Abstract

The spreaging of the arid and semiarid zones due to erratic rainfall and the
progressive heating of the atmosphere has become a major problem for cropping. One of the main measures in order to alleviate the draught in the sustainable agriculture is the identification and using draught resistant genotypes. Thos is why the present paper has studied the behavior of 25 sunflower genotypes at ARDS Şimnic-Craiova in the climatical conditions of 2007 year. The climatical conditions of this year in Oltenia werw extremely dry. As a results of these conditions, the production capacity of researched genotypes has severely decreassed under the real potential, between 850 and 1850 kg/ha. A better doroght tolerance expressed by seed yield was recorder with L 2740, L 625 202, E 627 001 and S861 810. The XR CHMT 0321 and X6 NHW 5353 genotypes have proven the most sensitive to the drought of this year.
