“…The MTAs observed for plant height were all located in chromosomes previously associated with plant height (Liu et al 2011;Zhang et al 2011;Griffiths et al 2012;Zanke et al 2014) however, the specific markers were not identical even though they mapped to the same chromosomal regions. The markers on chromosome 4B (RAC875_c1357_860 and RFL_Contig5341_816), reported by Zanke et al (2014), were located at approximately the same locus (609.0 and 645.3Mb respectively) close to the chromosomal region identified in the present study (506-553Mb) (all chromosomal locations are based on IWGSC blast results).…”

“…In winter wheat, marker-trait associations (MTAs) and genetic markers have been studied intensively for grain yield (Crossa et al 2007;Bordes et al 2014;Ogbonnaya et al 2017;Assanga et al 2017), harvest index (Edae et al 2014;Ain et al 2015;Sukumaran et al 2015;Qaseem et al 2018), plant height (Liu et al 2011;Zhang et al 2011;Griffiths et al 2012;Zanke et al 2014;Bellucci et al 2015), lodging (Verma et al 2005;Zhang et al 2008;Berry and Berry 2015), and STB susceptibility (Brown et al 2015;Arraiano and Brown 2017), while few studies have been undertaken on straw biomass (Sukumaran et al 2015;Qaseem et al 2018) and straw quality (Bellucci et al 2015). It is known that MTAs for grain yield are distributed throughout the genome, as also documented in a study by Crossa et al (2007) in which only chromosome 4D showed no MTAs.…”

Breeding for dual-purpose wheat varieties using marker–trait associations for biomass yield and quality traits

Wheat straw is a valuable feedstock for bioethanol production, but due to the recalcitrant nature of lignocellulose, its efficient use in biorefineries is limited by its low digestibility and difficult conversion of structural carbohydrates into free sugars. A genome-wide association study (GWAS) was conducted to search for significant SNP markers that could be used in a breeding program to improve the value of wheat straw in a biorefinery setting. As part of a three-year breeding program (2015)(2016)(2017), 190 winter wheat lines were phenotyped for traits that affect the yield and quality of the harvested biomass. These traits included straw yield, plant height, lodging at three growth stages, and Septoria tritici blotch (STB) susceptibility. Release of glucose, xylose and arabinose was determined after hydrothermal pretreatment and enzymatic hydrolysis of the straw. The lines were genotyped using 15K SNP markers and 5552 SNP markers could be used after filtering. Heritability for all traits ranged from 0.02 to 0.74. GWASs were conducted using CMLM, SUPER and FarmCPU algorithms, to analyse which algorithm could detect the highest number of marker-trait associations (MTAs). Comparable tendencies were obtained from CMLM and FarmCPU, but FarmCPU produced the most significant results. MTAs were obtained for lodging, harvest index, plant height, STB, glucose, xylose and arabinose at a significance level of p < 9.01 × 10 -6 . MTAs in chromosome 6A were observed for glucose, xylose and arabinose, and could be of importance for increasing sugar release for bioethanol production.

“…The Vrn-A1 locus has been reported to have a reducing effect on plant height, suggesting that Vrn-A1 might be a good candidate gene for these QTL (Kato et al 1999). Additionally, a QTL for plant height on chromosome 6B was detected in a doubled-haploid (DH) population in two different environments (Zhang et al 2011).…”

Drought adversely affects crop growth, development and yield. This study assessed genetic variation in a panel of wheat lines to water deficit and identified the QTLs governing this relationship via GWAS. A panel of 290 lines of the Wheat Association Mapping Initiative (WAMI) population were evaluated under well-irrigated and drought-stressed conditions. Stress tolerance indices were calculated to assess the response of wheat genotypes to water deficit. GWAS was performed using 15,737 SNP markers and six phenotypic traits. Evaluated traits were significantly affected across environments indicating variations in response to drought and ambient conditions. Heritability degrees were moderate to high and ranged from 0.39 to 0.93%. GWAS identified 205 significant marker-trait associations for the six studied phenotypic traits under well-irrigated and drought stress conditions. A positive correlation was found between drought stress index (STI) and plant grain yield (PGY) under both well-irrigated and stressed conditions. A linear relationship between STI and PGY under stressed conditions (PGYs) was observed. STI is the best index for prediction of high yielding genotypes. The WAMI population is a valuable source for improving drought tolerance in wheat. The study revealed significant marker-trait associations with a high degree of genetic diversity underlying different mechanisms for adaptation to drought-prone environments.

“…As well, Wu et al (2010) reported that the plant height of wheat DH lines showed continuous variation and transgressive segregation in different growth stages and environments. Wheat DH populations are an effective material to be used for studying the molecular genetic basis of plant height (Li et al, 2010;Wu et al, 2010;Zhang et al, 2011;Heidari et al, 2012).…”

In wheat, the size of the grain, respectively its dimensions as well as degree of filled, are important characteristics on which depends both the weight of the grain and yield of flour, the quality of milling and baking as well as the production capacity of the respective genotype. This paper presents the results obtained by studying for three years, under field condition, 85 doubled haploid (DH) lines obtained from the F1’s of ‘G.603-86’ (large grains genotype) × ‘F.132’ (normal grains genotype) crosses using biotechnological Zea system. The environmental conditions of the three years had an important contribution on the genotype × year interaction, which showed also a higher influence on 1000 kernel weight (TKW). The variability of plant height and ear emergence data was also affected to a similar extent by this interaction. Based on the performed results and analyses, were highlighted lines which show high and stable values of TKW (54-64 g), associated with a plants height of approximately 85-100 cm and an ear emergence from May 11 to 17, under some climatic conditions similar to the period of study. These doubled haploids lines can be considered as promising genotypes for using in wheat breeding programs in order to improve yield performances under temperate continental climate conditions.
