The genetic nature of mutations of a gene for yellow pigment linked to Lr19 in 'Agatha' wheat

Abstract

In previous work, two mutations that resulted in lower levels of yellow pigment in flour had been produced in 'Agatha' wheat which carries a wheat–Agropyron translocation. To determine whether the mutations involved the gene for yellow pigment or a suppressor at another locus, the two mutants were crossed with 'Neepawa' and 'Manitou.' Segregation for a suppressor did not occur in the F2 and F3 generations. Thus it appeared that the mutations involved the pigment locus.Key words: Triticum, translocation, yellow pigment, Agropyron.
