“…Several studies have shown the considerable variability among the Spanish wheat landraces compared to other germplasm collections [36,37]. These materials can be an important source of genes for wheat improvement, such as rust resistance [38] and quality traits [37,39]. However, even after the removal of redundant accessions, the collection maintained at CRF-INIA comprising more than 500 landraces is too large for evaluation and use in most breeding programs.…”

Modern plant breeding practices have narrowed the genetic base of wheat throughout the world, increasing crop vulnerability. Therefore, there is clearly a need for introducing new germplasm in breeding programs to search for variability related to traits of agronomic interest for wheat improvement. The existence of subsets of accessions (core collections) that represent the diversity conserved in germplasm collections is a favored approach for breeders to explore novel variation and enhance the use of germplasm. In this study, a core collection of Spanish landraces of bread wheat has been created using high-throughput genotyping technologies (DArTseq), which yielded more than 50 K molecular markers. This marker system not only provides a robust estimate of the diversity, but also information about its distribution in the genome. Two core collections of 94 entries were created by using two common sampling strategies: the maximization strategy and the population structure-based method. Both core collections showed high geographic, phenotypic and genetic representativeness, but the collection obtained with the maximization strategy captured better the diversity displayed by the initial collection. This core collection, which includes a broad range of adapted genotypes, can be efficiently utilized for mining new alleles for useful traits in wheat breeding.

Over recent decades, several types of ancient grain varieties have been reintroduced through organic farming systems. In the past 20 years, there has been a renewed interest in growing spelt, and this species has a market niche in Europe and North America in natural, organic and healthy products. Are there any differences between commercial wheat varieties and spelt? The analysis of the bread-making quality of three bread wheat and two spelt cultivars has found no significant differences between the two types of wheat in protein, Fe or Zn, although differences were observed between cultivars. In mean quality parameters, a marked difference was observed between the bread wheat and spelt cultivars, the latter having poorer alveo-consistographic characteristics, indicative of weaker gluten and dough. With the exception of the variety 'Craklin', the gliadin/glutenin (Gli/Glu) ratio is negatively correlated with the technological quality of cultivars. Principal component analysis shows that the two commercial wheats 'Bonpain' and 'Sensas' lying close to gluten strength parameters; and, dough extensibility was associated with total gliadin content and the Gli/Glu ratio, both types of spelt being more closely related to these parameters, indicating that spelts are associated with greater dough extensibility.
