Oil Composition

Aim. Main aim of this research was a comparison of fatty acid composition for seed oils from oil radish breeding forms and varieties produced in Natl. Botanical Garden of Natl. Academy of Sciences of Ukraine. Methods. Biochemical analysis of oil content as well as chromatographic analysis of fatty acid composition of oil radish and its genotypes were conducted out. Results. Oil content in seeds of oil radish (Raphanus var. oleifera sativus L.) was determined. The highest oil content was indicated for variety Kyyanochka – 42 %. Basing on chromatographic analysis of fatty acids of oil radish genotypes most optimal fatty acid composition for biodiesel production was identified in Kyyanochka variety due to high content of short-chained and monounsaturated fatty acids and highest oleic (18:1) acid content – 37.89 %. Conclusions. Taking in account results of chromatographic analysis and agronomic productivity the best genotype for biodiesel production were identified: variety Kyyanochka. Chosen genotype could be used for production of light types of biofuel which have potential to be used as additive for aviation fuel according to the optimal fatty acid composition Keywords: Brassicaceae, oil radish, varieties, breeding forms, oil, fatty acids, biodiesel production.

The Us

Castor is an important oilseed crop and although its oil is inedible, it has multiple industrial and pharmaceutical applications. The entire US castor germplasm collection was previously screened for oil content and fatty acid composition, but its genetic diversity and population structure has not been determined. Based on the screening results of oil content, fatty acid composition, and country origins, 574 accessions were selected and genotyped with 22 polymorphic EST-SSR markers. The results from cluster analysis, population structure, and principal component analysis were consistent, and partitioned accessions into four subpopulations. Although there were certain levels of admixtures among groups, these clusters and subpopulations aligned with geographic origins. Both divergent and redundant accessions were identified in this study. The US castor germplasm collection encompasses a moderately high level of genetic diversity (pairwise dissimilarity coefficient = 0.53). The results obtained here will be useful for choosing accessions as parents to make crosses in breeding programs and prioritizing accessions for regeneration to improve germplasm management. A subset of 230 accessions was selected and will be planted in the field for establishing a core collection of the US castor germplasm. Further evaluation of the US castor germplasm collection is also discussed.

Wild Peanut

Wild peanut species are useful genetic resources for improving the levels of disease/pest resistance and for enhancing the quality of seed composition by interspecific hybridization. The variation in oil content and fatty acid composition of wild peanut species in the United States Department of Agriculture germplasm collection is unknown. Seeds available from 39 wild species (plus a cultivated peanut) were requested from the U.S. peanut germplasm collection. Oil content was measured using nuclear magnetic resonance, fatty acid composition was analysed using gas chromatography, and the D150N functional mutation of theFAD2Agene was screened by real-time PCR. Significant variability in oil content (41.7–61.3%) was identified among the wild peanut species.Arachis magnacontained significantly more oil (61%) than cultivated peanut (56%). There was no functional mutation identified within theFAD2Agene target, and no wild species were identified with a high ratio of oleic acid to linoleic acid. The results from gas chromatography and real-time PCR analyses were consistent. However,Arachis sylvestriscontained a significantly higher amount (22%) of long-chain fatty acid (LCFA) than the cultivated peanut (4%). Thus,A.magnaandA. sylvestrismay be good breeding materials to use for increasing oil content or LCFA composition of cultivated peanuts in breeding programs.

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.

The results of long-term studies of the biological, morphological and phenological features of the introduced new culture of safflower in the Central, Volga and North Caucasus regions are presented. Optimum parameters of depth of seeding (5-6 cm), seeding rates (300-350 thousand pieces/hectare or 12-14 kg), ensuring high productivity, oil content and quality of seeds are established. For the first time, the relationship between moisture availability of vegetation periods with accumulation of oil content and a change in the fatty acid composition was established. Oilseed (in untreated seeds) in the regions was from 14,5 to 31,2%, in excessively wet 2013 – 6,4% in the Moscow region and 8,6% in the Saratov region. Fatty acid composition revealed a high content of oleic acid in Krasa Stupinskaya variety – 13,6-16,8%, linoleic acid – 68,5-75,7%. The yield of oil in the Moscow region was 240 kg/ha. The yield of Krasa Stupinskaya in the Moscow Region was 0,6 t/ha, the Rostov Region 0,8 t/ha and Saratov Region 1,2 t/ha, with an average weight of 1000 seeds, respectively, by regions: 40,0 g, 47,3 g and 40,9 g. The growing season for growing seeds was 105 days in the Moscow Region, 94 days in the Rostov Region and 95 days in the Saratov Region. It has been established that excessive moistening during the flowering and seed filling period increases the harmfulness of enzyme-mycosis seed depletion (EMIS) – biological injury during maturation (enzymatic stage), followed by the seeding of the seeds with the phytopathogen Alternaria carthami Chowdhury. In the breeding programs for productivity and oil content, it is recommended to use the varieties Moldir (Kazakhstan) and Krasa Stupinskaya (FGBNU VSTISP), the fatty acid composition of which is characterized by an increased content of oleic and linoleic acid, which is of particular value for storage and use for food purposes.

Dry Matter Accumulation

Self-pollinated seed from normal and erucic acid free plants of summer rapeseed (Brassica napus L.) was harvested at weekly intervals from pollination to maturity. Oven-dried whole seeds and their component parts were weighed and analyzed for oil content and fatty acid composition. Oil and dry matter accumulation followed sigmoidal patterns, most of the deposition occurring between 14 and 35 days after pollination (DAP). The relative contribution of the testa, endosperm and embryo to dry weight and oil content of whole seeds changed significantly during seed development. Oil content of the developing embryo varied from 22 to 44%, and the testa from 1.6 to 13%, although at maturity only 6 to 8% oil was found in the testa and adhering aleurone. The nucleate endosperm oil content was estimated to be low and in the order of 2 to 2.5%. In 7- to 14-day-old seeds the dry weight, oil content and fatty acid composition were largely determined by the testa and endosperm. From 14 to 21 DAP the testa and embryo were dominant and after 21 DAP the embryo was the controlling influence on the seed characteristics studied.Oils of the testa, nucleate endosperm and embryo differed in fatty acid composition. In seeds free of erucic acid, the ratios of the 18 carbon fatty acids of the embryo and testa remained nearly constant from 21 DAP to maturity. This suggested that the variation in fatty acid composition as well as oil content during seed development in this material was due to disproportionate changes in the contribution of the testa, nucleate endosperm and embryo. However, in developing seeds capable of producing erucic acid a change in the ratio of fatty acid synthesis occurred in both the testa and embryo.
