Morocco is considered as one of the "hotspots" regions of biodiversity in the Mediterranean basin. It is home to a very diverse flora (4,200 species representing 940 genera and 135 families). For these reasons, Morocco opted for the creation of a central genebank to federate and organize the conservation activities of the important plant genetic re...

Wheat is the major staple food crops of Morocco, Algeria and Tunisia and grown mainly under rainfed conditions. Biotic stresses such as yellow rust, leaf rust and the Hessian fly and abiotic stresses mainly drought constrains for wheat production. As a result, these countries are not self sufficient in wheat production and import wheat most of the...

Genetic characterization, diversity analysis and estimate of the genetic relationship among varieties using functional and random DNA markers linked to agronomic traits can provide relevant guidelines in selecting parents and designing new breeding strategies for marker-assisted wheat cultivar improvement. Here, we characterize 20 Moroccan and 19 e...
Article
Full-text available
It has been argued that genetic diversity in crop varieties has been on the decline in recent times due to plant breeding. This can have serious consequences for both the genetic vulnerability of crops and their plasticity when responding to changes in production environments. It is, therefore, vital for plant breeding programs to maintain sufficie...

Genetic resources harbor natural variation in genes and genotypes associated with traits that are strategically important for adaptation and mitigation to the changes in climate. This study predicts the germplasm accessions that may harbor natural variation of traits related to climate change adaptation. The approach considers a trait as a response...

Wheat production in Morocco is crucial for economy and food security. However, wheat production is difficult because the semi-arid climate causes very variable wheat yields. To solve this issue, we need better prediction of the impact of drought on wheat yields to adapt cropping management to the semi-arid climate. Here, we adapted the models WOFOS...

The conservation and use of plant (animal, aquatic and microbial) genetic resources is multi-disciplinary, multi-stakeholder, multi-level and multi-faceted. Thus, efficient and effective conservation (and use) can not be done in isolation. Through a network approach the necessary strength, knowledge, infrastructure and capacity will be acquired to link the different situations, conditions and resources to allow synergies and additional benefits to be achieved.
