(Reg.no. GP-343,PI560335)is a durumwheat
KS91WGRC14
(Triticum turgidum L. var. durum Desf.) germplasm line
homozygousfor T1BL'1RS wheat-rye (Secalecereale L-)
chromosometranslocation, developed cooperatively by the
KansasAgricultural Experiment Station, the Wheat Genetics
ResourceCenter, KansasState University, USDA-ARS, and
the Technical University of Munich. It was releasedby the
KansasAgricultural Experiment Station and the Wheat Genetics ResourceCenter, KansasState University, as a germplasm in February1992.
KS91WGRC14 is a BC'Fr-derived line from the cross
'Cando'"21'Yeery'.Candois a durumwheatcultivar,andVeery
is a breadwheatcultivar carryinga TIBL'1RS wheat-ryechromosome translocation.KS91WGRC14 is the bulked, selfed
progenyof a BC,F plant that had ?t:28 chromosomesand
was tromozygousfor TLBL'1RS, basedon C-bandinganalysis
( 1 ).
KS91WGRC14is resistantto culturesof the stem rust fun-
trophoreticbandscodedby the secalinlocuson 1RS (2)Small quantities(3 g) of seedof KS91WGRC14are available upon written request.It is requestedthat appropriaterecognition of sourcebe given when this germplasmcontributes
to researchor developmentof new cultivars. Seedstocksare
