“…The prerequisite for the development of new competitive drought-resistant wheat cultivars is an understanding of the genetic mechanisms associated with drought stress tolerance. Previously, various genes involved in plant drought response have been distinguished and described (Ingram & Bartels, 1996;Agarwal et al, 2006;Wei et al, 2009;Huseynova, Rustamova & Mammadov, 2013;Nezhadahmadi, Prodhan & Faruq, 2013;Hassan et al, 2015;Kulkarni et al, 2017). In addition, several transcription factor families associated with drought in wheat have been identified, such as ethylene response factors (ERFs), dehydration responsive element binding (DREB), and zinc finger proteins (ZFPs) (Agarwal et al, 2006;Kulkarni et al, 2017).…”

Background Bread wheat is the most important cereal in Kazakhstan, where it is grown on over 12 million hectares. One of the major constraints affecting wheat grain yield is drought due to the limited water supply. Hence, the development of drought-resistant cultivars is critical for ensuring food security in this country. Therefore, identifying quantitative trait loci (QTLs) associated with drought tolerance as an essential step in modern breeding activities, which rely on a marker-assisted selection approach. Methods A collection of 179 spring wheat accessions was tested under irrigated and rainfed conditions in Northern Kazakhstan over three years (2018, 2019, and 2020), during which data was collected on nine traits: heading date (HD), seed maturity date (SMD), plant height (PH), peduncle length (PL), number of productive spikes (NPS), spike length (SL), number of kernels per spike (NKS), thousand kernel weight (TKW), and kernels yield per m2 (YM2). The collection was genotyped using a 20,000 (20K) Illumina iSelect SNP array, and 8,662 polymorphic SNP markers were selected for a genome-wide association study (GWAS) to identify QTLs for targeted agronomic traits. Results Out of the total of 237 discovered QTLs, 50 were identified as being stable QTLs for irrigated and rainfed conditions in the Akmola region, Northern Kazakhstan; the identified QTLs were associated with all the studied traits except PH. The results indicate that nine QTLs for HD and 11 QTLs for SMD are presumably novel genetic factors identified in the irrigated and rainfed conditions of Northern Kazakhstan. The identified SNP markers of the QTLs for targeted traits in rainfed conditions can be applied to develop new competitive spring wheat cultivars in arid zones using a marker-assisted selection approach.
