ABSTRACT Aim To assess evidence for geographical and environmental range expansion through polyploidy in wild potatoes ( Solanum sect. Petota ). There are diploids, triploids, tetraploids, pentaploids hexaploids this group. Location Wild occur from the south‐western USA (Utah Colorado), throughout tropical highlands of Mexico, Central America Andes, to Argentina, Chile Uruguay. Methods We compiled 5447 reports ploidy determination, covering 185 187 species, which 702 determinations presented...
Solanum tuberosum, the cultivated potato of world commerce, is a primary food crop worldwide. Wild and potatoes form germplasm base for international breeding efforts to improve in face variety disease, environmental agronomic constraints. A series national genebanks collect, characterize distribute stimulate aid improvement. knowledge taxonomy evolution guides collecting efforts, genebank operations breeding. Past taxonomic treatments wild have differed tremendously among authors with...
Nomenclatural standards of five potato cultivars ‘Vulkan’ (WIR-108746), ‘Gejzer’ (WIR-108747), ‘Kamčatka’ (WIR-108748), ‘Severânin’ (WIR-108749), and ‘Solnyško’ (WIR-108750) bred by the Kamchatka Research Institute Agriculture (currently a branch VIR), six ‘Dačnyj’ (WIR-108751), ‘Kazačok’ (WIR-108752), ‘Morâk’ (WIR-108753), ‘Orion’ (WIR-108755), ‘Posejdon’ (WIR-108756), ‘Smak’ (WIR-108754) Federal Scientific Center Agricultural Biotechnology Far East named after A.K. Chaika, were prepared...
The taxonomy of cultivated potatoes has been highly controversial, with estimates species numbers ranging from 3 to 17. Ploidy level one the most important taxonomic characters recognize potato species, containing diploid (2n = 2x 24), triploid 3x 36), tetraploid 4x 48), and pentaploid 5x 60) cultivars. We tested environmental associations different ploidy levels in that traditionally have recognized as Linnaean taxa see whether, combination prior morphological, molecular, crossing data,...
Abstract Potato cyst nematodes ( PCN ) collected in six localities the Leningrad region of North West Russia were identified as Globodera rostochiensis pathotype Ro1 and used for subsequent resistance tests. Seventy‐nine accessions cultivated closely related wild potato species from VIR collection screened on to G. presence molecular markers H1 Gro1‐4 genes. No associations detected between level diploid tetraploid Andean Chilean landraces (indigenous cultivars) their geographical...
Thirty-six percent of the wild potato ( Solanum L. section Petota Dumort.) species are polyploid, and about half polyploids tetraploid (2n = 4x 48). Determination type polyploidy development genome concept for members traditionally has been based on analysis chromosome pairing in their hybrids and, most recently, DNA sequence phylogenetics. Based these data, designation AABB was proposed Mexican series Longipedicellata Buk. We investigated this hypothesis with genomic situ hybridization...
Increasing the resistance of varieties to diseases and pests is a priority in potato breeding. Many created Leningrad Scientific Research Institute Agriculture "Belogorka" are multi-species hybrids possessing complex most spread pathogens combination with high plasticity, which determined their zoning many regions Russian Federation. Potato different periods time this institute Ltd Breeding company "LiGa" were included marker-assisted selection 22 markers 14 R genes conferring extreme...
VIR is creating a collection of nomenclature standards for cultivars different crops in line with the provisions International Code Nomenclature Cultivated Plants (ICNCP). The nomenclatural are designed form herbarium sample cooperation authors cultivars, who select plant material each cultivar experimental field their organization and forward it to scientific together accompanying documents. Registering specimen followed by publication standards. article presents new genebank strategy...
Wild potato ( Solanum L. sect. Petota Dumort.) species contain diploids (2n = 2x 24) to hexaploids 6x 72). J.G. Hawkes classified all hexaploid Mexican in series Demissa Bukasov and, according a classic five-genome hypothesis of M. Matsubayashi 1991, members are allopolyploids. We investigated the genome composition Hawkes’s with genomic situ hybridization (GISH), using labeled DNA their putative progenitors having diploid AA, BB, or PP tetraploid AABB AAA A genomes. GISH analyses support S....
The genetic diversity of potato varieties from the VIR collection was analyzed based on microsatellite analysis. These have been bred in Russia and near-abroad countries since 1931. Application 14 highly polymorphic nuclear microsatellites (SSR) enabled complete discrimination all 113 varieties. Additionally, we studied these for distribution 8 DNA markers associated with three R-genes involved control resistance to two quarantine objects: wart Synchytrium endobioticum golden cyst nematode...
In the present paper, potato cultivars bred at Leningrad Research Institute for Agriculture “Belogorka”, were taken as an example demonstrating results of elaboration methodological approaches that are currently developed N.I. Vavilov Plant Genetic Resources (VIR) preparing nomenclatural standards and their genotyping. 2018, joint research VIR scientists breeders from “Belogorka” began in field this institute. Nomenclatural prepared according to ‘International Code Nomenclature Cultivated...
This article is devoted to designing nomeclatural standars and herbarium vouchers of raspberry cultivars bred in the M.A. Lisavenko Research Institute Horticulture for Siberia. The presents standards ‘Barnaul’skaya’, ‘Blesk’, ‘Dobraya’, ‘Zoren’ka Altaya’, ‘Illyuziya’, ‘Kredo’ ‘Rubinovaya’. work has been performed according rules recommendations outlined International Code Nomenclature Cultivated Plants guidelines developed vegetatively propagated plants. material nomenclatural should be...
Solanum tuberosum L. (common potato) is one of the most important crops produced almost all over world. Genomic sequences potato opens way for studying molecular variations related to diversification. We performed a reconstruction genomic 15 tetraploid cultivars grown in Russia using short reads. Protein-coding genes were identified; conserved and variable parts pan-genome repertoire NBS-LRR characterized. For comparison, we used additional twelve South American accessions, analysis genetic...
The common potato, Solanum tuberosum L., is the fourth most important agricultural crop worldwide. Until recently, vegetative propagation by tubers has been main method of potato cultivation. A shift interest to sexual reproduction true botanical seeds due appearance a new hybrid seed breeding strategy whose successful application for many species supported male sterility. This investigation was focused on study differences in metabolite profiles anthers at mature pollen stage from...
Male sterility in potato is little studied since traditional breeding based on the vegetative reproduction of highly heterozygous tetraploid varieties. The rapid development hybrid diploid contributes to growing interest studying male this important crop. In work, a set 6 cytoplasmic markers was employed describe genetic diversity 185 cultivars bred Russia and FSU countries. Three cytoplasm types were identified, T (40.0 %), D (50.8 %) W/ γ (8.7 which according literature are associated with...
The characterization of major resistance genes (R genes) in the potato remains an important task for molecular breeding. However, R are rapidly evolving and frequently occur genomes as clusters with complex structures, their precise mapping identification complicated time consuming. Comparative analysis root transcriptomes Solanum phureja genotypes contrasting to Globodera rostochiensis revealed a number differentially expressed genes. compiling list candidate further segregation was...
The main objectives in potato breeding are increasing yield abilities and improving resistance to numerous pathogens pests. Among them, the late blight caused by Phytophthora infestans oomycete is one of most destructive diseases both Russia worldwide. Wild relatives cultivated traditionally used as source valuable R genes conferring pathogens. Of particular interest Mexican wild species because Mexico centre origin diversity P. at same time, it diversity. S. bulbocastanum stoloniferum an...
