“…The mixograph measures the resistance of a dough against to rotating pins and is commonly used to estimate end-use quality of flours from wheat breeding programs (Guzman, Mondal, et al, 2016;Şahin, Akçacık, Aydoğan, Taner, & Ayrancı, 2011;Shen et al, 2010;Hernandes-Espinosa et al, 2018). Among the measured mixograph parameters, peak weight (PW) and area (T INT) values are often used as a good indicator of gluten strength.…”

Background and objectives The gluten strength of soft wheat breeding materials can be categorized according to various quality tests. While weak gluten in flours is typically required for the production of soft‐dough biscuits, extensible dough with medium gluten strength is required from flours suitable for the production of other types of biscuits. Genotypes that have high gluten strength are ordinarily eliminated from soft wheat breeding programs. Therefore, small‐scale quality test methods that can predict the gluten strength of genotypes, especially in the early stages of breeding, are highly desirable. In the present study, the effectiveness and efficiency of a small‐scale lactic acid solvent retention capacity (LASRC) test, as a potential simplified means to evaluate gluten strength for soft wheat breeding programs, were investigated. Findings Soft wheat genotypes grown in different locations were categorized by the LASRC values of their flours. GlutoPeak, Mixolab, farinograph, mixograph, Zeleny sedimentation, and glutenin swelling index test results were also used for comparison, in order to assess the effectiveness and efficiency of LASRC. LASRC test results successfully discriminated between soft‐/weak‐ and hard‐/strong‐dough groups, but were sometimes less successful in discriminating between hard‐/strong‐ and medium‐strong‐dough groups. Mixograph development time and area, farinograph stability and degree of softening, Mixolab stability, GlutoPeak AM value, and Zeleny sedimentation parameters all showed strong correlations with LASRC. Conclusions This study confirmed that new a small‐scale LASRC has potential as a simplified, rapid, and effective small‐sample test. Significance and novelty This LASRC small‐sample flour test can be recommended for predicting gluten strength, especially for early‐generation selection of soft wheat breeding materials.

“…Grain quality is subject to genotype-by-environment (G × E) interaction necessitating selection of promising genotypes to develop market-preferred varieties (Flagella et al 2010;Malik et al 2013;Rozbicki et al 2015;Migliorini et al 2016;Hernández-Espinosa et al 2018). G × E interaction refers to differences in genotypic performance for test traits across diverse environments (Yan and Kang 2003).…”

“…This may limit effective selection of ideal genotypes possessing useful attributes for grain quality improvement. Wheat is cultivated in arid and semi-arid environments where recurrent drought spells and heat stress affect nutritional and processing quality (De Vita et al 2007;Li et al 2013;Hernández-Espinosa et al 2018). Currently, low genetic gains are reported for grain protein content and protein-fractions (Subira et al 2014;Sanchez-Garcia et al 2015).…”

This study determined genotype-by-environment effect on grain quality among heat and drought tolerant bread wheat genotypes to select ideal genotypes for grain quality improvement. Gliadin (Gli), gluten (Glu), glutenin (Glut), gliadin: glutenin ratio (Gli: Glut ratio) and total protein content (TPC) were determined among 28 elite bread wheat genotypes under non-stressed and droughtstressed conditions. Additive main effect and multiplicative interaction and genotype and genotype-by-environment biplot were used for data analyses. Large genotypic effects were observed for Gli (55.42%), TPC (67.78%) and Gli: Glu ratio (49.77%), suggesting genotypic variation for these traits. High environmental influence of 89.65 and 89.06% were observed for Glu and Glut. Wheat genotypes LM03, LM22, LM23, LM41, LM44, LM60, LM62, LM71, LM73, LM71, LM85, LM90 and LM95 with high protein and protein-fractions and high levels of abiotic stress tolerance (i.e. heat and drought) were selected for breeding for high grain quality.

“…As a result, shuttle breeding can be used to develop drought tolerant, early-maturing groundnut varieties with high-yield, good seed quality, diseases and insect pest resistance and wide adaptability. In wheat (Triticum aestivum L.) shuttle breeding has been employed by the International Maize and Wheat Improvement Centre (CIMMYT) to develop wheat genotypes possessing biotic and abiotic stress tolerance, high-yield potential and good enduser quality attributes for cultivation across diverse environments (Crespo-Herrera et al 2018;Hernández-Espinosa et al 2018). This is achieved through the introduction of new and novel sources of genetic variation from wild species, landraces, and other sources of useful alleles (i.e.…”

Groundnut (Arachis hypogaea L.) is a multipurpose legume crop widely cultivated in sub-Saharan Africa (SSA). However, yield levels of the crop has remained relatively low in SSA owing to a range of biotic, abiotic and socioeconomic constraints. A dedicated groundnut improvement programme integrating new tools and methodologies to breed varieties suitable for current and emerging agro-ecologies and market needs is essential for enhanced and sustainable groundnut production in SSA. The objective of this review is to highlight breeding progress, opportunities and challenges on groundnut improvement with regard to cultivar development and deployment in SSA in order to guide future improvement of the crop. The review analysed the role of new tools in breeding such as, high-throughput and automated phenotyping techniques, rapid generation advancement, single seed descent approach, marker-assisted selection, genomic selection, next-generation sequencing, genetic engineering and genome editing for accelerated breeding and cultivar development of groundnut.
