“…Although dark seeded genotypes are grown almost exclusively in Canada at this time, yellow seeded B. napus is higher in seed oil and lower in chlorophyll content (Rakow and Raney 1993) than dark seeded genotypes. Meal from yellow seeded B. napus and B. rapa also tended to have greater seed protein (0.6 to 3.7%) and seed sucrose (1.4 to 2.8%) (Simbaya et al 1995). Dietary fibre was correlated negatively to protein content, while most other nutritional parameters were not different between seed coat colour classes in the latter study.…”

. 2008. The Biology of Canadian Weeds. 137. Brassica napus L. and B. rapa. Can. J. Plan Sci. 88: 951Á996. Brassica napus and B. rapa are native to Eurasia. In Canada, these species are commonly referred to as volunteer canola, while feral populations of B. rapa are referred to as birdrape. Brassica napus and B. rapa have been grown commercially for their seed oil content in western Canada since the middle of the last century and volunteer populations are common in fields. Escaped populations of both species are also found along roadways, railways and in waste areas; however, only B. rapa is known to have naturalized, self-sustaining feral populations in these habitats in eastern Canada. Despite these escaped and feral populations, B. napus and B. rapa are mainly a concern in agricultural fields where their combined relative abundance has increased over the past few decades. In the mid 1990s, herbicideresistant genotypes of B. napus were released for commercial production. Herbicide-resistance and the stacking of genes in volunteer populations conferring resistance to multiple herbicides have contributed to increased difficulties in controlling volunteer B. napus in some crops. However, yield loss resulting from volunteer populations is not well documented in Canada.Key words: Brassica napus, Brassica rapa, herbicide resistance, transgene escape, volunteer canola, weed biology Gulden, R.

Brassica napus et B. rapa sont des plantes originaires d'Eurasie. Au Canada, on les de´signe souvent sous l'expression « canola spontane´», tandis que les peuplements sauvages de B. rapa sont appele´s « navette ». Dans l'Ouest canadien, Brassica napus et B. rapa sont cultive´s commercialement pour l'huile que renferment leurs graines depuis le milieu du sie`cle dernier et les repousses spontane´es sont devenues monnaie courante dans les champs. On observe des peuplements des deux espe`ces le long des routes et des voies ferre´es ainsi que dans les terrains vagues, cependant on sait que seule B. rapa s'est acclimate´e pour donner des populations sauvages et stables dans les meˆmes habitats, dans l'est du pays. Malgre´cela, B. napus et B. rapa demeurent surtout pre´occupants dans les cultures, oul eur abondance relative, une fois combine´s, s'est accrue au cours des dernie`res de´cennies. Au milieu des anne´e 1990, des ge´notypes de B. napus re´sistants aux herbicides ont e´te´homologue´s pour la culture commerciale. Cette re´sistance et l'accumulation des ge`nes qui la codent dans les peuplements spontane´s ont concouru a`compliquer la lutte contre les repousses de B. napus dans certaines cultures. Quoi qu'il en soit, les pertes de rendement qui en re´sultent sont mal e´taye´es au Canada.

“…Since un-pigmented natural variants of B. napus have never been observed, yellow-seeded (YS) rapeseed lines with reduced pigment contents were developed through introgressions of the trait from related Brassica species for which YS genotypes naturally exist (B. rapa, B. juncea, B. carinata) (Rahman 2001). The resulting YS rapeseed genotypes display a reduction of their testa thickness that is correlated with higher contents in both oil and proteins, a lower content in fibres and therefore an improved meal nutritional value compared to their black-seeded counterparts (Simbaya et al 1995;Slominski et al 1999). …”

The promoter of the Arabidopsis thaliana BAN gene is active in proanthocyanidin-accumulating cells of the Brassica napus seed coat

As part of an ongoing research program dedicated to the understanding of proanthocyanidin (PA) accumulation in Brassica napus seed coat, transgenic rapeseed plants carrying a 2.3-kb fragment of the Arabidopsis thaliana BAN promoter (ProAtBAN) fused to the uidA reporter gene (GUS) were generated. Analysis of these plants revealed that ProAtBAN was activated in B. napus seed coat, following a spatio-temporal pattern that was very similar to the PA deposition profile in rapeseed and also to the one previously described in Arabidopsis. ProAtBAN activity occurred as soon as the early stages of embryogenesis and was restricted to the cells where PAs were shown to accumulate. Therefore, the Arabidopsis BAN promoter can be used to trigger gene expression in B. napus seed coat for both genetic engineering and functional validation of candidate genes. In addition, these data strongly suggest that the transcriptional regulatory network of the BAN gene is conserved between Arabidopsis and rapeseed. This is consistent with the fact that similarity searches of the public rapeseed sequence databases allowed recovering the rapeseed homologs for several BAN regulators, namely TT1, TT2, TT8, TT16 and TTG1, which have been previously described in Arabidopsis.

“…Rapeseed meal has a high protein content and is an excellent feed for animals (Goding et al 1972;Huisman & Tolman 1990). The overall nutritive value of rapeseed is not lower than that of soybean (Simbaya et al 1995).…”

Dynamic genetic effects on threonine content (TC) of rapeseed (Brassica napus L.) meal were analysed at 5 developmental times/stages using the genetic models for diploid plant seeds. Results indicated that the expression of diploid embryo, cytoplasmic and diploid maternal plant genes were all important for the performance of TC at various developmental times/stages of rapeseed, especially at the early and middle developmental stages. Among different genetic systems, TC was mainly controlled by the cumulative or net maternal main effects and the genotype × environment (GE) interaction effects, followed by the embryo main effects and GE interaction effects. The expression of genes was more easily influenced by the environmental factors at the first three developmental stages. The total narrow-sense heritabilities for TC on 15, 22, 29, 36 and 43 days post anthesis were 46.50, 62.60, 57.10, 84.70 and 59.50%, respectively, of which the interaction heritabilities were more important at the first three developmental stages of rapeseed. The improvement in TC of rapeseed meal could be expected by selection based on the higher narrow-sense heritabilities near maturity. The predicted genetic effects of parents showed that TC of progeny could be improved by using the parent Gaoyou 605.
