KS91WGRC14 (Reg. no. GP-343, PI 560335) is a durum wheat (Triticum turgidum L. var. durum Desf.) germplasm line homozygous for T1BL-1RS wheat-rye (Secale cereale L.) chromosome translocation, developed cooperatively by the Kansas Agricultural Experiment Station, the Wheat Genetics Resource Center, Kansas State University, USDA-ARS, and the Technical University of Munich. It was released by the Kansas Agricultural Experiment Station and the Wheat Genetics Resource Center, Kansas State University, as a germplasm in February 1992. KS91WGRC14 is a BQFj-derived line from the cross 'Cando'*2/'Veery'. Cando is a durum wheat cultivar, and Veeiy is a bread wheat cultivar carrying a T1BL-1RS wheat-rye chromosome translocation. KS91WGRC14 is the bulked, selfed progeny of a BC,F2 plant that had 2n = 28 chromosomes and was homozygous for T1BL-1RS, based on C-banding analysis (1). KS91WGRC14 is resistant to cultures of the stem rust fungus Puccinia graminis Pers.: Pers. that are avirulent to the gene Sr31 located on IRS. It is resistant to cultures of the powdery mildew fungus (Erysiphe graminis DC. f. sp. tritici Em. Marchal) that are avirulent to the gene Pm8 located on IRS. KS91WGRC14 also produces polyacrylamide gel electrophoretic bands coded by the secalin locus on IRS (2). Small quantities (3 g) of seed of KS91WGRC14 are available upon written request. It is requested that appropriate recognition of source be given when this germplasm contributes to research or development of new cultivars. Seed stocks are maintained by the Wheat Genetics Resource Center, Department of Plant Pathology, Throckmorton Hall, Kansas State University, Manhattan, KS 66506-5502.
