Л. А. Герасименко
Наведено результати досліджень впливу строків сівби та глибини загортання насіння на фотосинтетичну продуктивність посівів сорго цукрового сорту Силосне 42 в умовах центральної частини Лісостепу України. Зокрема, наведено дані стосовно площі асиміляційної поверхні листків рослин, фотосинтетичного потенціалу, чистої продуктивності фотосинтезу, а також дані двофакторного дисперсійного аналізу. Встановлено, що у разі сівби сорго цукрового в другій декаді травня (третій строк сівби) на глибину загортання насіння 4–6 см рослини розвивались краще, і за цих умов отримано максимальні значення показників фотосинтетичної продуктивності порівняно з іншими варіантами досліджень. Тому ми рекомендуємо третій строк сівби та глибину загортання насіння 4–6 см для вирощування цієї культури в зазначеній зоні

В. М. Стригун
The results obtained during observations of the growing season of pea collection varieties in different years in terms of interphase periods are presented. The dependence of the growing season length for varieties of various maturity groups on the duration of certain phases of plant growth (seedling, flowering, ripening), ambient environment (temperature, humidity, daylight hours), processing (seed preparation, line production maintenance) and genetic factors (sequential node of the first inflorescence formation) are shown. According to the study results the varieties-sources of «growing season length» characteristic were specified that have been used as components for breeding in the selection process when creating new domestic varieties.

Elements of energy-saving technology of table beet seed production (variety type of Bordeau) in the Eastern Forest-Steppe of Ukraine were improved, they include method of irrigation (drip irrigation, HB 70–65%), fertilizing (locally N 15 P 30 K 60 + N 15 ), fertigation (stage of 3–4 true leaves, bundle ripeness, the beginning of stooling and flowering), the use of standard mother roots 61–100 mm in diameter along with mother rootsstecklings 41–60 mm in diameter that increase average yields according to the size up to 1,89 t/ha. It is found that the application of micronutrient mixture of Zn + B + Mo in one term and mixture of Zn + B in two terms was the most effective.

В. М. Тищенко | М. В. Томіна | М. В. Дубенець
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.

Assessment of agroclimatic conditions in 2012–2014 and their effect on formation of frost resistance and winter hardiness of soft winter wheat is made. Elevated temperature conditions in autumn and disturbance of cold hardening conditions caused the formation of the highest frost tolerance and winter hardiness of winter wheat only up to -15°C. Under the new climatic conditions the modern varieties of myronivska breeding are able to realize 80–85% of the genetic potential by the property.

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.

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

Abstract Draft genomes of the fungal species Fusarium xylarioides, Teratosphaeria gauchensis and T. zuluensis are presented. In addition an annotation of the genome of Ceratocystis fimbriata is presented. Overall these genomes provide a valuable resource for understanding the molecular processes underlying pathogenicity and potential management strategies of these economically important fungi.
