| Abstract: | Ethiopian mustard (Brassica carinata Braun) is a potential oil crop for the rain-fed Mediterranean area. However, its usage is limited by the high erucic and high glucosinolate content of the oil and meal, respectively. In the course of a mutagenesis programme, an agronomically good line of Ethiopian mustard was treated with EMS in order to widen the natural variability of nutritional traits in this species. As a result of this programme several low erucic mutants were isolated; two of these mutants showed erucic acid values in the M4 generation in the range 5–10% of total fatty acids. Near-infrared reflectance spectroscopy (N1RS) was successfully applied as a rapid screening method for erucic acid in this breeding programme. |
