Not AvailableMonosomic analysis was used to locate genes for several qualitative traits in chromosomes of a wheat-rye recombinant, Selection-26 (Sel-26), using the monosomic series of cv. Chinese Spring. The study revealed that the anthocyanin pigmentation in leaf sheath is inherited as a single dominant gene in chromosome 18. The character hairy rachis node is controlled by two nonlinked duplicate genes in chromosomes 5A and 7D. The symbols Hrn 1 and Hrn 2 are proposed for these two loci. The straight upper part of glume of Sel-26 is due to a single dominant gene in chromosome 68. The gene symbol Gc (glume curvature) is proposed for this character. Three major genes governing hairy glume phenotype have been identified, two for hairiness in chromosomes 1A and 2A, and one recessive gene for glabrous glumes in 4A. Modifiers in 68 and 78 are also reported for this character. Aminor recessive gene for red grain colour has been detected inchromosome 4A of Sel-26, presumably contributed by the rye parent and a modifier in 5A. Using the phenol test, the tryosinase producing gene has been mapped in ch Print ISSN : 0019-5200romosome 68 for glume character and in 48 for rachisNot Availabl
