Ethiopian mustard (Brassica carinata A. Braun) is a high-yielding oilseed crop of the Ethiopian highlands, but the seed is high in erucic acid. The objective of this study was to develop zero erucic acid forms in this mustard species. This was achieved through an interspecific transfer of genes for zero erucic acid from Brassica juncea.

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

SUMMARYTwenty one strains of Brassica carinata were tested under irrigated, rainfed and saline soil conditions and five strains under late sowing conditions along with five varieties each of B. juncea, B. napus and B. campestris var. yellow sarson, brown sarson and toria. Brassica juncea had the largest seed and oil yield under irrigated conditions but B. carinata performed much better than other species under late sowing, rainfed and saline soil conditions.

Can. J. Plant Sci. 91: 889–896. Increased demand for biodiesel feedstock has encouraged greater napus canola (Brassica napus L.) production, but there may be a need for greater production of other oilseed crops for this purpose. A multi-site field study was conducted to determine the oil yield potential of various crops relative to that of napus canola in the semi-arid, short-season environment of the Canadian prairies. Oilseed crops evaluated included rapa canola (Brassica rapa L.), juncea canola (Brassica juncea L.), Ethiopian mustard (Brassica carinata L.), oriental mustard (Brassica juncea L.), yellow mustard (Sinapis alba L.), camelina (Camelina sativa L.), flax (Linum usitatissimum L.), and soybean [Glycine max (L.) Max.]. Crop emergence and growth were generally good for all crops, but soybean did not fully mature at some locations. The number of site-years (out of a total of 9) that crops attained similar or greater yields compared to napus canola were camelina (6), oriental mustard (5), juncea canola (3), flax (3), soybean (3), rapa canola (2), yellow mustard (2), and Ethiopian mustard (1). The ranking of seed oil concentration was napus canola=rapa canola= juncea canola=flax>camelina=oriental mustard>Ethiopian mustard>yellow mustard>soybean. Considering yield and oil concentration, the alternative oilseed crops exhibiting the most potential for biodiesel feedstock were camelina, flax, rapa canola and oriental mustard. Oils of all crops were easily converted to biodiesel and quality analyses indicated that all crops would be suitable for biodiesel feedstock with the addition of antioxidants that are routinely utilized in biodiesel fuels.

Ethiopian mustard (Brassica carinata A. Braun) is grown as an oilseed crop in Ethiopia. The agronomic performance and seed quality of 11 B. carinata lines were evaluated for 2 yr in field tests at Saskatoon, Saskatchewan, to asses the potential of Ethiopian mustard as an oilseed crop for the Canadian prairies. The B. carinata accessions were 5 d later flowering and 19 d later maturing than the B. napus cultivar Westar. Seed yields of B. carinata were comparable to those of B. napus in 1984, but were much lower than those of B. napus and B. juncea in 1985. Seed of B. carinata had higher protein and lower oil and crude fibre contents than that of B. napus and B. rapa. The fatty acid composition of the oil of B. carinata seed was typical for that of a high erucic acid Brassica oil. Allyl glucosinolate was the only alkenyl glucosinolate found in B. carinata seed meal. A comparison of near isogenic yellow and brown B. carinata lines indicated that, on average, yellow lines produced heavier seed (+ 0.4 g), higher oil (+ 23 g kg−1) and protein (+ 21 g kg−1) and lower crude fibre (− 12 g kg−1) contents than brown lines. Correlation studies showed that seed weight was positively correlated with oil and protein and negatively correlated with fibre content. The results of this study indicated that none of the 11 lines of B. carinata tested was adapted for immediate production on the Canadian prairies. Earlier-maturing, higher-oil-content lines of B. carinata that produce low erucic acid and low glucosinolate seed must be developed before this species can be grown as an oilseed crop in Canada.

Brassica juncea L. is the most widely cultivated oilseed crop in Indian subcontinent. Its seeds contain oil with very high concentration of erucic acid (≈50%). Of late, there is increasing emphasis on the development of low erucic acid varieties because of reported association of the consumption of high erucic acid oil with cardiac lipidosis. Erucic acid is synthesized from oleic acid by an elongation process involving two cycles of four sequential steps. Of which, the first step is catalyzed by β-ketoacyl-CoA synthase (KCS) encoded by the fatty acid elongase 1 (FAE1) gene in Brassica. Mutations in the coding region of the FAE1 lead to the loss of KCS activity and consequently a drastic reduction of erucic acid in the seeds. Molecular markers have been developed on the basis of variation available in the coding or promoter region(s) of the FAE1. However, majority of these markers are not breeder friendly and are rarely used in the breeding programs. Present studies were planned to develop robust kompetitive allele-specific PCR (KASPar) assays with high throughput and economics of scale. We first cloned and sequenced FAE1.1 and FAE1.2 from high and low erucic acid (&lt;2%) genotypes of B. juncea (AABB) and its progenitor species, B. rapa (AA) and B. nigra (BB). Sequence comparisons of FAE1.1 and FAE1.2 genes for low and high erucic acid genotypes revealed single nucleotide polymorphisms (SNPs) at 8 and 3 positions. Of these, three SNPs for FAE1.1 and one SNPs for FAE1.2 produced missense mutations, leading to amino acid modifications and inactivation of KCS enzyme. We used SNPs at positions 735 and 1,476 for genes FAE1.1 and FAE1.2, respectively, to develop KASPar assays. These markers were validated on a collection of diverse genotypes and a segregating backcross progeny. KASPar assays developed in this study will be useful for marker-assisted breeding, as these can track recessive alleles in their heterozygous state with high reproducibility.

Among the oilseed Brassica crops, Indian mustard [Brassica juncea (L.) Czern and Coss.] is an important source of oil from a nutritional point of view. The nutritional value of oil and cake quality is governed mainly by the composition of its fatty acids, iodine value, saponification, acid value, glucosinolates, crude fibre, protein and limiting amino acids, etc. Seventeen varieties/strains of Indian mustard were taken for saturated and unsaturated fatty acid analysis. The eicosenoic was absent in genotype (NUDBYJ-10) and erucic acid (NUDBYJ-10, LES-46 and Pusa mustard- 21). The fatty acid composition found a variable in different genotypes. Saturated fatty acid, Palmitic + Stearic ranged between 2.3 to 6.5%, Oleic 10.6 to 40.7%, Linoleic 16.1 to 37.7%, Linolenic 13.3 to 26.7%, Eicosenoic 0.00 to 10.30% and Erucic acid 0.00 to 47.50%, respectively. Alternaria blight severity also varied in different genotypes and ranged between 18.75 to 56.25%, maximum being in genotype Kranti and minimum in LES-47. No significant correlation was observed between the fatty acid composition and disease severity. The oil content range from 38.1 to 42.60% and protein content was found highest in variety RGN-73. The amino acid viz. methionine and tryptophan range between 0.41 to 1.81 g/16gN and 0.41 to 1.81 g /16g N, respectively.
