Sunflower was suggested as one of the new cash crops in the Gash delta. This study was intended to evaluate adaptability of the crop through the performance of some hybrids and open-pollinated (OP) cultivars under the flood irrigation system of the Gash delta. A set of cultivars were tested in four locations of different irrigation levels of 7-30 days flood periods, and varying soils of silty, clay loam during the seasons 1989-90 and 1990-91. The hybrid Hysun 33 and the two open pollinated (OP) cultivars Rodio (Damazin 1) and Egnazai were considerd as standard cultivars and hence evaluated for the crop performance. Results have shown that Hysun 33 produced a higher yield of 2220, while Rodio and Egnazia recorded lower yields of 1900 and 1760 kg/ha, recpectively. The yields recorded at the Gash delta were higher than the yields of the same cultivars reported from all other locations in Sudan. Rodio recorded a high oil content of 48% in Gash delt a which was higher than the 45% of the Rodio when grown under rain only or supplementary irrigation. The crop did not require chemical pest control in all test locations. Hence, sunflower may be recommended as one of the new cash crops for the Gash delta crop rotation to be planted as a late flood crop
