Title	Genetic control for resistance to leaf rust in wheat-Agropyron lines: Agro 139 and Agro 58
Journal	Theoretical and Applied Genetics
Year	1995
Volume	90
Pages	618-620
Author	Sibikeev S Voronina S Krupnov V
Abstract	Leaf rust resistance lines of Triticum aestivum carry highly effective Lr genes from Agropyron intermedium (Host) Beauv This Agro 58 and Agro 139 resistance segregated independently of Agropyron leaf-rust resistance genes Lr-19, Lr-24 and Lr-9 from Ae umbellulata Monosomic analysis showed that the Lr gene in Agro 139 was incorporated into wheat chromosome 6D C-banding analysis could not determine the C-banding pattern of A. intermedium in wheat-Agropyron lines Agro 58 and Agro 139. It is assumed that the transfers occurred from the euchromatin regions of the Agropyron chromosomes to the euchromatin regions of the wheat chromosomes. It is suggested that the Lr gene from Agro 139 be designated LrAg(i)-l and the Lr gene from Agro S8 designated LrAg(i)-2.
