Rice, considered as tropical crop, is also cultivated in sub-tropical and continental areas due to its genetic diversity. The main climatic factors which influence this crop are temperature and light. Romania is located at the North limit of rice cultivation area. Rice could be cultivated in a narrow area from Turnu Severin to Braila as well as in South-east of Banat. So, for our country main importance has the sowing time, the vegetation period of new genotypes must allow the maturity stage. During 2003-2005, at Rice Experimental Center Chirnogi, 7 genotypes and 3 sowing times were tested.
