“…In the present work, differences among the lines in IVOMD were below 3 percentage points (Table 1, Table 3). These findings agree with observations by Joshi et al (2019) and Blümmel et al (2019a) from comprehensive overviews of wheat straw breeding work in South Asia who reported very limited genetic variation in wheat straw fodder quality.…”

HighlightsA wheat population of 287 diverse spring wheat lines were evaluated in a multilocation trial.Genome-wide association studies (GWAS) were applied to detect significant marker- straw fodder quality trait associations.Five genomic regions contributed for six traits (ADF, ADL, ASH, IVOMD, ME and NDF).ADF and ADL mapped in the common QTL region on chromosome 2B. Similarly, for the IVOMD and ME, QTLs were found on chromosome 5B.Strong genotypic variations of GY and SY do exist. The lack of any similar variations in straw fodder quality traits is intriguing and requires further research.

“…We studied 36 genotypes with contrasting GY that included old and modern cultivars bearing germplasm of 3 different origins (CIMMYT, Criollo and French). In agreement with previous reports, we found high variability in all agronomic traits (GY, SY, HI, and ∆LS) [ 35 , 38 , 50 , 51 ]. When all genotypes were regarded together, we found a positive correlation between GY and SY, in agreement with other authors [ 52 ], which suggests that it is possible to increase SY without compromising GY, a central issue for developing DP cultivars [ 14 ].…”

“…With the development of 2G-biofuel production, efforts on increasing the yield and quality of straw to maximize the overall value of wheat crop are expected to increase [ 35 , 68 ]. An analysis run on GY and HI from many trials in the United States allowed to detect differences in SY among wheat classes [ 33 ] and, here, we report genotype effects on both SY and composition, in agreement with previous reports [ 35 , 38 , 69 ]. However, to assess the overall potential of biogas production, both SY and its digestibility must be considered.…”

“…However, despite this positive correlation, high variability of SY can still be found in groups of similar GY (Table 1 , [ 35 ]). These discrepancies regarding SY and GY correlation point out the importance of gaining knowledge on biomass production and allocation in wheat plants [ 38 ].…”

“…One of the most frequently used approaches to assess SY is based on empirical models that infer SY from GY statistics [ 36 ]. However, the uncertainties related to varietal differences in biomass partitioning and its complex response to different environmental and management factors [ 37 ] are difficult to address and, therefore, it becomes necessary to record SY in dedicated field trials [ 36 , 38 ].…”

Background Wheat straw, one of the most abundant agricultural residues worldwide, can be used to produce biogas, which is considered one of the most efficiently produced renewable energies. Wheat grown with the dual-purpose of producing food and biogas should display simultaneously high grain and straw yields, low lodging susceptibility and high conversion efficiency of straw into biogas. The aims of this study were to determine the best food-fuel dual-purpose wheat candidates among 36 wheat genotypes—including French, CIMMYT and local (Criollo) germplasm—used in breeding programs in Argentina and to gain some insights into the relationships between key traits relevant for dual-purpose wheat genotypes. Results High variability in individual key traits for dual-purpose wheat ideotype has been found. Genotypes of French origin displayed the highest grain yield, and those of CIMMYT origin, the lowest straw yield. Genotypes of Criollo origin showed the highest lodging susceptibility, and French ones, the lowest. Straw yield was positively correlated with grain yield in all genotypes, and negatively correlated with plant height in genotypes of Criollo origin. Straw conversion into biogas was measured in terms of the biogas potential production and kinetic parameters Bmax (maximum specific biogas production) and k (first-order kinetic constant) were analyzed. All key traits were analyzed together by a principal component analysis. Baguette 31 and SNR Nogal, two genotypes of French origin, showed high grain yield, high-to-very high straw yield, low lodging susceptibility, and moderate-to-high Bmax and k. Buck Guapo and Buck Baqueano, two genotypes of Criollo origin, displayed good values for grain yield, straw yield and Bmax and k. However, their high lodging susceptibility precludes their production in shallow soils or high-input systems. Lastly, some old genotypes (e.g. Klein Atlas) harbored a good combination of all key traits and could prove valuable to be included in future breeding programs for dual-purpose wheat. Conclusions While none of the genotypes excelled in every key trait, a few candidates showed potential for dual-purpose ideotype, particularly Baguette 31 and SNR Nogal. The challenge lays in gathering all attributes for food and 2G fuel in the same genotype.
