Abstract In this study, the taxonomic diversity of the Xylodon raduloides species complex (Hymenochaetales, Basidiomycota) is examined. Specimens were studied using an integrative taxonomic approach that includes molecular phylogenetic and morphological analyses, and environmental niche comparisons. Four different species were found inside the Xylodon raduloides complex, with a biogeographic distribution pattern bound by geographic regions: Europe, North America, Patagonia, and Australia–New Zealand. Molecular, morphological, and environmental evidences delimit two lineages within this complex: a Northern Hemisphere clade with longer basidiospores and wider ranges in temperature and precipitation tolerance, and a Southern Hemisphere clade with smaller and more spherical basidiospores, and an isothermal and more humid climate preference. The integrative taxonomic approach used in this study demonstrates congruence between data sets and shows how morphological and environmental characteristics contribute to the differentiation of fungal species complexes. By combining various sources of taxonomic information, three new species are described: Xylodon laurentianus, X. novozelandicus, and X. patagonicus.

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.

The objective of the research is to improve the technology of growing high-quality seeds of millet broomcorn by means of the optimization of sowing terms and methods, aimed at increasing its productivity and improving seed qualities under conditions of unstable moistening of the Right-Bank Forest-Steppe of Ukraine. Scientific literature review indicates the study of the influence of these technology elements on the formation of sowing qualities and crop capacity of millet seeds has been of schematic and occasional nature. The issue has not been studied in this region condition at all, that is why the research has considerable significance and novelty. Analysis, observations and calculations were done by means of conventional methods. Research results indicate that under conditions of unstable moistening of the southern part of the Right-Bank Forest-Steppe of Ukraine the highest yield of Slobozhanske and Lana varieties was reached at sowing in drills – 39.2 and 41.0 metric centners per hectare, respectively. That was 2.4 and 3.9 metric centners per hectare increase against the wide-row sowing. In the years with optimal hydrothermal conditions maximum seed productivity of millet broomcorn at the level of 4.24 to 4.79 metric tons per hectare (Slobozhanske variety) and 4.53 to 5.28 metric tons per hectare (Lana variety) was observed at postponing the sowing terms to the third decade of May. If atypical for the region hydrothermal conditions (drought or excessive moistening) are forecasted du ring the vegetation period of millet, the highest productivity is provided by sowing in the second decade of May. Early sowing in the first decade of May causes decrease in yield at the level of 0.14 to 0.48 metric tons per hectare (Slobozhanske variety) and 0.14 to 0.48 metric tons per hectare (Lana variety); if the sowing is postponed to the first decade of June, the yield increases by 0.31 to 0.77 and 0.39 to 0.84 metric tons per hectare, respectively. Early spring and summer sowing using ordinary drill method contribute to the formation of the highest qua lity of seeds – the overall quality index was the highest at the level of 97,9 to 98,5% (Slobozhanske variety) and 98,3 to 100,0% (Lana variety).

Collection samples of the onion of varying ecological and geographical origin have been scrutinized under the conditions of Chernigiv region to establish their susceptibility to Botrytis allii Munn pathogen. It is noted that the disease develops, first of all, on samples with dry leafs colored white, and established that enhanced resistance to the pathogen is inherent in forms of anthocyanin or red coloration or dry and damp skins (Rubin, Amfora, Veselka, Mavka, Braushverska Chervona, Venta F1, Tango F1, Golubka). Sources of resistance to neck rot are indicated (Olina, Texas Curli, Violetta, Red Baron F1), which have not been damaged by the pathogen at all through the three years of study. The use of parental pars quality of such samples will enable to produce prospective breeding material at hybridization.

Р. І. Кременчук | О. І. Китаєв
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.

Oats technological indices have been analyzed. Influence of growing conditions on natural weight, kernel size, and hoodness is established. The study summary indicates essential dependence of natural weight and hoodness and precipitation at the stage of grain formation in coated grain oats varieties. Moisture supply in the period of grain formation essentially influenced the percentage of coated grains formation and natural weight score in naked grain varieties. Morphometric analyzes of oats caryopsis was completed using the method of machine vision. Correlation between technological indices and morphometric characteristics of naked and coated grain of oats was determined. Also, essential dependence of hoodness on 1000 seeds weight and the lack of essential correlation with morphometric characteristics of the calliopsis were established. Calliopsis width essentially influenced the weight of 1000 seeds. Metric indices of naked grain oats calliopsis exposed close correlation with kernel size and natural weight. Weight of 1000 seeds exposed essential varietal distinctness and was determined by genetic peculiarities of varieties

Є. О. Долматов | В. Є. Джафарова
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.
