Meal Quality

The effect of time of sowing on the oil and meal quality of rapeseed (Brassica napus L. cv. Marnoo) was investigated at Werribee, Victoria, during 198 1 and 1982. In both years oil content declined with later sowing but the proportion of erucic acid in the oil was unaffected by sowing time. In contrast, later sowing increased the glucosinolate content of the seed meal, with July-September sowings exceeding the Canola standard. This increase was due primarily to the increased content of 2-hydroxybut-3- enyl glucosinolate (progoitrin).

Rapeseed Production

OAC Triton is the first licensed, triazine-resistant spring rapeseed (Brassica napus L.). It produces seed low in erucic acid and glucosinolate content. Yield levels have averaged approximately 80% of Regent and oil content has averaged 2.4% less than Regent. OAC Triton is expected to be used where rapeseed production is restricted or inhibited by serious cruciferous weed infestations, other triazine-susceptible weed problems, or by atrazine herbicide residues.Key words: Rapeseed, triazine-resistant, Brassica napus L., canola, cultivar description

Brassica Napus L

Glucosinolate content of rapeseed (Brassica napus L.) meal was investigated in parental, hybrid and segregating populations derived from the cultivar Bronowski, and a strain derived from Target. The gluconapin, glucobrassicanapin and progoitrin content of seed meal was determined by the genotype of the maternal plant, rather than the embryo genotype. Higher values of gluconapin were partially dominant to the lower values. Three loci were indicated in the control of gluconapin content. Overdominance of high values of glucobrassicanapin was demonstrated. Four or five loci probably control glucobrassicanapin content. The high values of progoitrin were partially dominant to the absence of progoitrin. Four loci were indicated for progoitrin. The gene systems controlling the three compounds did not segregate independently of each other.

Developmental Switches

Transcription factors (TFs) and their complex interplay are essential for directing specific genetic programs, such as responses to environmental stresses, tissue development, or cell differentiation by regulating gene expression. Knowledge regarding TF–TF cooperations could be promising in gaining insight into the developmental switches between the cultivars of Brassica napus L., namely Zhongshuang11 (ZS11), a double-low accession with high-oil- content, and Zhongyou821 (ZY821), a double-high accession with low-oil-content. In this regard, we analysed a time series RNA-seq data set of seed tissue from both of the cultivars by mainly focusing on the monotonically expressed genes (MEGs). The consideration of the MEGs enables the capturing of multi-stage progression processes that are orchestrated by the cooperative TFs and, thus, facilitates the understanding of the molecular mechanisms determining seed oil content. Our findings show that TF families, such as NAC, MYB, DOF, GATA, and HD-ZIP are highly involved in the seed developmental process. Particularly, their preferential partner choices as well as changes in their gene expression profiles seem to be strongly associated with the differentiation of the oil content between the two cultivars. These findings are essential in enhancing our understanding of the genetic programs in both cultivars and developing novel hypotheses for further experimental studies.

Ad Libitum

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.
