The effects of soil and plant nutrients on the oviposition preference, larval performance and spatial dynamics of Ceutorhynchus obstrictus and its parasitoidsDownload
The effects of nitrogen and sulfur fertilization on the oviposition, feeding preferences, and larval performance of Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae) on Brassica napus L. were examined in a series of laboratory experiments. The associations between C. obstrictus...
Broadening of genetic diversity in spring canola (Brassica napus L.) by use of yellow sarson and Canadian spring Brassica rapa L.Download
Canada is the top producer of Brassica oilseeds [B. napus L. (n = 19, AC genome)] in the world. Genetic diversity has declined in this crop in the recent years due to use of only superior and genetically narrow gene pool in breeding. Presence of adequate genetic diversity is important for further...
The nutritional value of biodiesel co-products were studied for swine. In Exp. 1, expeller-pressed canola meal was nutritionally characterized and validated for grower-finisher pigs. Expeller-pressed canola meal provided adequate energy and AA; ADG was reduced 3 g/d per 1% expeller-pressed canola...
The Impact of Clubroot Resistant Canola Cultivars on Plasmodiophora brassicae Resting Spore Concentrations in the SoilDownload
The soilborne pathogen Plasmodiophora brassicae Woronin, causal agent of clubroot of canola (Brassica napus L.), is difficult to manage due to the longevity of its resting spores, its ability to produce large amounts of inoculum, and the prohibitive costs of effective fungicides. The cropping of...
Effects of environmental and disturbance gradients on native bee diversity, abundance and composition in Alberta’s prairiesDownload
Native bees provide pollination services to a range of crops, supporting food production and the global economy. They also support the fitness of native flowering plants and terrestrial plant diversity. These functions are delivered by a diverse community of bees with a broad spectrum of life...
Sensitivity of Leptosphaeria maculans isolates to pyraclostrobin and assessment of fungicide efficacy in the management of blackleg of canolaDownload
Blackleg (Leptosphaeria maculans) disease is endemic to canola (Brassica napus) worldwide. With shortened canola rotations and increasing levels of blackleg in Alberta, Canada, growers may look to fungicides as an attractive disease management tool. However, the improper or intensive use of...
Evaluation of Genetic Diversity and Performance of the Inbred Lines Derived from B. Napus x B. Rapa Interspecific Crosses and Their Test HybridsDownload
ABSTRACTSpring Brassica napus L. canola (AACC, 2n = 38) is the second most important crop in Canada. Genetic diversity in this crop is narrow; therefore, broadening of the genetic base of this crop is needed for continued improvement through breeding. For this, the exotic gene pools of this...
Differences in Phyllotreta cruciferae and Phyllotreta striolata (Coleoptera: Chrysomelidae) responses to neonicotinoid seed treatmentsDownload
Abstract: Insecticidal seed treatments are used commonly throughout the Northern Great Plains of North America to systemically protect seedlings of canola (Brassica napus L. and Brassica rapa L.) from attack by the flea beetles Phyllotreta cruciferae (Goeze) and Phyllotreta striolata (F.)...
Further improving of seed yield, other agronomic and seed quality traits in spring canola Brassica napus requires broadening of genetic diversity in this crop. The European winter oilseed B. napus is known to be genetically diverse from spring oilseed B. napus. We hypothesized that elite spring...
A prepartum diet supplemented with oilseeds high in oleic or linoleic acid reduced GnRH-induced LH release in dairy cows during second week postpartumDownload
Background The objective was to determine the effect of prepartum diets supplemented with rolled canola seed (high in oleic acid) or sunflower seed (high in linoleic acid) on luteinizing hormone (LH) pulsatility and gonadotropin releasing hormone (GnRH)-induced LH release during early postpartum....
