Romania is located at the North limit of rice cultivation area. The rice could be cultivated in a narrow area of 40 km, from Turnu Severin to Braila, as well as in Banat – Banloc. Although is a tropical crop, the rice has a special ecological plasticity, fact that allows the crop extension from equator to the latitude of 48 0 N and from the sea level till 1500-1800 m altitude, in areas with temperatures over 10 0 C at germination and over 15 0 C during vegetation till ripening. In Romania, main important are cultivated genotypes which must reach the maturity till autumn hoarfrosts. Twelve genotypes with variable vegetation period were tested in order to find the most adequate ones from cultivation area Oltenita-Chirnogi.
