concluded that the levels of fatty acids in the genotypes did not vary across the years. However, the fatty acid values differed among genotypes for all fatty acid components. Among the saturated fatty acids, genotype 27 (6.05%) exhibited the highest value for palmitic acid, while genotype 14 (2.68%) showed the highest value for stearic acid. In terms of unsaturated fatty acids, genotype 16 (18.39%) had the highest oleic acid content, genotype 9 (20.71%) had the highest linoleic acid content, genotype 8 (39.52%) had the highest alpha-linolenic acid content, and genotype 25 (3.58%) had the highest erucic acid content. According to the research results, the erucic acid content in all genotypes was below the upper limit set by the Turkish Food Codex of 5%, indicating suitability for food consumption. Genotypes 28 and 9 were determined to be promising genotypes, as they were both leading genotypes in terms of seed yield per acre and suitable for human consumption in terms of erucic acid content. Therefore, genotypes 28 and 9 were identified as hopeful genotypes.</p><p><strong>Keywords:</strong> Camelina, yield, fatty acids, erucic acid, omega-3, omega-6, omega-9, Unsaturated oil acids.</p>
