Abstract :

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 .
