Description:
The T. monococcum PI 306540 (Am) x Kronos (PI 576168) F1 was crossed as bridge with hexaploid wheat variety Clear White (PI 635044). The F1 plant was backcrossed three times to common wheat Fielder. BC3F1 plants carrying the 7Am (7A) substitution including Sr22b were self-pollinated and homozygous BC3F2 plants were selected with molecular markers. We are providing the BC3F4 seeds derived with the plants homozygous for the 7Am (7A) chromosome substitution.
