AAC Justice is a white-hulled spring oat ( Avena sativa L.) cultivar. It was postulated to carry the crown rust resistance gene Pc91, which effective against prevalent races on Canadian Prairies at time of its release. had very good loose and covered smut moderate most prairie stem races, intermediate in reaction barley yellow dwarf virus. has high test weight, average kernel groat percentage p...

ABSTRACT: The evolution in virulence of Puccinia coronata f. sp. avenae has challenged the genetic resistance to crown rust oat genotypes. New sources are constantly required for yield stabilization and costs reduction. This study aimed characterize genotypes disease´s productive economic impact. Experiments were conducted two environments, with without chemical control. Resistance was measured...

the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...
