Kazakh Research Institute of Agriculture and Plant Growing developed bread wheat lines through wide crosses with Aegilops cylindrica Host, Ae. triaristata Willd., Triticum timopheevii (Zhuk.) Zhuk., T. militinae Zhuk. & Migush., T. kiharae Dorof. & Migush., and T. dicoccum (Schrank) Schübl. The best lines went through a multilocational evaluation process and were included in the Facultative and Winter Wheat Observation Nursery and submitted to the USDA for registration. We identified nine superior lines for potential use in research and breeding. The registered winter wheat lines combine the following agronomic traits: ‘Bezostaya-1’*2/Ae. cylyndrica (KAZ1718, Reg. no. GP-1056, PI 690701) with resistance to stripe rust, common bunt, and powdery mildew, thicker roots, and long fertile spike; Bezostaya-1/T. militinae-6 (KAZ1721-6, Reg. no. GP-1057, PI 690702) with resistance to stripe rust and common bunt and superior grain quality; Bezostaya-1/T. militinae-4 (KAZ1721-4, Reg. no. GP-1058, PI 690703) with resistance to stripe rust and common bunt, longer roots, large grain, high yield, and superior grain quality; and ‘Zhetysu’/T. militinae (KAZ1671, Reg. no. GP-1059, PI 690704) with resistance to powdery mildew and longer roots. Spring wheat lines combine the following characteristics: ‘Kazakhstanskaya-25’/T. timopheevii-1 (KAZ43, Reg. no. GP-1051, PI 690709) is resistant to stripe rust, is moderately resistant to common bunt, and has longer roots and high grain yield; 6625/T. timopheevii-2 (KAZ41, Reg. no. GP-1055, PI 690707) and 6631/T. timopheevii (KAZ44, Reg. no. GP-1052, PI 690710) are resistant to all rusts and have high grain yield; 6631/T. militinae (KAZ45, Reg. no. GP-1053, PI 690711) is resistant to leaf and stem rust and has high protein content; and ‘Kazakhstansakaya-10’/T. dicoccum (KAZ42, Reg. no. GP-1054, PI 690708) is resistant to leaf and stem rust and common bunt, had the highest grain yield, and has superior bread-making quality. All germplasm represent new genetic diversity for use in breeding. © 2021 The Authors. Journal of Plant Registrations
