“…Tsilo et al (2010) also were reported larger heritabilities for kernel morphology and quality traits than grain yield. Huang et al (2006), for TGW and quality traits and Blanco et al (2012), for TGW and quality traits similarly were reported larger heritabilities than grain yield. Russo et al (2014), also observed high heritability for TGW, but they had lower heritabilities for grain size and shape.…”

“…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.…”

“…Russo et al (2014), also observed high heritability for TGW, but they had lower heritabilities for grain size and shape. However, heritability estimates for each trait can be different, depending upon the genetic material, environment and the method of computation (Blanco et al, 2012).…”

“…While, grain shape is generally estimated by length, width, vertical perimeter, sphericity and horizontal axes proportion (Breseghello and Sorrells, 2007). Many studies have been shown that wheat grain size and shape is positively correlated with TGW and they have affected flour yield, end-use quality and market price (Evers et al, 1990;Breseghello and Sorrells, 2006;Tsilo et al, 2010;Cui et al, 2011;Blanco et al, 2012;Williams et al, 2013;Rasheed et al, 2014). Theoretical models predict that milling yield could be increased by optimizing grain size and shape with large and spherical grains being the optimum grain morphology (Evers et al, 1990).…”

“…Although grain yield is one of the major determinants of a farmer's income, quality traits such as GPC is very important for bread-making quality. In more study, grain quality traits such as GPC in wheat have negatively correlated with grain yield and any genetic improvement in GPC has been restricted by the negative correlation between productivity and GPC (Kamra 1971;Bhatia 1975;Loffler and Busch, 1982;Blanco et al, 2012). Although grain yield and GPC are often negatively associated, some researchers reported wheat cultivars with high grain yield and high GPC in bread and durum wheat (Stuber et al, 1962;Johnson et al, 1973;Sears, 1998;De Ambrogio and Ranieri, 2002;Oury et al, 2003;De Ambrogio and Ranieri, 2002;Clarke et al, 2005).…”

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.

Organic transition in dual‐purpose wheat systems: Agronomic performance and soil nitrogen dynamics

et al. 2022

View full text Add to dashboard Cite

The Southern Great Plains (SGP) region of the United States is widely known for its dryland dual-purpose winter wheat (Triticum aestivum L.) cropping systemsintegrated systems that provide both livestock grazing and grain production. Few of these systems are organic, however, and no relevant research had been conducted on this topic. A large-scale (41 ha) systems research study was conducted for 3 yr (2018-2021) to compare a transitional organic dual-purpose wheat system with a conventional one, with system management components customized to the ecological region. Organic wheat yield was 20% lower than conventional in the first season of organic transition, but there was no yield difference by the third year.The yield improvement in the organic system may be attributed to N fixation by a legume-based cash crop the previous winter season, exogenous nutrients from application of composted manure, and appropriate wheat cultivar selection. Because of limited moisture, relying on annual establishment of summer cover crops to fix N and deliver other ecosystem services in the organic system was not feasible in most years. Grain protein concentration (GPC) of the transitional organic wheat ranged from 91 to 103 g kg −1 , below the 120 g kg −1 threshold for a food market organic price premium. More intensive N management, including in-season application of a more available form of N that is organic approved, could be an effective strategy to increase GPC. This proof-of-concept study shows that organic dual-purpose wheat systems can be a viable enterprise in the SGP, though additional research is needed to address challenges identified herein. INTRODUCTIONAmong all grain crops, more acreage of wheat (Triticum aestivum L.) has been produced organically in the United States since 1995 than all other countries (McBride et al.

Concurrent improvement of durum and emmer wheat through reciprocal backcrossing and hybridization

et al. 2022

Emmer wheat has not been improved but is a valuable gene source for improving durum (Triticum turgidum ssp. durum). Conversely, durum is less looked upon for emmer (T. turgidum ssp. dicoccum) improvement. This study examined the possibility of concurrently improving the two species by crossing eight durum cultivars with four emmer local varieties in a half-diallel fashion in two consecutive years. Also, emmer and two durum genotypes were reciprocally backcrossed, and their BC 1 F 1 progeny were field-evaluated during the wheat cropping season (November-June) at the Isfahan University of Technology research farm (32˚32′ N, 51˚23′ E). The results showed that durum wheat had a considerable effect on the grain yield (GY), kernel diameter, 1,000-kernel weight (TKW), and test weight of F 1 hybrids, whereas emmer contributed more to increasing the grain protein content (GPC), kernel length, and plant height (PH). A similar pattern was observed for BC 1 F 1 hybrids from the two recurrent durum parents. The GPC was reduced with recurrent durum parents in the backcrosses compared with emmer, but was still higher than in both durum parents. In the backcrosses with the recurrent emmer parent, GY and TKW were higher than those of emmer but only slightly lower than those of the durum parents. The PH was strongly influenced by emmer in all crosses, though the lodging was significantly reduced compared with emmer, possibly through obtaining stronger stems from durum. These findings suggest the possibility of combining desirable genes from the two species and their concurrent improvement in a single breeding program.
