Assessment of new self-fertile breeding samples of lucerne (Medicago sativa L.)
2014
Н. В. Башкірова | А. О. Глибовець
Yield of modern varieties of valuable fodder crop lucerne is quite low - 0.2 - 0.3 t / ha. The reason - lack of cross-pollination due to the lack of insect pollinators. Under these conditions, the highest seed production plants are prone to selfpollinate. The results of the study of 26 new selffertile samples of alfalfa own selection. It was shown that 15 samples for seed yield higher than standard - grade Jaroslavna. The herbage yield of only four samples was lower than in the standard. The dry matter content of all samples was high - 22,1-25,5 %. The results obtained are allowed to select in hotbed of pre-strain testing samples with high levels of self-fertility, seed yield 0,24-0,29 t/ha, herbage for three mowing - 63,2-67,7 t/ha, high dry matters content, which will be used in future breeding process

The article presents results of characteristics studying for generative and vegetative parts of soft winter wheat in the conditions of autumn moisture shortage and in the conditions of optimal moisture supply. During the period of studies a dramatic difference of the levels of generative and vegetative parts of plants has been observed. As a decreased level of characteristics development has been noted, so its increasing, in particular, among the varieties of generative part. within 7.2% (thousand seed weight) to 42.6% (seed weight per ear). It is found that efficient development of generative organs is subject to variety bushing capacity, in particular at spring. The article also shows that stress conditions of autumn period influence late emergence of seedlings; however, that goes along increased level of some characteristics development at generative part. Obviously, during such years the selection of breeding material as per ear yield would not be efficient. The article, for the purpose of excluding negative consequences of selection, pays special attention to such characteristics as that not affected by stress environmental conditions. This indicates genetic stability of those characteristics, so their use as marker characteristics in yield specific breeding is advised.

О. В. Панфилова | З. Є. Ожерельєва | О. Д. Голяєва
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.

В. В. Москалець | Т. З. Москалець | В. І. Москалець | Н. М. Буняк
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.

This paper presents the results of molecular studies on testing and evaluation of multiplex test systems for the genetically modified organisms’ (GMOs) identification by PCR in real time. For the detection of genetic modifications in plants of the cabbage family (Brassicaceae) screening of major regulatory sequences is insufficient, as in genetic engineering manipulations 35S promoter – of DNA-containing cauliflower mosaic virus (CaMV) is used, which presence in the test material can lead to false positive results. In this work the feasibility of testing for the presence of viral CaMV’s DNA and analysis of screened gene sequences of interest for the usage during the analysis of rapeseed (Brassica napus L.) samples. It was established that the analysis of the presence/absence of a positive result for the CaMV 35S promoter is not giving complete answers to the absence of GMO in the sample. The appropriateness of GMO’s screening in rape seeds with NOS terminator and genes of interest.

2014
Л. І. Перевертун | А. М. Проданик | С. О. Ткачик
Race-specific resistance of 19 common millet varieties that are firstly listed on the State Register of Plant Varieties Suitable for Dissemination in Ukraine in 2013 is assessed. It is found that almost half of the varieties are infected with all smut races, part of them is resistant only to the first group of smut races, and there is no variety to be resistant to all races of this disease. It is concluded that common millet varieties are needed to be examined for resistance to smut races

2014
К. П. Тарнавська
New results of the clonal selection of apple tree (Malus domestica Borkh) conducted at Podillya Research Station of Horticultural Institute NAAS by method of state variety testing have been presented. By the results of the 6-year studying (2007 - 2012) of 20 new Jonagold clones of domestic selection their estimation was carried out according to the complex of such qualities as productivity, early ripening, marketability, taste qualities and durability of fruits. The following clones are defined to be the best: DP-16, DP-17, DP-18, DP-20. They start fruiting in the age of 2 or 3 years, productivity of the 5- or 6-year-old trees reaches 8,3–25,5 tons per hectare, quantity of the fruits of the highest and first grade is about 57–76% (in 2010–2012). Fruits of the mentioned clones are bigger than medium size (DP-16), big (DP-17, DP-18) and very big (DP-20); they have average similarity, excellent and very harmonious sour-sweet taste (8,3–8,7 points). Fruits of the best clones kept their quality for 202 – 220 days.
