“…(); Mikolajczak et al. (), no QTL for the grain yield per plant identified in the greenhouse (with controlled drought) was found for the grain yield per plot in experiments conducted under field conditions. PH also appeared to be a trait that could not be predicted by observing the stem length in the greenhouse experiments.…”

“…Three of these QTLs, for TGW, were linked to the markers 2822–739, ABC09432‐1‐1‐160 and 4679–1594, and two for LMS‐PH to the markers 10207–1024, 1066–2110. All these markers were found to have stable effects in natural and controlled environments in the mapping populations (Mikolajczak et al., ; Mikołajczak et al., ; Ogrodowicz et al., ). Two varieties with positive alleles in both markers linked to LMS (Gawrosz and Jersey) were very high, whereas varieties having alleles decreasing height were numerous (which reflects the breeding selection process) and were located in the middle of the ranking.…”

“…The size of the drought effects, and thus, the stress tolerance, is genetically controlled (Anjum et al., ; Bandurska et al., ; Blum, ; Chmielewska et al., ; Daszkowska‐Golec & Szarejko, ; De Mezer et al., ; Filek et al., ; Forster et al., ; Jozefaciuk & Lukowska, ; Piasecka et al., ).

Genetic maps well‐saturated with molecular markers, used in these studies, have enabled the localization of quantitative trait loci (QTLs) with stable effects on the yield and the related traits under optimal and drought conditions, and the distinguishing of markers useful in the selection of genotypes more tolerant to drought.…”

The yield potential of 60 spring barley varieties was examined under controlled drought and natural conditions in the years 2011–2013. The studied varieties were genotyped with the 1536‐SNP barley oligonucleotide assay. In experiments with controlled drought conditions, the grain yield, 1,000‐grain weight, number of productive tillers and length of the main stem were measured. Physicochemical properties such as the specific surface area, water adsorption energy, fractal dimension and nanopore radius of the plant leaves were determined and correlated with yield‐forming traits. Field trials were conducted over 3 years at 14 locations, where along with the yield‐related traits, monthly rainfall and average temperature were monitored. Five varieties of high yield and five varieties relatively stable under both semi‐controlled and natural conditions were distinguished. The yield‐related traits observed in various locations were related to environmental variables relevant to water availability. The sum of the rainfall in April and May was negatively correlated with the 1,000‐grain weight and positively with the plant height. Positive relationships were found between plant height and temperatures in June and July. Five markers detected earlier as linked to the quantitative trait loci in the mapping populations were identified to have a coherent effect among varieties of various pedigree.

A recombinant inbred line mapping population was developed from a cross between the heritage malting barley (Hordeum vulgare ssp. vulgare) cultivar ‘Golden Promise’ and ‘Otis’, a feed barley cultivar developed in the 1960s suitable for the high dry plains. The Golden Promise/Otis recombinant inbred line (RIL) population (MP‐3, NSL 545640 MAP) consists of 190 F5:7 individuals. The parental lines exhibited significant differences in several agronomic traits including height, heading date, yield/plant, and lodging. Transgressive segregation in the RILs was evidenced by the broad range of values observed for these agronomic traits. The RIL population was genotyped using the Illumina 50k iSelect single nucleotide polymorphism (SNP) arrays. Of the 10,810 polymorphic markers that were identified between the two parents, 4617 markers were used for generating a genetic map that spanned 4566 cM with an average distance of 1 cM between markers. The fact that Golden Promise is a malting cultivar developed in the United Kingdom, versus Otis, a feed barley bred in the United States for dryland cultivation, indicates that this population may be useful in identifying the genetic basis of many other traits.

Barley is a resilient crop plant with higher tolerance than other cereal plants for several types of abiotic stress. In this chapter, we describe the genetic components underlying barley's response to abiotic stresses, including soil acidity, boron toxicity, soil salinity, drought, temperature, and nutrient deficiency. We describe typical symptoms observed in barley in response to these stresses. We enumerate the major qualitative trait loci (QTLs) identified so far, such as FR-H1 and FR-H2 for low-temperature tolerance. We also discuss candidate genes that are the basis for stress tolerance, such as HVP10, which underlies the HvNax3 locus for salinity tolerance. Although knowledge about barley's responses to abiotic stresses is far from complete, the genetic diversity in cultivated barley and its close wild relatives could be further exploited to improve stress tolerance. To this end, the release of the barley high-quality reference genome provides a powerful tool to facilitate identification of new genes underlying barley's relatively high tolerance to several abiotic stresses. Early research on the genetic control of Al tolerance in barley using the Dayton (Al-tolerant) and Smooth Awn 86 (Al-sensitive) genotypes detected a major locus, Alp, on the long arm of chromosome 4H (4HL) (Minella and Sorrells 1992; Reid 1971). Another early study found that a single gene, named Pht, on
