| Outline of Final Research Achievements |
I tried to identify novel flowering genes in tetraploid wheat accessions.
I identified an early flowering allele of Vrn-A3 that TN26 (Triticum turgidum L. ssp. dicoccum) harbors by QTL analysis and sequence analysis. From the results of expression analysis it was also suggested that the early flowering trait of TN26 was caused by the cis-element GATAbox at a promoter region of the novel Vrn-A3 allele in TN26. From the results of this study it was suggested that the novel Vrn-A3 insertion allele is useful for breeding of early-flowering durum wheat cultivar. From the investigation for an earliness per se QTL in TN26 I could find unique trait of the QTL, which shortens the duration from flag-leaf expansion to flowering and affects ear shape.
