The effect of osmotic and water stresses on various morphological traits was studied in eight experimental varieties of sunflower bred for Moroccan conditions or issued from interspecific hybridization with  H.argophyllus  or  H.debilis . Seed yield of the same genotypes was also evaluated under rainfed and irrigated field conditions. Shoot and root growth were significantly reduced by osmotic stress (-0.6 and -1.0 MPa) induced with polyethylene glycol (PEG 6000). Considerable genotype variation was expressed for all traits. Significant genotype by stress interaction was observed for root dry weight and volume as well as seed yield. The morphological traits were not related to seed yield in the correlation and principal component analyses. Four genotypes issued from introgression with  H.argophyllus  were grouped and distinct from other genotypes according to hierarchical ascending classification. One genotype issued from introgression with  H.debilis  and three non-introgressed sunflower varieties were found to be very distinct from each other and from those introgressed with  H.argophyllus .
