“…Root and shoot biomass showed high associations, including the functional SNP in PPD-H1, under osmotic stress and nonstress conditions (Valluru et al, 2017), which demonstrates the effect of HvPPD-H1 on barley root growth as well. Arifuzzaman et al (2017) also found that the head date gene Vrn-H3 is significantly associated with shoot and root biomass; however, no associations were detected close to it in our GWAS panel. Even though the second promising LD block in the present study was indeed detected on the long arm of chromosome 7H, Vrn-H3 was found on the short arm of this chromosome.…”

“…QTLs that determine root fresh weight were previously found on chromosomes 1H, 2H and 5H ( Xu et al., 2012 ; Broughton et al., 2015 ). Regions on chromosome 7H have been primarily identified as associated with root length ( Ain et al., 2015 ; Xue et al., 2017 ), however, associations between the regions on chromosome 7H linked to root biomass have also been reported ( Arifuzzaman et al., 2014 ; Arifuzzaman et al., 2017 ).…”

The root system is a key component for plant survival and productivity. In particular, under stress conditions, developing plants with a better root architecture can ensure productivity. The objectives of this study were to investigate the phenotypic variation of selected root- and yield-related traits in a diverse panel of spring barley genotypes. By performing a genome-wide association study (GWAS), we identified several associations underlying the variations occurring in root- and yield-related traits in response to natural variations in soil moisture. Here, we report the results of the GWAS based on both individual single-nucleotide polymorphism markers and linkage disequilibrium (LD) blocks of markers for 11 phenotypic traits related to plant morphology, grain quality, and root system in a group of spring barley accessions grown under field conditions. We also evaluated the root structure of these accessions by using a nondestructive method based on electrical capacitance. The results showed the importance of two LD-based blocks on chromosomes 2H and 7H in the expression of root architecture and yield-related traits. Our results revealed the importance of the region on the short arm of chromosome 2H in the expression of root- and yield-related traits. This study emphasized the pleiotropic effect of this region with respect to heading time and other important agronomic traits, including root architecture. Furthermore, this investigation provides new insights into the roles played by root traits in the yield performance of barley plants grown under natural conditions with daily variations in soil moisture content.

Heading date (HD) is an important agronomic trait that influences plant adaptability to varying environment and, ultimately, grain yield. In this study, two doubled haploid (DH) populations were used to identify new QTL for HD. One of DH population is originated from a cross between an Australian malting barley cv. Franklin and a wild barley accession TAM407227 and the other one is from the cross between a Syrian wild barley SYR01 and an Australian malting barley cv. Gairdner. Using three times of sowing (TOSs) differing in daylength and temperature, we investigated quantitative trait loci (QTL) controlling HD from both populations. Fourteen QTL were identified for HD from different populations and sowing dates. The expression of HD related genes varied with the TOS, suggesting a significant QTL × environment interaction. By comparing the positions of previously mapped HD genes and those of QTL detected in this population, we found that eleven of the fourteen QTL identified in this study were located at similar positions to those reported genes for HD. Among the three new potential QTL, one was located at 73.5 cM on chromosome 2H, explaining 19.2% and 4.6% HD of DH lines in spring and summer growing, respectively. The wild barley parent TAM407227 contributed the early maturity allele. HORVU2Hr1G088460 within the interval of QTL could be the candidate gene. The second new QTL was identified on chromosome 3H from a summer sowing trial and the third one on chromosome 4H affected HD of DH lines only under spring sowing condition. These new QTL identified will provide an alternative genetic resource for plant breeders developing barley varieties with improved HD adaptability to varying environments.
