Optimisation of trierucin content in oilseed rape
High erucic acid rapeseed (HEAR) cultivars have regained interest for industrial purposes because erucic acid (22:1) is a valuable feedstock with a wide range of applications especially if it is available in sufficient quantities and in sufficiently pure form. In HEAR oil, however, the 22:1 content …

Characteristics of phosphatidate phosphatase from developing seeds and microspore-derived cultures of oilseed rape
… seeds and microspore-derived (MD) cultures of oilseed rape. In studies with homogenate from developing seeds (Brassica napus L. cv Westar) the time course for release of inorganic phosphate from phosphatidate was linear for at least 60 min and the enzyme was stable to at least three cycles of …

A Genetic Approach towards Modulating Pre-Harvest Pod Shatter in Brassica napus (Oilseed Rape)
Pre-harvest pod-shattering in Brassica napus (Oilseed Rape) is a serious agricultural and economic problem, with losses of 11-25% reported (Price et al., 1996) resulting in lost revenues of an estimated £66 million per annum for the U.K. alone. Reductions in this loss will provide benefits for both …

A molecular genetic analysis of resistance to poleroviruses in sugar beet and oilseed rape
… reduction in the yields of sugar beet and oilseed rape respectively. Both viruses are transmitted by the aphid vector Myzus persicae. Current control methods rely heavily on the use of insecticides for controlling the aphids which can spread these viruses to a wide range of host plants. …

Linking germination traits of oilseed rape (<i>Brassica napus</i> L.) to DNA markers
Oilseed rape has become an important weed in arable rotations and a feral plant of field margins, soil dumps and roadsides. Seed persistence in the soil following induced secondary dormancy is thought to perpetuate these weed and feral populations. Potential variation between cultivars has been …

Feral oilseed rape populations within a scottish landscape : Implications for GM coexistence and environmental risk assessment
… many regions of the world, the crop, oilseed rape (Brassica napus), is giving rise to populations of volunteer weeds in fields and feral plants outside fields, both of which can retain crop genes and hybridize with compatible wild relatives. Feral oilseed rape has received global …

Control of Turnip yellows virus: Assessing impact on oilseed rape quality traits and dissecting circulative transmission by aphids
… is one of the most significant viral diseases of oilseed rape and may be one of main reasons why commercial oilseed rape crops do not reach their genetic potential. TuYV is transmitted by aphids, sap-sucking hemipteroid insects, and the green peach aphid (GPA) is the predominant vector. TuYV can …

The role of foliar glucosinolates in host plant resistance of oilseed rape and mustard to the Bertha armyworm and the diamondback moth
… investigated. M. configurata reared on eight rape and mustard varieties had significantly different final weights by species order Brassica juncea <Sinapis alba < B. napus < B. rapa. In choice tests, B. juncea was least preferred while S. alba was significantly more attractive than rape to …

Oilseed rape: A study of production and end uses : A dissertation submitted in partial fulfilment of the Diploma in Farm Management at Lincoln College
… principles and practices of growing a successful oilseed rape crop. It also looks in to the commercial side of marketing the oilseed produce.

Selective Control o Egyptian Broomrape (Orobanche Aegyptiacapers.) by Glyphosate and its Amino Acid Status in Relation to Selected Hosts
Broomrapes are achlorophyllous holoparasites of many economically important dicotyledonous crops. As weeds, they cause reductions in crop yield, adversely affect crop quality, and result in loss of cultivated land due to reduced crop alternatives. Few effective control measures exist for …

The Role of Carotenoid Cleavage Dioxygenase 4 in Flower Color of the Allopolyploid Brassica napus
… <em>Brassica napus</em> (farmed as canola or oilseed rape). With white-flowering and yellow-flowering progenitors, flower color phenotype of <em>B. napus </em>presents an opportunity to examine subgenomic interactions. <em>CAROTENOID CLEAVAGE DIOXYGENASE</em> 4 (<em>CCD4</em>)<em> </em>is …

HERBICIDE TRANSPORT FROM LAND TO SURFACE WATER IN AN ARTIFICIALLY DRAINED CATCHMENT
… 2009 to March 2010, when the field was in oilseed rape (OSR) and was treated with propyzamide and carbetamide. In the UK recent attention has focused on these two herbicides, which are used to control black grass in OSR. Both chemicals were detected at very high concentrations (up to 55.7 …

Crop Rotations for Sustainable Intensification
… and the productivity of winter wheat and winter oilseed rape. In contrast, cereal-dominated rotations were associated with lower NUE and yield penalties. A major methodological contribution of the dissertation is the development of a transferable spectral reflectance framework for canopy …

Identifying and dissecting novel QTL regulating seed fatty acid composition in Arabidopsis thaliana for the improvement of rapeseed oil
… identified by mutation analyses and utilized in oilseed rape (Brassica napus) breeding programs. However the regulation mechanisms of these genes are as yet unknown and pursued by the oil industry for further manipulation of seed oil quality. In order to identify loci involved in such regulatory …

The diversity of flower-visiting insects in the gardens of English country houses
… research assessing the benefits crops such as oilseed rape derive from the presence of insects in nearby rural gardens would be a useful addition to this work. Overall, the gardens of English country-houses emerge as sites of important natural as well as cultural heritage.

Assessing the ecological vulnerability of natural flood defences and risks to agricultural land following seawater flooding
… species varied considerably. Indeed, barley and oilseed rape were tolerant, while wheat and rice were extremely sensitive. Furthermore, aside from species-specific differences, relative tolerance shifted with crop ontogeny. These results are critical to understanding which species can be reliably …
