Monosomic analysis conducted on a wheat-rye recombinant(Sel-26) to assign majorgenes for yield and yield attributing characters to its specific chromosomes by employing Chinese Spring monosomic series revealed that chromosomes 3A, 3D and 4A of Sel-26 carry genes which enhance yield while 6B harbours genes which decrease the yield. Chromosomes 5A, 5B and 6B of Sel-26 have major recessive genes for low seed weight along with minorgenes in 4B, 4D, 5D and 7D. It was indicated that grains per spike increased due to genes on chromosome 6B and reduced by those on chromosome 5B. Two chromosomes, 4A and 4B, carry genes for higher tiller number in Sel-26.
