Similarly, Kerber and Green () described an intergenomic suppression of a rust-resistance gene in genome D by gene(s) in genome A or B. Intergenomic suppression of disease-resistance genes is a common phenomenon in wheat and related › 百度文库 › 互联网. After treatment of seven varieties with nitroso-methylurea, nitrosoethylurea and dimethyl sulfate, mutant lines were selected on the basis of economic qualities such as high yield and disease resistance. Even in the F5 a sufficiently large percentage of chromosome rearrangements were observed in the PMCs of most of the mutants to necessitate further selection prior to :// In wheats carrying an additional chromosome from a related species, the alien chromosome is usually transmitted to 30% of the selfed progeny. A. sharonensis chromosome 4Sl ensures its own transmission so that self pollination of a monosomic addition for 4Sl results in ∼% disomic additions.

Powdery mildew resistance gene Pm4b, originating from Triticum persicum, is effective against the prevalent Blumeria graminis f. tritici (Bgt) isolates from certain regions of wheat production in China. The lack of tightly linked molecular markers with the target gene prevents the precise identification of Pm4b during the application of molecular marker-assisted selection (MAS).
In wheat and tobacco, radiation has been utilized for transmitting disease-resistant genes from wild species to cultivated ones by means of chromosomal translocations.

A uniform system for Selection is an integral component in plant breeding, which ensures the progressive values of the breeding material, in terms of yield and quality.
However, selection is influenced by the environment in any given growing season. The observed phenotype is a product of the genotype (G), the environment (E), and/or genotype × environment (G×E). Therefore, phenotypic selection is not always the /marker-assisted-breeding-in-wheat.
