Yield potentials of spring turnip rape (Brassica rapa L.) synthetics and composite hybrids were compared with those of open-pollinated commercial cultivars during a 3-yr period (2000–2002). The trials included 16 synthetics and 25 composite hybrids derived from 22 different parent lines, as well as five open-pollinated commercial cultivars. All of the material tested had low erucic acid and glucosinolate contents and was well adapted for cultivation in southern Finland. The composite hybrids, which were tested for the first time in turnip rape, exhibited significantly higher seed yields than open-pollinated cultivars. The maximum commercial heterosis in seed yield was 18% in synthetics and 23% in composite hybrids. Both synthetics and composite hybrids showed better resistance to lodging than commercial cultivars. When studying the effect of commercial heterosis on seed yield, a high degree of variation was observed both within the synthetics and the composite hybrids. This result highlights the importance of testing parental combinations in turnip rape in order to find combinations that give the strongest heterotic effect.

Low Erucic Acid

Brassica junceais a crucial cultivated mustard species and principal oilseed crop of India and Madhya Pradesh, grown for diverse vegetables, condiments, and oilseeds. Somaclonal variation was explored as a probable source of additional variability for the manipulation of fatty acids, especially low erucic acid contents that may be valuable for this commercially important plant species. The plantlets regenerated from tissue cultures (R0), their R1 generation and respective parental lines were compared for morpho-physiological traits and fatty acid profile for the probable existence of somaclonal variations. The first putative somaclone derived from genotype CS54 contained 5.48% and 5.52% erucic acid in R0 and R1 regenerants, respectively, compared to the mother plant (41.36%). In comparison, the second somaclone acquired from PM30 exhibited a complete absence of erucic acid corresponding to its mother plant (1.07%). These putative somaclones present a source of variation for exploitation in the development of future mustard crops with low erucic acid content.
