The winter wheat ( Triticum aestivum L.) lines NB474‐23 (‘NuSky’/6*‘McNeal’) (Reg. No. GP‐866, PI 660648) and NB475‐12 (‘Paul’/6*McNeal) (Reg. No. GP‐867, PI 660649) were developed by backcrossing the winter allele vrn‐A1 into the hard red spring wheat variety McNeal. Both lines are winter habit, although their winter survival is lower than that of the winter wheat cultivars. The spring wheat lines NB481‐23‐1 (‘Choteau’/6*‘Yellowstone’) (Reg. No. GP‐868, PI 660650) and NB489‐54‐1 (‘Reeder’/6*NuSky) (Reg. No. GP‐869, PI 660651) were developed by backcrossing the spring allele Vrn‐A1 into the winter wheat cultivars Yellowstone and NuSky, respectively. Spring wheat lines NB085WS03686 (Choteau/6*Paul) (Reg. No. GP‐870,PI 660652) and NB085WS03690 (Choteau/6*Paul) (Reg. No. GP‐865, PI 660647) were developed by backcrossing the spring allele at Vrn‐A1 into the winter wheat cultivar Paul. Although these four lines are all spring habit, their heading date is delayed relative to that of the spring wheat cultivars. All six lines will provide spring wheat and winter wheat breeding programs with access to genes from elite cultivars possessing the alternate growth habit.
