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

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.

HYHEAR 1 hybrid Roundup Ready™ high erucic acid, low glucosinolate summer rape. Can. J. Plant Sci. 94: 453–455. HYHEAR 1 summer rape (Brassica napus L.) is the world's first hybrid Roundup Ready™ high erucic acid, low glucosinolate cultivar. On average, HYHEAR 1 yielded 33% more seed, 23 g kg−1 more seed oil but 17 g kg −1 less meal protein than MillenniUM 03 high erucic acid, low glucosinolate, open pollinated population summer rape. HYHEAR 1 has an erucic acid content of 52.2% in isolated field trials of HEAR lines and is adapted to the southern B. napus growing regions of western Canada.

Ethiopian mustard (Brassica carinata A. Braun) is a highly productive oilseed crop in the central highlands of Ethiopia. Cultivars currently in production in Ethiopia produce seed which contains 35–40% erucic acid in its oil which is undesirable for human consumption. Zero erucic acid B. carinata has recently been developed. The objective of this study was to investigate the inheritance of erucic acid in progeny of crosses between the high erucic acid cultivars Dodolla and S-67 with the zero erucic acid line C90-14. The erucic acid content of F1 seed born on either the high or low erucic acid parents was intermediate between the parents indicating embryonic control of erucic acid content in B. carinata. Erucic acid contents of backcross seed derived from the backcross to the zero erucic acid parent segregated into three classes with <0.5%, 6–16% and >16% erucic acid at a ratio of 1:2:1 and F2 seed segregated into five classes with a ratio of 1:4:6:4:1. These segregation patterns indicated that erucic acid in B. carinata was controlled by two genes acting in an additive manner with each locus contributing about 10% erucic acid. It was concluded that the B and C genomes of B. carinata each carry one gene for erucic acid synthesis. The knowledge of the inheritance of erucic acid in B. carinata will assist in the development of zero erucic acid B. carinata cultivars. Key words:Brassica carinata, erucic acid, inheritance
