ABSTRACT Peanut varieties with high oleic/linoleic acid ratios have become preferred by the peanut industry due to their increased shelf life and improved health benefits. Many peanut breeding programs are trying to incorporate the high oleic trait into new and improved varieties and are in need of diagnostic tools to track its inheritance early in development and at the single seed level. Traditionally, gas chromatography has been used to accurately determine the properties of peanut oil. Recently a method was developed to carry out this analysis by capillary elecrophoresis providing researchers with an alternative analytical platform. In this study, the use of capillary electrophoresis and gas chromatography for analysis of oleic/linoleic acid ratios are compared. Oil was extracted from approximately 0.10 g of peanut seed tissue taken from the distal end, leaving the embryonic end of the seed intact for subsequent germination. Over 100 samples inclusive of runner, Spanish and Virginia market types were processed. Oil extracts were analyzed for oleic/linoleic acid ratio using (1) capillary electrophoresis (CE) and (2) gas chromatography (GC). Results showed that the two methods are 100% in agreement in determining whether a peanut seed is “high-oleic” or “normal oleic” in oil content. Furthermore, the two methods are highly correlated (r  =  0.96; p < 0.0001) with respect to determining the exact oleic/linoleic acid ratio from each sample. Results from this study validate the use of CE as a diagnostic tool for breeding programs to identify individual high oleic peanut seed for further testing and development.

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.

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 article offers studies to identify the effectiveness of chemical preparations for desiccation in spring wheat crops. The research was conducted in 2017-2020 in the conditions of the Ryazan region. It was revealed that in the phase of the yellow-green pod, the organs of the surepitsa plants were characterized by different humidity. The stems (up to 75%), the leaves of the pods (about 55%) and the seeds (40%) had the maximum humidity. On average, according to the experience, a high increase in seeds was observed on the variant with sowing in the first decade of May, Dikoshans, BP, 3 l/ha – 20.0 c/ha (+11.7% to the control or +2.1 c/ha). The average maximum yield in the second sowing period was noted on the Glyphoshans, BP, 3 l/ha variant-18.4 c / ha (+1.5 c/ha or +8.8% to the control) and on the Dikoshans, BP, 3 l/ha variant-18.3 c/ha (+1.4 c / ha or + 8.2% to the control), which proves the high efficiency of using the desiccation method in the production technology of spring surepitsa oilseeds.

Commercial Harvesting

Soybeans IAC-8 were harvested in the growth stages R7 and R8 commercial harvesting time and at two other subsequent times to compare their physiological and technological characteristics. Seeds were stored at two moisture levels, 12% and 15%, for 6 months. Germination and vigor (acelerated aging, electrical conductivity), oil and free fatty acids, peroxide and iodine values were evaluated periodically. As expected, the time of harvesting and seed moisture content affected seed performance, while oil content did not correlate to physiological quality as did acidity, peroxide value and iodine number.

The Relationship

Seed moisture content is a well-recognised index of safe storage. However, when in equilibrium with the storage environment it is merely an indicator of the relative humidity of the air, which is the primary regulator of the growth of moulds and insects. The relationship is influenced by the profile of the seed components. During the 1990s, significant increases in the seed oil content of evening primrose were achieved through plant breeding. This paper shows that the equilibrium moisture content of evening primrose seeds declines significantly with increasing oil content. Hence, the moisture isotherm is altered and newer cultivars must be stored at slightly lower seed moisture contents to ensure that seed and oil quality are maintained.

Several sunflower cultivars were seeded at approximately weekly intervals from early May to 20 June from 1978 to 1981. In another experiment the plots were harvested at different dates to study the effects on yield and oil quality. In general the yield was highest for all cultivars at the earliest seeding, with the late maturing cultivars performing the best. In late plantings, the yields were in general lower and early maturing cultivars performed better than the later ones. The cross-over point varied from year to year ranging from 16 May to 7 June except in 1981 when there was no cross-over. The oil content was similarly affected, declining more rapidly with delay in seeding in the later maturing hybrids than in the early hybrids. In the separate study on harvest dates, maximum oil content was reached when seed moisture content had declined to 45%. This occurred approximately 1 wk earlier in the early cultivars than in the late ones. Maximum linoleic acid level was reached approximately a week after the maximum oil content was obtained.Key words: Seeding date, sunflower, oil content, yield, linoleic acid, harvesting date
