Abstract
Seven lines (generation T3 and T4) of transgenic oilseed rape c.v. ‘Drakkar’ (‘D’) carrying a thioesterase gene of Cuphea lanceolata were field released in 1996. Myristic acid content (C14:0%) of the offspring varied from 0.1% to 12.0%, the best single plant showing 17.7%. Mean parent-offspring correlation (T3/T4) was r=+0.86 with a maximum of 0.96. First results concerning inheritance of C14:0 % are reported.
There were no pronounced differences to ‘D’ in development and vigour.
In a yield trial with two transgenic lines and ‘D’ one line was significantly higher yielding (29.1 dt/ha) as compared to the second line (27.2 dt/ha) and ‘D’ (27.0 dt/ha). In a pilot experiment oil processing characteristics were not different to ‘D’, but the oxidation stability of the transgenics was markedly higher.
