Effect of sowing time on the realization of productivity potential of modern varieties of soft winter wheat in the context of climate change النص الكامل

The effect of sowing time on realization of the natural productivity potential of modern soft winter wheat varieties was studied. It is established that the use of current agricultural technologies in a context of climate change has caused shift of calendar sowing terms to the second half of the optimal terms comparing with earlier cultivated varieties. In subzones of Kirovohrad and Bila Tserkva state variety testing stations the highest yield of winter wheat is formed in case of sowing on September 20–30, but the optimum for Kirovohrad station fall on September 30, Bila Tserkva station – on September 20 and 30. Sowing in earlier or later time leads to decreasing yields, especially of Vynnychanka, Smuhlyanka, Zolotokolosa and Tripilska varieties. Bogdana and Kuialnyk varieties are the most adaptive to sowing time under agroecological conditions of Kirovohrad state variety testing station.

Проведено аналіз урожайності та її структури у 15 ліній конкурсного випробування пшениці озимої м’якої в умовах Північного Степу України. Виявлено перспективні продуктивніші лінії порівняно зі стандартом. Досліджено особливості формування врожаю залежно від генотипу, кліматичних умов і впливу деяких кількісних ознак. Встановлено, що вища продуктивність формується у разі підвищення таких показників, як кількість зерна з колосу, маса 1000 зерен. Рекомендовано для використання нову високопродуктивну лінію 92-946, що переважає стандарт в середньому на 0,56 т/га.

Assumption is made that identification of valuable genotypes is possible in specific stability points of phase-parametric systems, that is, when the effect of dynamism acquires gradient and discrete anisotropic composition by way of converting the phenotype variability in the temporal and parametric and characteristic specific vector-spaced system. Devices have been suggested (electronic board for the characteristics spectral expression, 3D configuration of a characteristic variation series) for displaying the location sample parametric pool in the general statistic range of quantitative characteristics. A characteristic has been detected (number of seeds in a pod) that carry the traits inherent in pseudo-qualitative and oligogenic characteristic. According to findings of the study, characteristics are identified that conform to various directions of economical use

The main factor, and cost-effective rapid increase in yield of all crops and raising its quality is an innovative process for the creation and introduction of new varieties. Overall condition of use in the production of new varieties is very unsatisfactory. For this year the country loses more than 1.5 mln. tonnes of grains of winter cereals. Currently, the requirements for soft winter wheat, as a factor of sustainable productivity, increase. Despite the obvious advances in breeding wheat varieties as genetic yield potential of more than 10 t/ha, the actual implementation of it is around 50 %. Therefore remains an urgent problem of developing varieties with high potential and implementation of evidence-based their growth. Thus, the genetic yield potential genotype implemented with a balanced exposure of a number of factors. The purpose of research – create a soft winter wheat variety with well-defined ecological and adaptive properties and high quantitative and qualitative indicators of grain yield, varieties show ability to withstand adverse abiotic, biotic and anthropogenic factors of the environment for future breeding. Stated agroecological characteristics of variety soft winter wheat Yuvivata 60 by economically valuable indicators. Performed a detailed description of the new variety wheat based on morphological and biological characteristics. Showing environmental features Yuvivata 60 (in terms of genotypic effect and degree of plasticity) under different conditions ecotops of Ukraine. For agricultural producers proposed of adaptive variety soft winter wheat Yuvivata 60, that will provide guaranteed high quality and grain yield.

The article presents the results of the laboratory investigation of the influence of high temperatures on water regime of red currant in Institute of Fruit Selection. It shows the dependence of water loss by leaves on the phenophase of plant development. High water loss by leaves occurs during the phase of ripening berries (July). Low water loss is noted during the active growth of shoots (June). Red currant genotypes: «Valentinovka», «Bayna» have a high percent of water loss in June and July. Genotypes «Shedraya», «Gollandskay krasnay», «Orlovchanka», «Dar Orla», «Selyanochka», «Osipovskay», «Belka» and «Jonker van Tets» have a low percent of loss water. The loss of water at the temperature shock is the important protective mechanism from over heat and death of plants. The results of the investigation of a degree of water restoration by red currant leaves in the periods of berry ripening and active growth of shoots are given. The most part of genotypes of red currant leaves have a high percent (>50%) of water restoration. Genotypes «Selyanochka» ,«Orlovchanka», «Dana», «Shedraya», «Belka» have a more 100% of water restoration. On the ground of the obtained results the following genotypes: «Belka», «Selyanochka», «Gollandskay krasnay», «Shedraya», «Orlovchanka», «Dar Orla», «Osipovskay» and «Jonker van Tets» are mostly heat resistant.

Purpose. To study effects of low temperatures on Lavandula angustifolia plants and their response depending on their age and variety as well as identify critical temperature values for such structure elements of plants as bark, cambium, wood, pith. Methods. Field investigation, spectrometric analysis, statistical evaluation. Results. Topicality of investigation of Lavandula angustifolia to be grown in the Forest-Steppe zone of Ukraine was highlighted. Low temperature effects on structural elements of shoots for 8 varieties of domestic and foreign selection were analyzed. One-year shoots have suffered the most from low temperatures – 4.5 points on a six-point scale, two- and three-year shoots were damaged in a lesser degree – from 0.8 to 2 points. Plants of ‘Feuervogel’ and ‘Maestro’ varieties with total damage coefficient of 11.3% and 10.6% accordingly were the most resistant to low temperatures. These varieties can be recommended to producers for further introduction to the Forest-Steppe zone of Ukraine. Conclusions. Tissues of a lavender one-year shoot were most damaged by low temperatures regardless of a variety, but this organ is ephemeral and can be removed without causing damage to a plant. Two- and three-year shoots, which provide plant recovery, were significantly less damaged. None of the plants from 8 studied lavender varieties was lost under the influence of low temperatures, though some of them were damaged significantly. Such varieties as ‘Feuervogel’, ‘König Humbert’, ‘Veseli notky’ (pith damage is on the level of 1–2 points), ‘Maestro’ (0.8–2.5 points) were the most resistant to low temperature exposure which allows to conclude about successful lavender cultivation under conditions of the Forest-Steppe zone of Ukraine.

The paper highlights results of 60 years of apple breeding activity at the All-Russian Research Institute for Fruit Crop Breeding of RAAS (former Orel Zonal Fruit-Berry Experimental Station). Major selection effort has been applied to apple breeding for higher contents of ascorbic acid and P-active substances in fruit. A pattern of the inheritance of biologically active substances in apple fruits is shown. First time in Russia a large-scale selection has taken place for the purpose of developing domestic scab immune apple varieties (Vf). 20 scab immune varieties have been created and included into the State Register. First time in Russia and in the world a range of triploid apple varieties have been developed through directed diverse chromosome crossings 2x x 4x and 4x x 2x.
