2013
Козенко, А. О | Дроща, П. В | Данюк, Т. А
The article analyzes range of problems related to the erection and development of vertical financial equalizing on the background of processes that have triggered after Ukraine acquired its sovereignty. The basic stages and trends of the development are detected for the vertical financial equalizing in Ukraine, which essentially corresponded to the changes in arrangement of inter-budget relations. It is proved that the currently available trends in the development of inter-budget relations in Ukraine have been associated with the stages of vertical financial equalizing in Ukraine. The current system for financial vertical equalization in Ukraine is self-contradictory and slows down social and economical development of the country. Taking this into account the proposals were established as regards the main approaches to further reforming of the system of vertical financial equalization in Ukraine in terms of its shifting to the market economy, setting budget laws of the country in conformity to the legislation on the structure of executive power and local governments, as well as other acts of law determining their functions.

2013
Кутовенко, В. Б | Гаврилюк, Н. С
The article highlights potential features for the varieties of vegetable bean and actual losses of yield subject to the total amount of photosynthetically active radiation (PAR) received over the vegetation period in the Forest-Steppe of Ukraine. It is established that the potential of the vegetable bean yield in Ukraine depends on PAR received over the vegetation period. All the varieties had their yield upon receiving PAR higher by 0,26-0,41 t / ha compared to that of control. Potential yield of vegetable bean varieties when PAR is used by 2% amounted to 57.25–59.30 t / ha, which was 2.2–3.6 times more than their actual yield. The smallest actual yield loss compared to that potential was inherent in the varieties of Bartoli and Windsor (2.2–2.3 times). The actual yield losses for Karadag and Karestyno varieties were the highest, namely 3.6 times higher compared to the potential prospect.

2013
Ящук, Н. О
Influence of varietal characteristics and growth factors on the quality of Natsional’na and Polis’ka 90 winter wheat varieties was studded. Grain of Polis’ka 90 variety was distinguished by considerable variability of grades, however, the grain of Natsional’na variety was exposed to greater number of growth factors. Grain unit index influenced the grain quality grade of Natsional’na 90 determination, gluten quality and protein and fiber content indices influenced that of Polis’ka 90. It was established that the grain of Polis’ka variety in most of the cases had higher grades of quality than Natsional’na variety. The highest grades of quality were registered for the seed harvested after perennial grasses, namely 2d and 3d grades of Natsional’na variety and the 1t and the 2d for Polis’ka 90 variety. Greater grades of quality were registered for the seed grown according to intensive and ecological farming systems (generally, grades 1 to 3), while the lower grades were inherent to biological system (generally, grades 3 to 5).

2013
Долматов, Є. О | Джафарова, В. Є
The article highlights results of research over simulative apomixes in pear and its utilization for obtaining haploids and homozygote diploids. It has been established that over 50% pear varieties with failed remote hybridization are capable of generating seeds of apomictic origin producing diploid plants. Genotypes displaying maximal inclination to apomixes have been singled out. Apomictic pear seedlings obtained from foreign pollination within the limits of the same combination are inherent in profound morphological diversity. Fruit-bearing apomicts originated from one and the same maternal plant differ to the same extent as hybrid seedlings of the same family. Genetic markers have enabled to establish that these are embryo sacs in which meiosis has completed that give rise to apomictic seeds. In vitro method as used for the purpose of increasing apomictic plants output has been illustrated. The greatest induction of apomictic shoots in vitro has been reached by alternation of BAP cytokinin at concentration of 1mg/l and 2 mg/l on the background of GA3 amounting to 1,5 mg/l. Grafting with shoots in vitro on non-sterile rootstocks of pear (Pyrus communis) has increased the output of plants up to 80%. A cytological assessment of 9 apomictic samples is provided. The cytological analysis of samples of apomictic forms has certified the presence of simulative haploid parthenogenesis in pear.

2013
Скорик, В. В
A stabilizing (directed) selection has created a donor of short stem for winter rye (Secale cereale L.), plant height of which ranged from 50 to 60 cm. The plant height kept symmetry of its distribution curve and the frequency accumulation in central classes (positive excess). For the first time a symbolic designation to new short-stem related Hl-2Hl-2 allele and the donor name (Gnome 2) were proposed. 28 years of stabilizing selection showed that 57% of overall genetic variability of plant height resulted from adaptive genes available for directed selection by phenotype, and 43% from dominant and epistatic factors that predetermines the expression heterosis effect. Gnome 2 donor proved to have genetic additive correlation between the pants height and number of flows per ear, ear length, weight of seeds per plant , 100 seeds weight per plant; to have reverse correlation with ear density seeds weight per ear. The height of original parent components have displayed direct additive correlation with number of flowers per ear and reverse with the ear density. The additive correlation component directly exposes «genuine» impact of parental plants on the expression of the characteristics indicated among the offspring Productive bushing of parental plants, seed weight per plant directly, and seed size (100 seeds weight) indirectly, respectively, influence the height of offspring pants. The reverse additive correlation between the parents height and 100 seeds weight in the offspring is caused by pleiotropic effect of the genes impact thus enabling to combine the desirable characteristics in one genotype. Productive bushing is by 54% due to the impact of general genetic factors among the above, in particular, 30% due to that additive, 24 due to non-additive factors. The concept of genetic improvements for productive bushing of the Gnome 2 rye implies utilization of additive effect through the directed selection, as well as application of breeding techniques for controlling the effect of heterosis caused by the genes of dominant and epistatic impact. The selection paradigm requires simultaneous genotypes selection with immediate examination of the selection results by offspring while in parallel to develop inbred lines, combining these afterwards evaluating general and specific combining ability by productive bushing. It is also to be noted that the productive bushing essentially depends on the environmental conditions, which significantly corrects the implementation of productivity potent, thereby the issue of agronomical conditions aimed at extending the expression of characteristic in question remains.

2013
Галашева, А. М | Красова, Н. Г | Янчук, Т. В
In connection to the climate changing and draught frequency increasing in the spring-summer period the fractional composition of water (combined and uncombined water) in leaves of apple from May to August 2011, 2012 were studies. Combined and uncombined waters have different functionality for the life of plants. An uncombined water in leaves determines intensity of physiologic processes while the combined is responsible for plants resistance to unfavorable conditions. The fractional composition of water was studied in apple leaves of varieties bred by All-Russian Research Institute for Fruit Crop Breeding of RAAS, Bolotovskoye, Irmus, Orlik, Orlovim, Orlovskoye Polosatoye, Sinap Orlovskiy, Yubiliar in comparision to widespread varieties – Antonovka, Melba and Welsi. The study established that the varieties examined were well-adapted to drought in May, at the beginning of summer, as well as at the end of August and in September. At the beginning of July and in June higher indices of drought resistance were registered for Orlovim and Yubiliar, with the highest indices of combined water content. The completion of shoots growth and development of leaves system in all apple varieties was associated with increase of combined water amount in the leaves in August. In September, the number of combined water remained higher that suggested high adaptivity of the varieties being studied. The highest content of combined water in autumn was registered for Sinap Orlovskiy, Antonovka, Boltovskoie, Irmus.
