Alloplasmic Brassica juncea was synthesized by repeatedly backcrossing amphidiploid of Erucastrum gallicum × B. juncea with pollen of B. juncea. The E. gallicum cytoplasm was also transferred to B. napus and B. carinata through alloplasmic (E. gallicum) B. juncea. RFLP analyses of organelle DNA confirmed the presence of E. gallicum cytoplasm in all the alloplasmics. The cytoplasm of E. gallicum, though alien, did not induce stable cytoplasmic male sterility in any of the oilseed brassicas. Many useful variants such as early flowering and dwarf phenotypes were isolated in the alloplasmics of B. napus and B. carinata. These morphotypes provide useful genetic variability for the improvement of crop brassicas.
