“…For example, two genotype 97 and 42 with 9.64 and 7.58 length, and with 3.43 and 4.53 width can used as parents to create segregation populations for quantitative trait loci (QTL) studies. Despite the high variety and acceptable quality of Iranian bread wheat landraces, it seems these genotypes had lower quality compared with some bread populations in Blanco et al (2012) and Kalous et al (2015) studies.…”

Grain characteristics, particularly grain weight, grain morphology, and grain protein content (GPC), are important components of grain yield and quality in wheat. A set of 98 bread wheat landraces from different geographic regions of Iran were used across 2013-2014 and 2014-2015 to determine the phenotypic diversity and relations between thousand grain weight (TGW), grain morphology and grain quality. A high-throughput method was used to capture grain size and shape. The genotypes were significantly different (P < 0.001) for all traits which reflects the high levels of diversity. A moderate to high broad sense heritability was found for all traits and ranged between 0.68 and 0.95 for grain yield and factor from density (FFD), respectively. Significant positive correlations were observed between TGW and grain size (or shape) exception of aspect ratio (AR) and roundness. However, grain quality traits, especially GPC had significant negative correlation with TGW. Based on stepwise regression analysis by taking TGW as dependent variable, grain volume, FFD, width, perimeter and Hardness Index (HI) were recognized as the most important traits and explained more than 99.3% of total variation of TGW. The path analysis revealed that FFD has maximum direct effect on TGW followed by volume, whereas perimeter and width had relatively less direct effect on TGW. According to cluster analysis, landraces separated into 5 clusters, and cluster III and IV had the maximum and minimum average for the most traits, respectively. Our study provides new knowledge on the relations between TGW, grain morphology and grain quality in bread wheat, which may aid the improvement of wheat grain weight trait in further research.

“…The number of D-genome chromosomes retained was determined using cytological characterisation (Kihara, 1982; Wang et al, 2005; Eberhard et al, 2010), or molecular markers (Lanning et al, 2008; Eberhard et al, 2010; Martin et al, 2011; Kalous et al, 2015). Molecular marker data indicates the presence or absence of unique chromosomes, but fails to determine the number of copies of unique chromosomes.…”

“…The resultant interspecific lines showed improved bread loaf volume (cm 3 ), ranging from 295 to 442.5, when compared to the tester bread wheat lines, which ranged from 390.0 to 437.5. Interspecific hybridisation involving hexaploid/tetraploid crosses has demonstrated that the resultant progeny have significantly improved grain weight, grain diameter, and grain yield (Kalous et al, 2015). Furthermore, it was suggested that introducing 1D chromosome segments and their associated protein products would improve the bread making quality of durum wheat (Sissons, 2008).…”

“…Hybridisation between these two species with different ploidy levels leads to a pentaploid hybrid (AABBD) that has the chromosomal constitution of 2n = 5x = 35 (Kihara, 1924). The genetic variability that is combined from hexaploid and tetraploid wheat into a pentaploid hybrid has great potential in crop improvement (Eberhard et al, 2010; Martin et al, 2013; Kalous et al, 2015). However, while several reviews have focussed on the successful establishment of interspecific wheat hybrids (Sharma and Gill, 1983; Jiang et al, 1993; Friebe et al, 1996), little emphasis has been placed on developing efficient methods to incorporate these pentaploid hybrids into commercial breeding practices.…”

“…Developing wheat hybrids through alien introgression is highly challenging when compared to hybridisation between domesticated inter-ploidy species such as bread and durum wheat. Recently, there has been a renewed interest in developing hexaploid/tetraploid wheat crosses to improve elite bread and durum wheat lines for a number of economically desirable characters (Martin et al, 2011, 2013; Han et al, 2014, 2016; Kalous et al, 2015). …”

Interspecific hybridisation between hexaploid and tetraploid wheat species leads to the development of F1 pentaploid hybrids with unique chromosomal constitutions. Pentaploid hybrids derived from bread wheat (Triticum aestivum L.) and durum wheat (Triticum turgidum spp. durum Desf.) crosses can improve the genetic background of either parent by transferring traits of interest. The genetic variability derived from bread and durum wheat and transferred into pentaploid hybrids has the potential to improve disease resistance, abiotic tolerance, and grain quality, and to enhance agronomic characters. Nonetheless, pentaploid wheat hybrids have not been fully exploited in breeding programs aimed at improving crops. There are several potential barriers for efficient pentaploid wheat production, such as low pollen compatibility, poor seed set, failed seedling establishment, and frequent sterility in F1 hybrids. However, most of the barriers can be overcome by careful selection of the parental genotypes and by employing the higher ploidy level genotype as the maternal parent. In this review, we summarize the current research on pentaploid wheat hybrids and analyze the advantages and pitfalls of current methods used to assess pentaploid-derived lines. Furthermore, we discuss current and potential applications in commercial breeding programs and future directions for research into pentaploid wheat.

Background and objectives Hard red spring wheat (Triticum aestivum L.) (HRSW) is used for bread baking while durum wheat (Triticum turgidum L. ssp. durum) is used for pasta production. This study investigated the impact of alleles from durum wheat for yield component traits on HRSW end‐use quality traits. Near‐isogenic lines for four quantitative trait loci, QGw.mst‐3B, QGw.mst‐7A, QTn.mst‐5B, and QYld.mst‐2B, were evaluated in rainfed and irrigated environments. Findings Durum alleles were found to significantly impact end‐use quality at all four loci. The durum allele QGw.mst‐3B for increased kernel weight (KWT) positively impacted end‐use quality traits with increases in kernel protein and loaf volume. The durum allele at QTn.mst‐5B delayed heading date, impacting productive tiller number and KWT and additional end‐use quality traits. The durum allele at QYld.mst‐2B for GY showed both positive and negative effects on end‐use quality. The durum allele for reduced spikelet number per spike at QGw.mst‐7A had little to no impact on end‐use quality. Conclusions Results from the present study indicate that the alleles from durum wheat are potential sources of cultivar improvement; however, interactions between yield component and end‐use quality traits may influence utilization. Significance and novelty This study demonstrates the potential utility of introgressed durum yield component alleles for genetic improvement in HRSW.
