Title: RADIATION-INDUCED MUTATIONS FOR STEM RUST RESISTANCE IN OATS

Abstract

Stem rust rcsistant viriants from earlier experiments on the induction or resistance in oats by radiation were found to result from natural field hybridization. Recent controlled experiments did, however, yield new variants at a low frequency in one instance. and no variants in another. Both experiments included over 3,000 lines from irradiated seeds. One previously unknown type of rust resistance reaction was obtained in a mutant plant. This mutant shows a temperature sensitive response for resistance to race 7A of Puccinia graminis avenae. It was suggested that some, as yet unknown, mcdifying factors mav limit the development of induced changes into mutations. (auth)
