To determine the number of genes for resistance to leaf and stem rust in some accessions of three wild species, Triticum monococcum, Triticum dicoccoides, and Triticum timopheevii, that are closely related to wheat, and to transfer the genes to durum and bread wheats for use by wheat breeders. To transfer genes for rust resistance to wheat from three more distantly related species, Triticum ovatum, Triticum triaristatum and Triticum cylindricum. To study the suppressers of rust resistance in the D-genome chromosomes of bread wheat and attempt to find non-suppressing alleles so that resistance can be transferred to bread wheat.
