This investigation was carried out to determine the adaptability patterns of a set of 30 durum wheat (Triticum durum Desf.) genotypes evaluated across four Algerians locations. The results indicated that yield varied widely within and between locations, and was significantly affected by location, genotype and genotype x location interaction, which accounted for 91.78, 2.06 and 6.24% of the treatment variation. Compared to the joint regression which explained only 10.13%, the AMMI analysis explained 92.65% of the sum square of the interaction and indicated that all locations exhibited high interaction and could be grouped into two recommendation domains: Khroub, Sétif and Tiaret vs Oued Smar. Bichena/Ariza2//Solga8 expressed high yield main effect, high stability, good reliability and large adaptability to all locations, while Gcn/4/D68.1.93A//Ruff /Fg/3/Mtl5 showed specific adaptation to Oued Smar location. These results indicated that breeders had the choice to select Bichena/Ariza2//Solga8 due to its large adaptation and above average grain yield against the alternative to recommend this genotype to the sub region represented by Khroub, Sétif and Tiaret locations and to select Gcn/4/D68.1.93A//Ruff /Fg/3/Mtl5 specifically for Oued Smar location. The strategy associating general adaptation to a large sub region with specific adaptation resulted in 7.16% yield gain.

MNK Publication was founded in 2012 to upholder revolutionary ideas that would advance the research and practice of business and management. Today, we comply with to advance fresh thinking in latest scientific fields where we think we can make a real difference and growth now also including medical and social care, education,management and engineering.
We offers several opportunities for partnership and tie-up with individual, corporate and organizational level. We are working on the open access platform. Editors, authors, readers, librarians and conference organizer can work together. We are giving open opportunities to all. Our team is always willing to work and collaborate to promote open access publication.
Our Journals provide one of the strongest International open access platform for research communities. Our conference proceeding services provide conference organizers a privileged platform for publishing extended conference papers as journal publications. It is deliberated to disseminate scientific research and to establish long term International collaborations and partnerships with academic communities and conference organizers.
