Study of introgression lines of common wheat Triticum aestivum/Triticum miguschovae for resistance to leaf rust

Abstract

The evaluation of resistance to leaf rust, the cytological and molecular analysis of 106 introgression lines of common wheat obtained on the basis of the synthetic form Triticum miguschovae Zhir were performed. Cytological stability of lines was established. 53 lines with high and 23 with medium resistance to leaf rust were selected. Two lines with the Lr39 gene and 26 lines with the Lr50 gene were identified with the use of molecular markers. Other resistant lines can presumably carry genes for resistance to leaf rust other than Lr39 or Lr50. Plant resistance to pathogens and other biotic stressesConflict of interest.
