Middle content of oleic acid in high oleic lines of winter rapeseed in hot 2019 was maximal and equal to 81.2 %, and minimal one – in a cool 2017 – 75.3 %. Studying of influence of day and night air temperatures in a period of seed formation (19.0–32.4/10.6–24.0 °С) on oil and glucosinolate contents in seeds of high oleic winter rapeseed did not demonstrated any significant dependences between these traits. There were not observed any important relations between amount of precipitations in a period of seed formation and oil content, fatty-acid composition of oil and glucosinolatec content in high oleic winter rapeseed.

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.

Aim. Main aim of this research was a comparison of fatty acid composition for seed oils from of turnip rape breeding forms and varieties produced in M.M. Gryshko 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 mentioned above turnip rape genotypes were conducted out. Results. Oil content in seeds of spring (Brassica campestris f. annua D.C.) and winter (B. campestris f. biennis D.C.) turnip rape forms and varieties was determined. The highest oil content was indicated for winter variety Oriana – 38.1 %. Basing on chromatographic analysis indicated two types of fatty acid composition: high-erucic with content of 22:1 fatty acid up to 42.8 % and high-oleic with content of 18:1 fatty acid up to 46.92 %. Conclusions. Taking in account results of chromatographic analysis and agronomic productivity the best genotypes for biodiesel production were identified: winter variety Oriana and spring form EOSYaF-1. Chosen genotypes could be used for production of two different types of this biofuel – “light” and “heavy”, – according to difference in fatty acid composition.Keywords: Brassicaceae, turnip rape, spring varieties, winter vatieties, oil, fatty acids, composition, biodiesel.

The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified two novel mutant alleles: one for each gene that is responsible for the elevated oleic acid content in four plant introductions. The combination of the newly identified mutant FAD2-1B allele with existing or the novel mutant FAD2-1A alleles created soybean lines with more than 80% oleic acid content. Combination of two mutant FAD2-1A and FAD2-1B with mutant FAD3A or mutant FAD3C or both resulted in high oleic acid content of 80 - 85% and linolenic acid content in the range from 1.5 - 4%. Perfect molecular markers associated with these mutant alleles were designed to help select the soybean lines with genotypes of interest in early generations in breeding. The high oleic acid and high oleic acid low linolenic soybeans produced have an improved stability across growing environments compared to existing sources.

Selection Of

Varieties and hybrids of agricultural crops are characterized by a large number of indicators: morphological, economically valuable, biochemical. Usually, when conducting a comparative analysis of selection samples at the initial stage of research, only a few traits are used, which are assessed using one-dimensional criteria. In research on rapeseed breeding, an integrated approach is also important in the assessment and selection of promising samples, taking into account the morphological characteristics that are components of productivity; oil content and quality, as well as the glucosinolate content of the seeds. Cluster analysis is a multivariate method for determining the optimal values of the estimated indicators. The aim of the research is the analysis and selection at the initial stage of research of promising breeding samples of winter rape, suitable for further work, using the "k-means" clustering method. The material of the research is 125 breeding samples of winter rapeseed. The number of pods on the central branch, the content of oil and glucosinolates in the seeds was determined, and the fatty acid composition of the oil was analyzed (the content of palmitic, stearic, oleic, linoleic, linolenic and erucic acids in it). The studies were carried out during 2018-2019. in the conditions of the southern Steppe of Ukraine. Statistical processing and evaluation of research results was carried out using a modified "k-means" clustering method, which is carried out using Data Mining. It differs from the classical clustering method in the selection of the optimal number of model clusters, which is performed by the Statistica software package. The processing and analysis of the material under study was carried out in two stages. At the first stage, using cluster analysis by the "k-means" method, separately for economically valuable traits and fatty acid composition of the oil, clusters of samples with the best ratio of the corresponding indicators were determined. At the second stage, the best samples from these clusters were selected only by the content of oil and oleic acid, and again by clustering the group of samples with the maximum value of these indicators was selected. From the cluster analysis for the fatty acid composition of the oil, the sign of the content of linoleic acid was excluded due to its high correlation with oleic acid, as well as erucic acid due to the discrepancy between its sample and the normal distribution. Reduction of samples to dimensionless form, preceding cluster analysis, is carried out by normalization on the z-scale. As a result of cluster analysis, we obtained the distribution of samples according to economically valuable characteristics into four clusters, and according to the fatty acid composition of oil into two clusters. The samples that form these clusters were also identified. The first cluster for economically valuable characteristics unites 26 samples, the second 33, the third 39 and the fourth 27. The first cluster for the fatty acid composition of the oil contains 72 samples, the second 53. The highest content of oil in the seeds and the number of pods on the central branch with the minimum content of glucosinolates in the seeds are inherent in the third cluster, and the maximum content of oleic acid in the oil - in the samples that form the second cluster. Analysis of variance of the clustering results showed that the average values of the economically valuable traits and the fatty acid composition of the oil in the clusters differ statistically significantly. Thus, clustering by the "k-means" method formed clusters of samples that statistically significantly differ from each other in the studied characteristics. Only 15 samples are simultaneously included in the third cluster, formed according to economically valuable characteristics, and in the second cluster according to the fatty acid composition of the oil. The second stage is the selection of the best samples from this group based on the oil content in the seeds and the oleic acid content in it for further breeding work. Based on the results of cluster analysis, a distribution into four clusters was obtained. Finally, for further selection studies in order to obtain a high content of oleic acid in the oil, five samples of the first cluster were selected (the content of oleic acid in the oil is 69.4-70.6%, the oil content is 49.0-52.1%). And also three samples combined into the second cluster with an oil content of 51.1-51.8%. Thus, the effectiveness of the application of the modified clustering method "k-means" for the analysis of a large number of samples of winter rapeseed for several characteristics simultaneously with the aim of selecting genotypes with an optimal ratio of economically valuable indicators has been proved.

Abstract Peanut (Arachis hypogaea L.) breeding lines with the high oleic fatty acid trait, acceptable yield, and acceptable grade have shelf-life quality characteristics that are much better than existing cultivars, however, the effects of this changed fatty acid composition on peanut sensory attributes are not known. Sensory evaluation of roasted-peanut paste from four high oleic acid breeding lines (F1250, F1315, F1316, F1334), Florunner, and NC 7 indicates that improvement in fatty acid composition of peanut lines does not appear to be associated with changes in roasted peanut attribute intensity. The breeding lines had similar attribute intensity to an accepted industry standard, Florunner, and were significantly better than NC 7 (4.4–4.8 vs. 3.9, respectively). F1316 and F1334 had higher (though not significantly higher) roasted peanut intensities than the other high oleic acid breeding lines (4.8 vs. 4.4–4.7, respectively). Comparisons for other sensory attributes, fruity, sweet, bitter, stale, painty, tongue/throat burn, astringent, woody/hulls/skins, and sour were not significantly different from Florunner or NC 7.

Diquat was applied at 0.3 kg (a.i.)/ha to sunflower (Helianthus annuus L.) at various stages of maturity in a 3-yr study to determine its effects on some agronomic and quality characteristics. The applications effectively hastened drying of the leaves and heads but stem drying was variable. Achene drying depended largely on the weather, with good advancement in some instances, but little advancement under cool, damp weather conditions. Advancement in harvest date by the treatments, taking into account both seed and plant drying, ranged from 0 to 26 days. Application made before physiological maturity reduced yield, oil content, 1000-achene weight, test weight and protein content of the meal. Fatty acid composition was also affected but to a lesser extent. There was no effect on achene germination. Applications made after the moisture content of the achenes had dropped below 45% did not appear to have any detrimental effects on achene yield or quality.Key words: Sunflower, desiccation, diquat
