A genetic collection of monosomic and ditelosomic lines of common wheat varieties Saratovskaya 29 and Diamant were obtained in ICG SB RAS. Also we are supporting a series of lines on the aneuploids of cv. Chinese Spring, developed by E. Sears. On the basis of the monosomic lines, sets of inter-varietal and alien substitutions of individual chromosomes or their fragments were obtained with the use of different varieties of Triticum aestivum L. and representatives of other taxonomic groups (Secale cereale L., Aegilops tauschii Coss., Triticum. timopheevii Zhuk.). Sets of aneuploids and substitution lines were used for studying genetic effects of individual chromosomes on manifestation of agronomically useful traits, localization and mapping genes. Special attention has been paid to development and effectiveness evaluation of methods of task-oriented and accelerated transfer of chromosomes or their fragments which contained desirable genes from varieties and related species to wheat genome
