Abstract :
<p>The objective of work was to identify effective yellow and own leaf rust resistance genes for the improvement of wheat< /> quality in Azerbaijan. 61 ead wheat (Triticum aestivum L.) genotipes were taken from Research Institute of Crop< /> Husbandry (Baku, Azerbaijan). PCR amplification of the SSR marker located on the chromosome 7D Xgwm295 linked to the Yr18 gene showed a< /> fragment of 250 bp only in 40 genotypes. SSR marker XGWM582 in the chromosome 1B, associated with the gene Yr9 amplified a band of 150 bp< /> in 93% of genotypes. The STS markers Lr34/csLV34a and Lr34/csLV34b were proved as effective markers for the identification and selection of Lr< /> 34 gene. The csLV34a allele (229–bp) was linked in repulsion with Lr34 presented in 21 genotypes, whereas the csLV34b allele (150–bp) was linked< /> in coupling with Lr34 in only 9 genotypes. 2 genotypes contain both alleles linked to the Lr34 . </p>
