  • Screening of wheat genotypes for leaf rust resistance

    01.06.2015· Plant breeding for disease resistance is one of the most important methods for diminishing the yield loss of wheat. Resistance expression depends on the host–parasite interaction, environmental conditions, plant growth stage and the interaction between resistance genes in wheat genome (Kolmer, 1996).
