Single Nucleotide Polymorphism of the chickpea gene encoding acetohydroxyacid synthase: molecular-genetical analysis

Abstract

Aim. Chickpea AHAS gene molecular-marker analysis. To achieve this aim following tasks were set: chickpea AHAS gene SNP markers research and development, chickpea varieties and samples genotyping by the markers. Methods. CTAB method of DNA isolation and purification, real-time polymerase chain reaction. Results. Chickpea AHAS1 gene KASP gene specificity was found: there were no DNA amplification with lens and maize samples observed. Three Ukrainian chickpea varieties and 28 ICRISAT collection samples KASP genotyping detected only wild-type C-allele. Authors own SNP markers 58 chickpea samples genotyping showed that AHAS1 gene within samples was homozygous, no mutant T allele was detected. Conclusions. 31 chickpea samples contained wild-type C-allele by KASP genotyping, which is associated with imidazoline herbicide susceptibility. 58 chickpea samples contained C-allele by authors own SNP markers genotyping. Mutant T-allele that is associated with tolerance absence indicates researched samples imidazole herbicide tolerance low level.
