Overview of Identified Genomic Regions Associated with Various Agronomic and Physiological Traits in Barley under Abiotic Stresses

Climate change has caused breeders to focus on varieties that are able grow under unfavorable conditions, such as drought, high and low temperatures, salinity, other stressors. In recent decades, progress in biotechnology its related tools provided opportunities dissect decipher the genetic basis of tolerance various stress conditions. One approach is identification genomic regions linked with specific or multiple characteristics. Cereal crops have a key role supplying energy required for human animal populations. However, crop products dramatically affected by environmental stresses. Barley (Hordeum vulgare L.) one oldest domesticated cultivated globally. Research shown that, compared cereals, barley well adapted harsh There ample literature regarding these responses abiotic stressors, associated morpho-physiological biochemical traits tolerance. This review focuses (i) identifying mechanisms important stable growth development, (ii) applicability QTL mapping association analysis stress-tolerance traits, order help marker-assisted selection (MAS) quickly screen tolerant germplasms their breeding cycles. Overall, information presented here will inform assist future programs.
