Intergeneric hybrid plants were obtained by the sexual crossing of <i>Diplotaxis</i> <i>muralis</i> DC, a C<sub>3</sub> species, and <i>Moricandia arvensis</i> (L.) DC, a C<sub>3</sub>-C<sub>4</sub> intermediate species. The morphological characteristics and chromosome numbers showed that these plants were true hybrids. The hybrid had a CO<sub>2</sub> compensation point of 27 μl/ L, nearly as low as that of <i>M. arvensis</i> (20 μl/L). A C<sub>3</sub>-like value of 45 μl/L for this point was found in somatic hybrids produced in our laboratory by protoplast fusion between red cabbage (<i>Brassica oleracea</i> L. var. <i>capitata</i>) or cauliflower (<i>Brassica</i> <i>oleracea</i> L. var. <i>botrytis</i>) and <i>M. arvensis.</i> However, significant differences were not found among the sexual and the somatic hybrids in the concentration or total activity of ribulose-l,5-bisphosphate carboxylase/oxygenase. The results showed that the expression, of a C<sub>3</sub>-C<sub>4</sub> intermediate character of photosynthesis from <i>M. arvensis</i> appears to depend on the combination of other characters of the parental species.<br>
