“…These results are in line with those reported by González et al (2014), who tested a set of Argentinean high-yielding cultivars. Our results are in disagreement with Ferrante et al (2012) and Terrile et al (2017), but these studies had low genetic diversity with only four and two cultivars, respectively. The lack of negative association between FE and TKW found in our study supports the idea that there is not a competitive partial compensation (trade-off ) between them and offers evidence that improving FE can be done without altering TKW.…”

“…This agreed with the earlier study performed by Neumann et al (2011), who reported wide phenotypic variation in this wheat panel for several agronomic traits in a different environment. Particularly, FE showed a range of variation greater than the ones recently reported (Lázaro and Abbate, 2012;González et al, 2014;Gonzalez-Navarro et al, 2016;Terrile et al, 2017). Interestingly, the yield-related traits not only exhibited large variation across all experiments and locations but also displayed that genetic effect was consistently larger than genotype ´ environment interaction, resulting in moderate to high heritability levels.…”

To meet the estimated future increase in wheat (Triticum aestivum L.) demand, exploring and dissecting the genetic basis of yield‐related traits play a crucial role in wheat yield improvement. In this study, we evaluated 12 grain yield‐related traits including fruiting efficiency (FE) in a wheat panel through genome‐wide association mapping (GWAS) approach. The panel displayed large phenotypic variation for all the measured traits, FE was positively associated with grain number per spike but not related to thousand kernel weight. Interestingly, FE was mostly explained by grain number per fertile spikelet (GFS), whereas the latter was determined by spikelet weight (SW). The GWAS identified 44 significant marker‐trait associations (MTAs) across almost the entire wheat genome linked to the 12 yield‐related traits, including four MTAs on chromosomes 2A, 2D, 4D, and 5A associated with FE. Several significant markers were identified in genomic regions previously reported, whereas others appeared to be potentially novel loci. Particularly, the co‐location of significant markers for yield‐related traits with major genes underlying plant development showed pleiotropic effects and the key role of these genes in modulating agronomic traits. The markers linked to FE, GFS, and SW are promising, especially considering that due to the destructive phenotypic determination, their improvement in early breeding generations can only be made by marker‐assisted selection. Taken together, these findings are encouraging and suggest the potential value of FE and associated traits as possible selection criteria to increase yield potential in wheat breeding programs.

“…The same authors suggest that this growth period is not relevant for total biomass production at anthesis, but is crucial for determining the relative grain number. In line with this, Terrile et al (2017) proportional to the availability of assimilates allocated for their development during spike growth before anthesis (Ferrante et al, 2013;González et al, 2011;Slafer et al, 2015). In R23+ plants, the number of fertile florets at anthesis (mirroring the FPF) showed to be similar to its R23-control (Kuzmanovic et al, 2016), while the number of seeds at maturity was enhanced, as a consequence of higher FPS (Table 4 and Supplementary Table 3; see also Kuzmanovic et al, 2014Kuzmanovic et al, , 2016.…”

Introgressions of Thinopyrum ponticum 7AgL chromosome segments spanning 23%, 28% and 40% of the distal end of durum wheat 7AL arm were previously shown to contain multiple beneficial gene(s)/QTL for yield-related traits. In the present study, durum wheat near isogenic recombinant lines (NIRLs) harbouring each of the three introgressions, were included for the first time in multilocation field trials, to evaluate general and environment-specific effects of the alien chromatin on 25 yield-related traits. The results from 11 different trials across contrasting environments of three countries and five years revealed that the presence of 7AgL chromatin had the strongest positive effect on spike (+11%) and grain number (+9%) m -2 , which represented the main contributors to the observed increases in grain yield and biomass (2-6%). In particular, grain yield was significantly increased (+18%) in 7AgL-carrier NIRLs in the water-limited South Australian environment. NIRLs carrying 23% and 28% 7AgL (named R5 and R112, respectively) displayed 2-30% higher grain yield with respect to the site's mean in most of the tested environments. Thus, also for other positive 7AgL genes they carry (Lr19, Sr25, Yp), they could be readily moved into site-directed breeding pipelines.Across all environments evaluated, the NIRL with a 40%-long 7AgL segment (named R23) resulted in increasing effects on grain number m -2 and spike -1 (averaging 47% and 14%, respectively) when compared with its control (no-7AgL). From comparison with the other NIRLs, this major gene/QTL can be located within the most proximal 28-40% 7AgL region, exclusive to the R23 recombinant. 2 The present study represents an important validation of the use of chromosomally engineered genetic stocks for targeted durum wheat improvement.

“…Hence genetic variation in sensitivity of plant physiological processes including photosynthesis to drought is critical to develop climate-resilient crops. Such scientific leads can be translated into physiological traits for indirect selection that can assist to increase wheat yield potential under abiotic stress (Terrile et al 2017). Successful introgression of identified novel traits could be economic and cost effective approach to develop abiotic stress-tolerant germplasm (Varshney et al 2018).…”

In dryland regions, soil moisture stress often leads to desiccation and causes injury to photosynthetic machinery. Recently, chlorophyll fluorescence (ChlF)-based assessment of photosynthetic efficiency under drought stress is gaining attention due to advances in instrument development and methodology optimisation. Our study was designed to explore the use of spike photosynthetic efficiency as a trait to differentiate drought responses in wheat. Bread and durum wheat were assessed for spike, stem, and leaf tissue photosynthetic efficiency in response to progressive desiccation using ChlF imaging. Results showed that durum wheat had higher quantum efficiency and lower photoinhibition of PSII relative to bread wheat across spike, stem, and leaf. Rate of decline in maximum photochemical efficiency of PSII with increased desiccation was seen higher in bread wheat spikes as compared to durum wheat. Our investigation clearly demonstrated that ChlF imaging could be effectively deployed as phenotyping tool to differentiate wheat genotypes for their photosynthetic performance under desiccation.
