Chromosomal Location of Male Fertility Restoring Genes in Six Lines of Common Wheat1

P. N. Bahl and S. S. Maan2

A monosomic set of male-sterile ‘Chris’ (Triticum aestivum L.) with T. timopheevi Zhuk. cytoplasm was used to determine the chromosomal location of Rf-genes in six male fertility restoring lines (FR-lines) of T. aestivum L. The six FR-lines were: R1-Lee (Nebraska 542437/T. aestivum ‘Lee’), R2-Sonora 64 (T. timopheevi/2*T. aestivum ‘Marquis’//‘Sonora 64’), R3 (T. timopheevi/3*T. aestivum ‘Marquis’), R4 (amphidiploid T. timopheevi-Ae. squarrosa/3*T. aestivum ‘Dirk’), R5 (T. Zhukovsky Men. and Er.,/3*T. aestivum ‘Justin’), and T. aestivum ‘Primepi’. The relative proportions of male-sterile and male-fertile plants in the F2 and F3 from monosomic F1 indicated that chromosomes 1A and 7D of R1-Lee, R2-Sonora 64, R3, R4, and R5 had Rf-genes. R2-Sonora 64 and R5 each had a third Rf-gene on chromosomes 6B and 7B, respectively. Primepi had Rf-genes on chromosomes 1B and 5D. The inheritance of fertility restoration in control crosses and in some of the noncritical crosses indicated that R1-Lee, R2-Sonora 64, and R5 each had three Rf-genes, and R3, R4, and Primepi each had two. The deficiency of certain chromosomes influenced the penetrance and expressivity of the Rf-genes in certain crosses.
