Description:
The donor of the FT-A2 allele was the T. turgidum ssp. durum spring wheat landrace Gredho (PI 532239) from Oman. Gredho was crossed with the tetraploid variety Kronos, and then backcrossed four more times to Kronos. Homozygous BC4F5 lines were selected and are the deposited material. In each generation the presence of the FT-A2 A10 allele was confirmed using diagnostic molecular markers for the mutation encoding the characteristic D10A amino acid change.
