Assessment of wheat wide hybridization derivatives for agronomic traits and disease resistance in drought conditions

Aim. To determine the breeding value of wheat wide hybridization derivatives by studying resistance to diseases, protein content and yield, productivity drought index. Methods. Growing plants in favorable conditions, environments acute under infection background rusts was combined with laboratory methods for determining weight 1000 kernels content. Results. Disease has depended on pathogen species source alien variability. The index is mainly determined yield material conditions (r = –0.65***) a lesser extent depends normal 0.27**). Conclusions. Resistance leaf or yellow rust been successfully transferred from all sources involved hybridization, but stem – sample, containing translocation 1BL.1RS karyotype T. timopheevii pedigree. When material, it necessary take into account not only index, also its environments. parameters absolute should be used selection promising lines. perspective lines group disease resistance, high values WTK, content, have selected. Lines pubescence were characterized low productivity.
