Comment

See Lr19, reaction to Puccinia triticina. Sr25/Lr19 often show complete linkage in wheat {956}.
Knott {681} obtained two mutants (28 and 235) of Agatha with reduced levels of yellow pigment in the flour. One of these mutants lacked Sr25. Marais {890} reported that a gene very similar to Sr25 was present in the putative Inia 66 x Thin. distichum derivative, Indis. Marais {890,892} also obtained mutants with reduced yellow pigment in Indis derivatives and some of these lacked Sr25.
