Genetic control for resistance to leaf rust in wheat-Agropyron lines: Agro 139 and Agro 58

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-l9, Lr-24 and Lr-9 from Ae. umbellulata. Monosomic analysis showed that th...

Description
Summary: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-l9, 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)-1 and the Lr gene from Agro 58 designated LrAg(i)-2.
