| Outline of Final Research Achievements |
The applicant produced "Multiple Synthetic Wheat (MSD) Population" which included intraspecific variation of wheat-related wild species, Aegilops tauschii, in a practical wheat genetic background. The MSD population was cultivated in the heat-stressed field in Agricultural Research Corporation (ARC) in Sudan, and together with the breeders, plants showing vigorous growth were selected. We confirmed that the heat tolerance of these genotypes even under controlled high temperature condition in chambers. Meanwhile, 400 individuals were randomly selected from the MSD population, cultivated in three sites of ARC, and the agronomical traits were measured. In addition, these lines were genotyped with a large numbers of markers. The high-temperature resistant wheat breeding platform constructed in this study is useful for selection and marker assist selection of high temperature tolerant cultivars and for elucidation of high temperature tolerance mechanism.
