Nutritional and Antioxidant Properties of Rapeseed (<i>Brassica Napus</i>) Cultivars with High and Low Erucic Acid Content

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.

The One

The interplant outcrossing rate was studied for one cultivar and four lines of rape (Brassica napus) and three cultivars of mustard (Brassica juncea) under field conditions at Saskatoon, Saskatchewan, in 1982, 1983 and 1984. Marker characters used for determining outcrossing rates were seed oil erucic acid content for rape and seed color for mustard. The average interplant outcrossing rate was 21.8% for rape and 18.7% for mustard. No significant differences in outcrossing rates among the one cultivar and the four lines of rape or the three cultivars of mustard were detected. A wide range in outcrossing rates between plants within cultivars and lines was observed for both species, but whether this variation was genetic or was environmentally induced could not be determined in these experiments. Some of the implications of this partial outcrossing on methods used for the breeding of these crops are discussed.Key words: Outcrossing, rape, mustard

Low Erucic Acid

Rapeseed-mustard is one of the most economically important oilseed crops in India. Speciality oils having high amounts of a specific fatty acid are of immense importance for both nutritional and industrial purposes. Oil high in oleic acid has demand in commercial food-service applications due to a long shelf-life and cholesterol-reducing properties. Both linoleic and linolenic acids are essential fatty acids; however, less than 3% linolenic acid is preferred for oil stability. High erucic acid content is beneficial for the polymer industry, whereas low erucic acid is recommended for food purposes. Therefore, it is important to undertake systematic characterization of the available gene pool for its variable fatty acid profile to be utilized for specific purposes. In the present study the Indian rapeseed-mustard germplasm and some newly developed low-erucic-acid strains were analysed by GLC to study the fatty acid composition in these lines. The GLC analysis revealed that the rapeseed-mustard varieties being commonly grown in India are characterized by high erucic acid content (30–51%) in the oil with low levels of oleic acid (13–23%). However, from among the recently developed low-erucic-acid strains, several lines were identified with comparatively high oleic acid (60–70%), moderate to high linoleic acid (13–40%) and low linolenic acid (< 10%) contents. Work is in progress at TERI (New Delhi, India) to utilize these lines for development of strains with particular fatty acid compositions for specific purposes.
