ОТБОР УСТОЙЧИВЫХ К М-ВИРУСУ ГЕНОТИПОВ КАРТОФЕЛЯ (SOLANUM TUBEROSUM) C ПОМОЩЬЮ ПЦР

The methods for identifying M-virus resistance genes of potato were developed.Gene Gm of extreme PVM resistance is rare and available for the present only in breeding material.On the contrary, hypersensitivity gene Rm is quite widely repre­sented in Belarusian and foreign potato cultivars providing their resistance to this pathogen.Potato cultivars and hybrids, se­lected for the availability of markers GP250510, GP283320, UBC8221079 to gene Rm and marker SC878885 to gene Gm, are the valuable donors of resistance to this virus and are recommended for use in breeding.Разработаны методы идентификации генов устойчивости к М-вирусу картофеля. Показано, что ген Gm крайней устойчивости к M-вирусу является редким и присутствует пока только в селекционном материале. Ген сверхчувствительности Rm, напротив, достаточно широко представлен в со­ртах картофеля, что обеспечивает их устойчивость к М-вирусу.Выделенные по наличию маркеров GP250510, GP283320, UBC8221079 к гену Rm и маркера SC878885 к гену Gm сорта и гибриды картофеля являются ценными донорами устойчивости к этому патогену и могут быть рекомендованы для ис­пользования в селекции

The collection of potato cultivars as a source for breeding for high yield, earliness, and resistance to late blight, virus diseases and Globodera rostochiensis Woll

Background. The article presents information on the results of screening potato cultivars for major commercial traits: earliness, high yield, high starch content, resistance to late blight (Phytophthora infestans (Mont.) de Bary), virus diseases and potato nematode (Globodera rostochiensis Woll. (Ro1)). Materials and methods. VIR’s collection of domestic and foreign potato cultivars served as the material for this research. The study was conducted in accordance with the guidelines developed at the Potato Genetic Resources Department of VIR. Results and conclusion. The analysis of pedigrees helped to select source material for the main trends of domestic potato breeding. Data of a number of cultivars identified by analyzing progenies from self-pollination are presented in the paper. Potential sources of major commercial traits were found: cvs. ‘Banba’ (k-25222), ‘Bastion’ (k-25198), ‘Belukha’ (k-25146), ‘Charoit’ (k-25221), ‘Colleen’ (k-25224), ‘Gala’ (k-25270), ‘Geyzer’ (k-25266), ‘Gornyak’ (k-25311), ‘Larets’ (k-25211), ‘Leoni’ (k-25244), ‘Manifest’ (k-25265), ‘Meteor’ (k-25212), ‘Nur-Alem’ (k-25253), ‘Prizer’ (k-25217), etc. were identified as high yield sources; cvs. ‘Aktyubinskiy-2’ (k-25300), ‘Alaya roza’ (k-25144), ‘Charaўnik’ (k-25139), ‘Darnitsa’ (k-25179), ‘Lad’ (k-25180), ‘Levada’ (k-25121), ‘Maksimum’ (k-25136), ‘Palitra’ (k-25123), ‘Tamyz’ (k-25307), ‘Universal’ (k-25137), ‘Vektor’ (k-25200), ‘Vytok’ (k-11897), ‘Zarevo’ (k-10773) and ‘Zholbarys’ (k-25155) as sources of high starch content; cvs. ‘Aral’ (k-25107), ‘Aymurat’ (k-25248), ‘Bastion’ (k-25198), ‘Berkut’ (k-25250), ‘Gastsinets’ (k-25264), ‘Musinskiy’ (k-25312), ‘Nur-Alem’ (k-25253), ‘Rapsodiya’ (k-25130), ‘Senim’ (k-25306), ‘Sunkar’ (k-25258), ‘Tamyz’ (k-25307), ‘Udovitskiy’ (k-25260), ‘Vektor’ (k-25200), ‘Velikan’ (k-25201), ‘Zholbarys’ (k-25155) and ‘Zvezdochka’ (k-25209) as sources of late blight resistance; cvs. ‘Adil’ (k-25112), ‘Azart’ (k-25196), ‘Bastion’ (k-25198), ‘Charoit’ (k-25221), ‘Favorit’ (k-25132), ‘Gastsinets’ (k-25264), ‘Geyzer’ (k-25266), ‘Krasavchik’ (k-25210), ‘Maksimum’ (k-25136), ‘Malyshok’ (k-25189), ‘Manifest’ (k-25265), ‘Nadezhda’ (k-25213), ‘Nur-Alem’ (k-25253), ‘Pamyati Lorkha’ (k-25214), ‘Rapsodiya’ (k-25130), ‘Senim’ (k-25306), ‘Sirenevyy tuman’ (k-25143), ‘Sultan’ (k-25131), ‘Shchedrik’ (k-25126), ‘Tekes’ (k-25173), ‘Velikan’ (k-25201), ‘Volat’ (k-25263), ‘Zhemchuzhina’ (k-25128), etc. as sources of field resistance to virus diseases.
