Abstract
The present study was undertaken to evaluate some important agronomic traits (yield, 1000 seed weight, plant
height, oil content and fatty acid composition) and crossability of B. carinata and B. napus in the green house. Remarkable
changes in oil (32.49%) and erucic acid (20%) content were recorded in crossing of DH BC Dodolla with
DH BN SL-730. Satisfactory combining ability of several DH lines of BC resulted in heterosis effect in obtained
hybrids. Hybrids between DH lines of BC 6 with DH line BC Dodolla showed intermediate height of their parents.
The DH line Dodolla proved to be the most productive DH regenerant in our experiments. Therefore interspecific
and intraspecific hybridization in Brassicas can lead to wider utilization of Brassica carinata (Ethiopian mustard)
in food and feed industry.
Key words:
Brassica carinata, Brassica napus , interspecific hybrids, seed oil quality
