Abstract
The two GA-insensitive dwarfing gene loci Rht-B1 and Rht-D1 were mappe d using three F-2 populations, segregating for Rht-B1c (Rht3), Rht-D1b (Rht2) or Rht-D1c (Rht10). Rht-B1c was mapped on chromosome 4BS in th e centromere region, distal and closely linked to the RFLP markers Xps r144 (11.9 cM) and Xpsr584 (17.8 cM), but proximal to Xmwg634 (30 cM). Rht-D1c, however, was found to be closely linked to the distally loca ted markers Xpsr921 (0.8 cM) and Xmwg634 (1.5 cM). The homoeologous re lationships between the GA-insensitive dwarfing genes within the Triti ceae are discussed.
