Description of Susceptibility of Wheat Specimens from the World Collection of Vir (All-Union Institute of Plant Growing) to Breeds of Stem and Brown Mildew (Rust) (Methodological Aids for Breeders)

摘要

Wheat breeding for resistance to mildew breeds can be more effective if resistant varieties and forms are used as initial parent pairs for crosses. The work was done with specially selected specimens of spring and winter wheat (totalling 830 specimens) suitable for use in different zones of the country. A study of the breed composition of brown and stem mildew of wheat in our country enabled us to discover breeds with a broad spectrum and breeds that may grow in the next few years in view of the addition of new varieties of wheat.
