• Chromosomal location of genes for fertility-restoration, awnlessness, spelta-type ear and red coleoptile color of Triticum spelta var. duhamelianum, an effective fertility- restorer for the timopheevi cytoplasm, was determined by monosomic analysis. The results can be summarized as follows:T. spelta var. duhamelianum carries a dominant fertility-restoring gene Rf3 on its chromosome 1B. Chromosome 7D exerts a weak suppressing effect to this gene. Awnlessness is mainly due to an epistatic inhibitor B1 in chromosome 5A, while chromosome 6D has a promoting effect on awn development. As to the ear type, chromosome 5A carries a spelta gene q1, whereas chromosomes 2D and 3D possess some modifiers to this gene. Red coleoptile color is produced by genes in chromosomes 7A and 7D, while five other chromosomes, 2A, 2B, 2D, 3B and 6A, carry weak suppressors.
