“…On the contrary, grain yield per hectare had highly significant and and positive correlation with thousand grain weight and significant positive correlation with spike length and non-significant positive correlation with peduncle length, plant height and biological yield. This is supported by similar findings from Chaudhary, (1977), Solanki and Bakshi (1973), Gonzalez et al (1999), Bhutta et al (1991), Zadeh et al (2010), Chutimanitsakun et al (2011) and Dahleen et al (2012). Although there exists positive relationship between yield and the other components, the negative correlation between some of them cannot make a useful choice for all as a factor in increasing the yield (Danyard and Kannenberg, 1976).…”

Barley, being a tremendous opportunities crop, we are far back regarding study, research and utilization. An experiment was conducted 2014-2015 to evaluate the barley genotypes for their yield attributing traits and correlation and causation. Eleven yield contributing traits viz., days to booting, heading and flowering; peduncle length, spike length, plant height, flag leaf area, flag leaf-1 area, thousand grain weight, biological weight and yield per hectare were recorded. High significant variation among genotypes was found for traits under study. Genotypes SBYT3-13#1115 (1960 kg), 14-SB-NAK-MR#17 (1760 kg) and AM POP#26 (1660 kg) were found to be superior for their per se performance based on grain yield per hectare, yield attributing and other quantitative traits. Thousand grains weight (0.333) had positively highest significant correlation with grain yield per hectare followed by spike length (0.310). Grain yield per hectare showed negative highly significant correlation with days to flowering (-0.796) followed by days to heading (-0.761) and days to booting (-0.663). Peduncle length (0.229), plant height (0.226), biological weight (0.181) and flag leaf area (0.032) were positively correlated with grain yield per hectare while flag leaf-1 area(-0.029) was negatively correlated. Thus, selection for genotypes with higher thousand grain weight and spike length accommodating earlier days to flowering, heading and booting is a prerequisite for attaining improvement in grain yield per hectare.

“…Quantitative trait loci (QTLs) have been identified for quantitative disease resistance in wheat and barley [4]. Furthermore, resistance to both FHB and DON levels have been mapped to all seven barley chromosomes [29,30], and the most common regions related to FHB resistance have been previously reported to be located on chromosomes 2H and 6H [3,25,31]. Other traits, including awned/awnless ears [26] and spike compactness [32], have also been studied.…”

Mapping of quantitative trait loci for traits linked to fusarium head blight in barley

Fusarium head blight (FHB) is a devastating disease occurring in small grain cereals worldwide. The disease results in the reduction of grain yield, and mycotoxins accumulated in grain are also harmful to both humans and animals. It has been reported that response to pathogen infection may be associated with the morphological and developmental traits of the host plant, e.g. earliness and plant height. Despite many studies, effective markers for selection of barley genotypes with increased resistance to FHB have not been developed. In the present study, we investigated 100 recombinant inbred lines (RIL) of spring barley. Plants were examined in field conditions (three locations) in a completely randomized design with three replications. Barley genotypes were artificially infected with spores of Fusarium culmorum before heading. Apart from the main phenotypic traits (plant height, spike characteristic, grain yield), infected kernels were visually scored and the content of deoxynivalenol (DON) mycotoxin was investigated. A set of 70 Quantitative Trait Loci (QTLs) were detected through phenotyping of the mapping population in field conditions and genotyping using a barley Ilumina 9K iSelect platform. Six loci were detected for the FHB index on chromosomes 2H, 3H, 5H, and 7H. A region on the short arm of chromosome 2H was detected in which many QTLs associated with FHB-and yield-related traits were found. This study confirms that agromorphological traits are tightly related to FHB and should be taken into consideration when breeding barley plants for FHB resistance.

“…So far, no major resistance gene against FHB has been reported. Numerous biparental mapping studies identified minor‐effect QTL that act additively to confer resistance to FHB (de la Pena et al, 1999; Zhu et al, 1999; Ma et al, 2000; Dahleen et al, 2003; Mesfin et al, 2003; Canci et al, 2004; Hori et al, 2005, 2006; Horsley et al, 2006; Sato et al, 2008; Lamb et al, 2009; Yu et al, 2010; Dahleen et al, 2012). These studies have described QTL for FHB resistance, DON accumulation, and kernel discoloration across all seven barley chromosomes (Kolb et al, 2001; Massman et al, 2011); however, the most important regions for FHB resistance lie on chromosomes 2H, 4H, and 6H.…”

“…Several of the FHB resistance QTL identified in biparental studies coincide with QTL for low DON concentration (e.g., Dahleen et al, 2003; Mesfin et al, 2003). Moreover, QTL for low FHB severity and reduced DON concentration are often associated with genes or QTL for various agromorphological traits, including the spike‐type locus Vrs1 , heading date, and plant height (de la Pena et al, 1999; Zhu et al, 1999; Ma et al, 2000; Dahleen et al, 2003, 2012; Mesfin et al, 2003; Hori et al, 2005; Horsley et al, 2006; Lamb et al, 2009). The only resistance QTL reported to be independent of these agronomic traits is the one on chromosome 2HL in PI 643302 (Yu et al, 2010).…”

Fusarium head blight (FHB), caused primarily by Fusarium graminearum, is an important disease of barley (Hordeum vulgare L.), and other cereals. In barley, the genetic basis of FHB resistance has been intensively studied through linkage mapping that identified several quantitative trait loci (QTL). However, our understanding and application of these QTL in breeding is still limited due to the complex nature and low‐to‐moderate heritability of FHB resistance. Previous studies used either breeding lines, unimproved varieties, or germplasm selections. Here, we used association mapping in barley landraces to identify QTL associated with FHB severity, deoxynivalenol (DON) concentration and correlated agromorphological traits. Diverse barley landraces (n = 298) from Ethiopia and Eritrea were evaluated for the traits under field conditions for 2 yr (2011–2012) in Crookston, MN, and genotyped with 7842 single nucleotide polymorphism (SNP) markers. Association mapping analysis using a mixed model corrected for pairwise relatedness between individuals identified one common resistance QTL on barley chromosome 2HL significantly associated with both FHB severity and DON concentration and another one on 4HL associated with DON concentration. The QTL identified on 2HL is associated with the row‐type locus Vrs1. Both of these QTL were not significantly associated with heading date or plant height unlike other QTL reported in previous studies. Thus, the resistant accessions carrying these QTL may be used in breeding programs without the confounding effects from these agromorphological traits. Importantly, these QTL could be new alleles preserved in this unique germplasm, and the linked SNP markers found may be useful in marker‐assisted introgression of resistance.
