  • Thesis Presentation on Molecular Mapping and Genetic Characterisation of Rust Resistance in Wheat

    mamtaThis Friday on 27/11/2015 at 10 am at the RDC Yusipang Conference Hall there will be a Thesis Presentation by Mamta Chhetri on Molecular Mapping and Genetic Characterisation of Rust Resistance in Wheat.

    Abstract: The first aspect of this investigation covers QTL analysis of triple rust resistance segregating among W195/BT-Schomburgk Selection (BTSS) recombinant inbred line (RIL) population. Three QTL each for stripe rust (QYr.sun-3BS; QYr.sun-4DL; QYr.sun-7AS), leaf rust (QLr.sun-2BS; QLr.sun-3BS; QLr.sun-4DL) and stem rust (QSr.sun-2BL; QSr.sun-4DL; QSr.sun-6AS) resistance were identified. QYr.sun-3BS, QYr.sun-4DL, QLr.sun-4DL and QSr.sun-4DL were contributed by W195, whereas other QTL were contributed by the alternate parent BTSS.

  • CSWS Non-respondent civil servants

    This is to apprise all civil servants under Ministry of Agriculture and Forests that the Royal Civil Service Commission vide letter no. RCSC/PPD/WU-3/2015/1282 dated 12th November 2015 has provided the list of civil servants (attached) under this Ministry who has not yet responded to Civil Service Welfare Scheme (CSWS) Membership despite several notifications by the Ministry and the Royal Civil Service Commission.

    In this regard, all non-respondent civil servants under this Ministry are requested to complete the following options latest by 20th December 2015 and submit to HR Division, MoAF for further submission to RCSC:

  • Molecular Mapping and Genetic Characterization of Rust Resistance in Wheat

    Friday seminar on 27th November 2015:
    Venue: RDC Yusipang.

    Abstract

    The first aspect of this investigation covers QTL analysis of triple rust resistance segregating among W195/BT-Schomburgk Selection (BTSS) recombinant inbred line (RIL) population. Three QTL each for stripe rust (QYr.sun-3BS; QYr.sun-4DL; QYr.sun-7AS), leaf rust (QLr.sun-2BS; QLr.sun-3BS; QLr.sun-4DL) and stem rust (QSr.sun-2BL; QSr.sun-4DL; QSr.sun-6AS) resistance were identified. QYr.sun-3BS, QYr.sun-4DL, QLr.sun-4DL and QSr.sun-4DL were contributed by W195, whereas other QTL were contributed by the alternate parent BTSS.

    QTL analysis was followed by detailed characterization of the resistance loci. QYr.sun-3BS explained 34-59% phenotypic variation and was chosen for characterisation at different growth stages and temperature regimes. It expressed well at the 4th leaf stage at a higher than normal temperature (21±2 ºC) for stripe rust growth. This locus was formally named Yr58. The co-located QTL for stripe rust, leaf rust and stem rust resistance in chromosome 4DL was demonstrated to correspond to the pleiotropic adult plant resistance (APR) locus Yr46/Lr67/Sr55 through linked marker genotyping. Yr58 produced infection type 23C when present singly and in the presence of Yr46 it produced infection type; 1N.These results demonstrated the interaction of APR gene Yr46in improving expression of the middle stage resistance gene Yr58. QLr.sun-2BS and QSr.sun-6AS were confirmed to be Lr23 and Sr8a, respectively,through seedling tests using relevant pathotypes. QYr.sun-7AS, QLr.sun-3BS, QSr.sun-2BL appear to be unique APR loci and need to be characterised in detail.

  • RNR Extension Manual 2016 (Diary)

    The Information and Communication Services (ICS) is in the process of compiling the updated information for the RNR Extension Manual 2016. Therefore, ICS would like to request all the departments/agencies to kindly furnish any update required with regard to their respective agencies based on RNR Extension Manual 2015 for finalisation at ics@moaf.gov.bt on or before 1 December 2015.

    ICS is looking forward for your kind support in developing and designing the manual on time. Please note that ICS will not be able to entertain any updates beyond the deadline due to time constraints.
