Notes:
Summary By means of F1 monosomic analysis, genes governing several morphological traits were located in a strain of Triticum macha (2n=42). T. macha was crossed with all the 21 monosomic lines of PbC 591 (T. aestivum) and with a disome of PbC 591. Critical lines possessing the following recessive characters of T. macha were identified by comparing the monosomic F1's with the control cross. (1) The gene which controls compactness of the spike of T.macha is located on chromosome 6B. A gene symbol C m is proposed for this character to distinguish it from C gene of T.compactum, which is located on 2D. (2) The glabrous nature of the outer glume is controlled by chromosomes 1A, 1B, 6B and 5D. (3) Genes on 6B, 3D and 5D govern the closed nature of spikelet at maturity. (4) The flat nature of the rachis internode of T.macha, in contrast to the swollen rachis of PbC 591, is under the control of chromosomes 2A, 1B, 6B and 6D. (5) Winter growth habit is controlled by genes on 5A, 2B, 6B and 5D; 5D being the most potent in inducing lateness.
