C. А. Корнеева | Є. М. Седов
Breeding of columnar type apple varieties has been carried out at VNIISPK since 1984. The possibility of grow-ing of columnar type apple varieties in the crown of winter hardy semi-dwarf rootstock 3-4-98 by S. N. Stepanov’s breeding is being studied in different density of planting in the orchard (3 x 1,0 m; 3 x 1,5; and 3 x 2,0 m). The inves tigation of winter hardiness, cropping power, fruit mar ketability and biochemical composition allowed releasing two varieties «Poesia» and «Priokskoye» for state trials.

Lücking,Robert | Aime,M. | Robbertse,Barbara | Miller,Andrew | Ariyawansa,Hiran | Aoki,Takayuki | Cardinali,Gianluigi | Crous,Pedro | Druzhinina,Irina | Geiser,David | Hawksworth,David | Hyde,Kevin | Irinyi,Laszlo | Jeewon,Rajesh | Johnston,Peter | Kirk,Paul | Malosso,Elaine | May,Tom | Meyer,Wieland | Öpik,Maarja | Robert,Vincent | Stadler,Marc | Thines,Marco | Vu,Duong | Yurkov,Andrey | Zhang,Ning | Schoch,Conrad
True fungi (Fungi) and fungus-like organisms (e.g. Mycetozoa, Oomycota) constitute the second largest group of organisms based on global richness estimates, with around 3 million predicted species. Compared to plants and animals, fungi have simple body plans with often morphologically and ecologically obscure structures. This poses challenges for accurate and precise identifications. Here we provide a conceptual framework for the identification of fungi, encouraging the approach of integrative (polyphasic) taxonomy for species delimitation, i.e. the combination of genealogy (phylogeny), phenotype (including autecology), and reproductive biology (when feasible). This allows objective evaluation of diagnostic characters, either phenotypic or molecular or both. Verification of identifications is crucial but often neglected. Because of clade-specific evolutionary histories, there is currently no single tool for the identification of fungi, although DNA barcoding using the internal transcribed spacer (ITS) remains a first diagnosis, particularly in metabarcoding studies. Secondary DNA barcodes are increasingly implemented for groups where ITS does not provide sufficient precision. Issues of pairwise sequence similarity-based identifications and OTU clustering are discussed, and multiple sequence alignment-based phylogenetic approaches with subsequent verification are recommended as more accurate alternatives. In metabarcoding approaches, the trade-off between speed and accuracy and precision of molecular identifications must be carefully considered. Intragenomic variation of the ITS and other barcoding markers should be properly documented, as phylotype diversity is not necessarily a proxy of species richness. Important strategies to improve molecular identification of fungi are: (1) broadly document intraspecific and intragenomic variation of barcoding markers; (2) substantially expand sequence repositories, focusing on undersampled clades and missing taxa; (3) improve curation of sequence labels in primary repositories and substantially increase the number of sequences based on verified material; (4) link sequence data to digital information of voucher specimens including imagery. In parallel, technological improvements to genome sequencing offer promising alternatives to DNA barcoding in the future. Despite the prevalence of DNA-based fungal taxonomy, phenotype-based approaches remain an important strategy to catalog the global diversity of fungi and establish initial species hypotheses.

???????, Yzeiraj, M., ?.
Purpose. Grapevines (Vitis spp.) are affected by many viral diseases which cause serious pathological problems. GLRaV-3 is among the most widespread leafroll viruses, while Grapevine Fanleaf Virus (GFLV) is a destructive pathogen which reduces the lifespan of grapevine. Considering the impact and the spread of these diseases, our objective was to analyse the presence of these two viruses in several grapevine varieties in grapevine collection at ATTC Vlore. Data gathered from plant pathogens serve to better understand and prevent the spread of pathogens, as a mandatory rule for the quality control of certified plant material during vegetative propagation. Method. The presence of two common viruses were tested using virus specific primers; LC1/LC2 primer pair designed from the hHSP70 gene for detecting Grapevine Leafroll-associated Virus-3 (GLRaV3) and C3390/H2999 primer pair, designed from coat protein coding regions for detecting Grapevine Fanleaf Virus (GFLV), in six varieties; ?Merlot?, ?Kallmet?, ?Shesh i zi?, ?Shesh i bardh??, ?Debin??, and ?Pul?z?, provided through a randomised sampling procedure. One Step Reverse Transcription Polymerase Chain Reaction assay was used to detect the viral presence. Results showed a high (100%) prevalence of GLRaV3 virus in all of analysed samples, as the most frequent among the two pathogens. Analysis for of GFLV virus showed low infection rate, being present in only one sample. Conclusions. We herein show an efficient, fast and reproducible method for detecting grapevine viruses through one step RT-PCR. Our results suggest that sampling of the infected plant material should be avoided due to the presence of viral infections. | ????. ??????? ?????????

Викладено історію становлення вітчизняного сортовивчення яблуні, у розвитку якого провідну роль відіграли українські садоводи Лев Платонович та Володимир Львович Симиренки. Доведено, що використання сучасних методик дослідження особливостей росту і плодоношення дерев яблуні (на прикладі нових імунних до парші сортів орловської селекції, Росія) дає можливість визначити для умов Лісостепу України скороплідні сорти, які інтенсивно нарощують урожайність у перші роки плодоношення та формують плоди високих товарних і смакових якостей.
