SUMMARYThe effect of the field application of chlormequat on the growth, yield and seed oil content of Brassica juncea grown under irrigated and rainfed conditions was evaluated for three consecutive crop seasons. Foliar application at the flower initiation stage increased the number of primary branches, number and length of siliquae, weight of seeds and seed oil content. Chlormequat (50 AS) applied at 80 ml ha−1 increased seed yield by more than 50%. The increase was greater in unirrigated crops.

Safflower seeds provide an oil rich in mono and polyunsaturated fatty acids. Its adaptation to drought and high temperatures makes it an alternative for the development of oleaginous crops in semi-arid areas. This study examines the oil content and the chemical composition of seed oil from three safflower accessions (Gila, Halab, Touggourt) cultivated over three years (2015, 2016, and 2017) in a semi-arid area in Tiaret (West of Algeria). Under these semi-arid conditions, characterized by low rainfall and high temperatures, seed oil content remained relatively high and was composed mainly of unsaturated fatty acids, with their ratio to saturated fatty acids reaching an average value of 9. Seed oil content varies between 22.8% and 28.4% among the genotypes and throughout the three years. The extracted oil consists essentially of unsaturated fatty acids, linoleic and oleic acids, poly and monounsaturated, respectively. Their contents over the three years vary between 75% and 79.3% for linoleic acid and between 10.2% and 14.7% for oleic acid. The saturated fatty acids content of the oil reached a maximum value of 9%. They consist mainly of palmitic acid, of which the average genotypic content varies between 6.6% and 7.15% depending on all grown years. The results obtained may assist in better understanding the response of cultivars under rainfed conditions and could be helpful for breeders with regards to introduction into selection programs.

Cucumber (Cucumis sativus) seed oil has the potential for use as an edible oil and as a pharmaceutical, cosmetic, insecticidal, and industrial product. In this study, we investigated, for the first time, the effect of cultivar and season on seed number, oil content, and fatty acid profiles as well as their proportions in different cucumber cultivars. We examined the effects of spring and autumn seasons on seed oil content and fatty acid composition in 46 cucumber cultivars and one wild species of cucumber (C. anguria) grown in greenhouse experiments in 2013 and 2014. Seed oil was determined using the Soxhlet method and fatty acids using the gas chromatography-mass spectrometry method. Seed oil content in the cucumber seeds ranged from 41.07% in ‘Hazerd’ to 29.24% in ‘Lubao’ while C. anguria had 23.3%. Fatty acids detected were linoleic (C18:2), palmitic (C16:0), oleic (C18:1), stearic (C18:0), linolenic (C18:3), behenic (C22:0), arachidic C20:0), lignoceric (C24:0), eicosenoic (C20:1), palmitoleic (C16:1), and myristic (C14:0), among other unidentified fatty acids. The results showed significant effects of cultivar genotype, growing season, and interactions on the variables examined. The content of seed oil and fatty acids differed significantly among the cultivar genotypes. Spring-grown cucumbers had higher quantities of oil than the autumn-grown cucumbers. The content of fatty acids (mainly palmitic, palmitoleic, stearic, oleic, eicosenoic, and lignoceric) also was higher in spring. In autumn there were more seeds, and higher linoleic, linolenic, and other unspecified fatty acids. The higher the oleic acid content the lower was the linoleic acid indicating a strong negative relationship in these two fatty acids. The higher the seed oil content the higher was linoleic and oleic indicating a positive relationship between the seed oil and the two fatty acids. Results of this study provide important information applicable in improving management and production of cucumber seed oil especially considering its versatility in uses. Furthermore, the wide range of fatty acids found in the studied cucumber cultivars could be used in the production of novel industrial oils through genetic engineering.

Carbon dioxide emissions by the transportation sector are major contributors to global climate change. Lower CO2 emissions by the transportation sector are linked to the use of renewable fuels including biodiesel. Canola has high seed oil content, adaptation to temperate climates and favorable fatty acid composition, which make it a preferred feedstock for biodiesel production. Doubled haploid (DH) line, random inbred (RI) line and consensus genetics maps for mapping populations derived from Polo × Topas were developed. The DH line-based genetic map was then used for the identification and tagging of quantitative trait loci (QTL) controlling seed oil biosynthesis. This genetic map consisted of 620 loci identified using several different types of molecular markers, and covered a map distance of 2241.1 cM with marker saturation of 3.7 cM. The phenotypic data on the mapping population for seed oil content and component fatty acids were collected from four-environment replicated field trials. One hundred and thirty-one QTL for various fatty acids in canola oil and 14 QTL for oil content were identified. These QTL, combined with marker-assisted selection, may assist breeders in their attempts to develop canola lines with improved oil quality, oil content and oil production per hectare for biodiesel production.

Seed Oil Content

Citrullus colocynthis has been garnering interest in recent times as a potential biodiesel feed stockcrop due to its high seed oil content and its natural adaptation to drought The variability seed oil content (OC), Oil yield (kg/ha) (OY) and fatty acid composition were investigated for 12 accessions collected in different localities in Morocco. Analysis of the data revealed high variability among the accessions, with seed oil content ranging between 17.1 and 24.3 % of seed weight and Oil yield from 35.3 to 172.7 kg/ha. The predominant fatty acid of the seed oil was linoleic acid, C18:2, ranging from 67.0 to 73.0 % of total fatty acids and the average values of unsaturated fatty acids vary between 75.25 and 81.94 %.The wide range of variations found in this study for the traits measured offers the possibility of genetic improvement to develop cultivars for biodiesel production compatible with sustainable and ecological agriculture.
