GENETIC INHIBITION OF EXPRESSION OF RESISTANCE GENE Lr23 IN WHEAT TO Puccinia recondita

Abstract

The common wheat (Triticum aestivum L.) experimental line Prelude/8* Marquis was determined to have a gene that inhibits the expression of gene Lr23 for seedling resistance to leaf rust (Puccinia recondita Rob. ex. Desm.) whereas the cultivar Prelude does not. This inhibitor had previously been reported in the cultivar Thatcher.
