“…First, to investigate the polymorphism between the parents (Kavir and Badia), a large number of codominant SSR markers and several types of dominant markers including intersimple sequence repeat (ISSR), expressed sequence tag (EST), transposable element (TE), start codon target (SCoT), CAAT box‐derived polymorphism (CBDP), inter‐retrotransposon amplified polymorphism (IRAP), random amplified polymorphic DNA (RAPD), intron–exon splice junctions (ISJ), inter‐primer binding site (iPBS), iPBS‐iPBS combined and ISSR‐iPBS combined were used. The criteria for the selection of random markers were polymorphic information content (PIC) and the number of observed alleles in previous research (Makhtoum et al, 2021). Finally, the markers that showed polymorphism between the parents were used to determine the genotype of the F 8 population.…”

Spot form net blotch (SFNB) is one of the most important barley diseases in the world; abiotic stresses caused by climate change are also a problem for cultivation of cereals, including barley, on a global level. Identifying stable genomic regions associated with resistance to SFNB in different temperature conditions at the reproductive stage can accelerate the process of producing new cultivars resistant to this disease. In this study, 103 F 8 lines, resulting from the cross of cultivars Kavir and Badia, were cultivated in three years on three different dates. After artificial inoculation with Pyrenophora teres f. maculata Gonbad Kavous isolate, the plants were evaluated at the adult stage. The planting dates were chosen so that during early, conventional and delayed planting dates, the reproductive stage of the lines coincided with cold, nonthermal and heat stress conditions, respectively. A genome-wide composite interval mapping method was used to identify quantitative trait loci (QTLs) controlling SFNB and estimate the effect of each of them. In the cold, non-thermal and heat stress conditions at the reproductive stage, three (three major), four (two major) and six (one major) stable resistance QTLs against SFNB were detected, respectively. The stable QTLs of resistance including QRPtma-2H, QRPtma-3H and QRPtma-7H were located on chromosomes 2H, 3H and 7H, respectively. After flanking markers confirm the resistance of QTLs to SFNB, the SCoT7-C, ISJ17-B and Bmac0144k markers can be used in the screening resistance of cultivars under non-thermal and heat stress conditions. Moreover, the Bmac0282b and Ebmatc0016 markers can be used for screening resistance of cultivars under cold stress conditions in marker-assisted selection projects.

“…QTLs identified under salinity stress on chromosome 4 were associated with spike numbers [ 23 ]. Other studies identified QTL for many traits related to salinity abiotic stress [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Makhtoum et al investigated the Iranian barley population using 103 samples from F8 families derived from the cross of two cultivars of Badia×Kavir.…”

Abiotic stresses cause a significant decrease in productivity and growth in agricultural products, especially barley. Breeding has been considered to create resistance against abiotic stresses. Pyramiding genes for tolerance to abiotic stresses through selection based on molecular markers connected to Mega MQTLs of abiotic tolerance can be one of the ways to reach Golden Barley. In this study, 1162 original QTLs controlling 116 traits tolerant to abiotic stresses were gathered from previous research and mapped from various populations. A consensus genetic map was made, including AFLP, SSR, RFLP, RAPD, SAP, DArT, EST, CAPS, STS, RGA, IFLP, and SNP markers based on two genetic linkage maps and 26 individual linkage maps. Individual genetic maps were created by integrating individual QTL studies into the pre-consensus map. The consensus map covered a total length of 2124.43 cM with an average distance of 0.25 cM between markers. In this study, 585 QTLs and 191 effective genes related to tolerance to abiotic stresses were identified in MQTLs. The most overlapping QTLs related to tolerance to abiotic stresses were observed in MQTL6.3. Furthermore, three MegaMQTL were identified, which explained more than 30% of the phenotypic variation. MQTLs, candidate genes, and linked molecular markers identified are essential in barley breeding and breeding programs to develop produce cultivars resistant to abiotic stresses.
