Abstract: Winter wheat cereal crop remains still difficult as it is facing several technical and climatic constraints. All these constraints have a negative influence on yield and on quality of durum wheat in Algeria. In this complicated context, we only can point out priorities that have been identified by agriculture research field, which is naturally seed production of high quality by local varieties. These genotypes will be further of better grain and semoulina level. For this purpose, a trial of a diversified germplasm has been studied. The quality parameters have been essentially qualitative ones (paste and semoulina), by using a small amount of grains (NIRS, non destructive method). The present research will discuss results on high variability which, by the way, seems to be linked to the interaction Genotype- Environment, but also to the genetic potential as well, capable to determine qualitative abilities of the varieties. This method, resolutive and rapid at the same time, may constitute supplementary issue in the selection of quality criteria in wheat.
