Abstract:

Interest in oil flax has been growing in recent decades. Linseed oil is a fast-drying oil and it is traditionally used in the production of linoleum, paints and coatings. Due to their content of essential polyunsaturated acids and vitamins, the growing use of flax seeds and oils in food and medicine has significantly increased the volume of its cultivation in different countries. This article presents the main research results for 2018−2020 of a large group of varieties of oil flax of Zaporizhzhia breeding for economically valuable traits. The purpose of research is to establish the genotypes that form the highest yields and oil content in arid conditions of the Steppe zone of Ukraine. It was found that the most productive year was 2020 due to more favorable temperatures and even distribution of precipitation during the growing season of oil flax. It was found that the yield of oil flax had a high correlation coefficient with weather conditions (r = 0.67) especially from precipitation in May-June (r = 0.60). A detailed study of the correlation between yield and habit traits and the main economically valuable traits revealed a close direct correlation between oil flax yield and seed weight per 1 plant (r = 0.99), yield and number of lateral stems per plant (r = 0.93), yield and number of bolls and seeds per 1 plant (r = 0.77), yield and weight of 1,000 seeds (r = 0.73), yield and duration of the growing season (r = 0.65). According to the results of three-year research, the highest yield was obtained from the variety Vodohrai 1.79 t ha-1. The highest oil content and oil yield per hectare were formed by varieties Vodohrai 50.1% and 0.80 t ha-1, Zolotystyi 49.7% and 0.76 t ha-1, Aisberh 48.3% and 0.72 t ha-1.

Abstract:

Studies to assess the breeding samples of soft winter wheat by weight of grain from the main ear and determine the indicators of adaptability were conducted at the Bila Tserkva Research and Selection Station (BTRSS) in 2011–2013. The study revealed significant differences in breeding lines in the range of variability of grain mass from the main ear and identified small, medium and significant coefficients of variation, which indicates their excellent response to environmental conditions. It was due to genotype, year conditions and their interaction. Line 42 KS had significantly higher than the standard grain weight of the main ear (0.14 g) and the lowest value of the coefficient of variation (8.7%). According to the indicators of adaptability (GAC, σ²(GxE)gi, σ²SACi, σSACi, etc.) the lines 42 KS, 24 KS and 44 KS were distinguished. There was a significant correlation between the weight of grain from the ear and the weight of 1,000 grains (0.603–0.674) and the direct influence of the weight of grain from the main ear on the weight of grain from the plant and grain yield (0.805–0.942). Selected lines as a result of research (2015–2020) from these populations of soft winter wheat are competitively tested in the conditions of Bila Tserkva Research and Selection Station, forming high grain yields (7.39–8.12 t ha-1) and will be transferred to 2021 for the State variety test for inclusion in the Register of plant varieties suitable for distribution in Ukraine.

Abstract:

The study of the physical and consumption qualitative indices of the highbush blueberries (the cultivars ‘Reca’, ‘Elizabeth’ and ‘Bluegold’) in the Western Lisosteppe of Ukraine has shown that the biggest fruit mass was accumulated by the berries of two last mentioned vs (1.54–1.50 g respectively). ‘Bluegold’ has this indicator as the least variable (V = 10.6%). The accumulation of fruit mass of all studied cultivars was facilitated by a moderately humid period of their development in 2018 with a hydrothermal coefficient of 1.1–1.2. The favorable year for the intensive synthesis of the dry matter and soluble solids was 2017 when the precipitation amount did not exceed 44 mm. The biggest number of the mentioned substances during the research period was accumulated by fruits of ‘Reca’ – 17.48 and 13.24%, respectively. It was established that the dry matter content had high level of stability (V = 8.2%), and middle was for soluble solids (V = 19.5%). The amount of monosaccharides from which glucose and fructose were investigated in fruits varied from 6.11 (‘Bluegold’) to 7.85 (‘Reca’), it was slightly lower in ‘Elizabeth’ berries – 7.78%. ‘Bluegold’ fruits were characterized by high stability (B = 9.6%) of the biggest content of titrated acids among the studied cultivars (2.42%). The dry weather with low number of precipitation in 2017 (hydrothermal coefficient 0.3–0.4) was favourable for the accumulation of both the mentioned acids and vitamin C in fruits of highbush blueberries in the period of their formation and growth. The amount of ascorbic acid in fruits in the specified year varied from 20.00 mg 100 g-1 WM (‘Reca’) to 27.00 mg 100 g-1 WM (‘Elizabeth’) with an intermediate value of 22.50 mg 100 g-1 WM (‘Bluegold’). The latest of the mentioned varieties had the most constant index (V = 7.0%). The content of polyphenolic substances was slightly dependent on weather conditions during the period of fruit growth, the coefficients of variation were 6.2% (‘Reca’), 7.0% (‘Elizabeth’) and 5.8% (‘Bluegold’). The fruits of the last mentioned cultivars were characterized with the biggest anthocyanins and chalcones content (68 and 13 mg 100 g-1 WM, respectively). The substantial indirect dependence of the content of the nutritive substances and anthocyanins on the berry mass was revealed in the ‘Reca’ fruits.

Abstract:

In this study, a lentil variety, Idlib-3, was subjected to 100 Gy (LD50) gamma-ray irradiation. At M2, mutant families were characterized for the most beneficial agronomic traits. High genotypic coefficient of variation, broad sense heritability and genetic advance of the traits such as seed yield per plant and hundred-seed weight indicated expression of additive gene action and confirmed the response at early generation selection. Total number of pods per plant had positive correlation and the highest positive direct effect on seed yield per plant and hence the preference should be given for this trait during selection. The novel mutant families identified with early flowering, early maturity (families 5 and 90) in cluster I, and more first pod height (families 10, 70 and 82) in cluster II could be utilized to breed short duration lentil varieties suitable for machine harvest.
