  • Wheat: Pre-breeding Lines with Good Grain Yield Potential
  • Wheat Pre-breeding Lines with Good Grain Yield Potential


    Wheat pre-breeding lines derived from top-crosses using one germplasm bank accession crossed to an elite line, and then crossed to a second elite line. The accessions were selected as promising sources for use in breeding for improved grain yield of wheat. The pre-breeding lines were identified based on field trials under well-irrigated conditions during seasons 2015-16 and 2016-17 in Mexico. One line has significantly higher yield than best check, Reedling.

    Product details and features

    1. List of lines with phenotypic data is available including checks, and elite lines as reference materials: Two pre-breeding lines had grain yield advantage (8-11 %) over best check variety under irrigated environment.Link
    2. Genotypic data are available.Link
    3. Ability to sort by various traits, e.g. Days to heading (DH), Days to maturity (DM), Height (H), Yield (Y) (Available November 2017)

  • Comments

    These materials are suited for research or for large breeding programs interested in exploring exotic germplasm sources. These germplasm lines were evaluated under drought, heat and irrigated conditions. During the selection process, materials were rejected if susceptible to rusts or if they had other undesirable characters. These products can be used as bridging germplasm by interested researchers to increase wheat productivity.

    Availability

    Currently available. Seeds of these entries are available from CIMMYT’s germplasm bank. They can be requested as International wheat pre-breeding nursery-1 (IWPN-1).



    Primary Users

    Wheat breeders; geneticists investigating genetic gain for grain yield; researchers studying physiological mechanisms of grain yield; researchers engaged in gene discovery for improving wheat yield.
