The present study was undertaken to evaluate some important agronomic traits (yield, thousand seed weight, plant height, oil content and fatty acid composition) and crossability of B. carinata and B. napus in a greenhouse. Remarkable changes in oleic (32.49%) and erucic acid (20%) concentrations were recorded in crosses of DH BC Dodolla with DH BN SL-730. The combining ability of several DH lines of BC resulted in a heterosis effect. Hybrids between DH lines of BC 6 and the DH line BC Dodolla showed intermediate height to that of their parents. The DH line Dodolla proved to be the most productive DH regenerant in our experiments. Therefore, the use of B. carinata in interspecific and intraspecific hybridization may be very useful.
