Abstract
Biochemical markers associated with homoelogous chromosome groups 3 and 7 of Triticum aestivum L. have been investigated in genetic stocks carrying chromosomes or chromosomal segments of the same homoeology groups from Agropyron elongatum and Secale cereale.
Chromosomes 3Ag of Agropyron and 3R of Secale control proteins a3 and b3 with the same properties as proteins 5, 6 and 7 associated with 3B and 3D of Triticum. It is concluded that genes for proteins 5, a3 and b3 are located in segments proximal to the centromere in the β arms of chromosomes 3D and 3Ag, respectively. Proteins 3, 4 and 11, controlled by 7D-short arm of Triticum, are replaced by proteins a7, b7 and c7, when that chromosome is replaced by 7 Ag. Genes for these proteins are located proximal to the centromere in the short arms of chromosomes 7D and 7 Ag. Finally, a gene that controls sterol esterification is similarly located in the short arms of chromosomes 7D and 7 Ag
