Selective control of canada thistle in rapeseed with 3,6-dichloropicolinic acid

Abstract: Control of Canada thistle (Cirsium arvense L. Scop.) topgrowth and regrowth, and tolerance of rapeseed (Brassica campestris L. and Brassica napus L.) to 3,6-dichloropicolinic acid at 0.2–0.3 kg/ha were excellent in greenhouse and field trials. Rapeseed yields following postemergence treatment were increased in 12 of 17 trials conducted on infested farm fields.

Transgenic Herbicide Tolerant Canola—The Canadian Experience

Abstract: Canola is a Canadian development, having been derived through conventional plant breeding of rapeseed (Brassica napus L. and B. rapa L.). The acceptance of canola in the marketplace has been assisted by the proliferation of new cultivars registered under the mandate of the Canadian Food Inspection Agency (CFIA). New cultivars, whether conventional or transgenic, are evaluated and approved for registration by a national committee known as the Western Canada Canola/Rapeseed Recommending Committee (WCC/RRC). Regulatory approval for transgenics is granted by the CFIA and Health Canada, who oversee the confined and unconfined release of these products into the environment. Transgenic canola cultivars, Roundup Ready {glyphosate [N-(phosphonomethyl)glycine] tolerant}, and Liberty Link {glufosinate [2-amino-4-(hydroxymethylphosphinyl)butanoic acid] tolerant} were first registered in Canada in 1995, while Navigator [bromoxynil (3,5-Dibromo-4-hydroxybenzonitrile) tolerant] cultivars appeared later. Herbicide tolerant (HT) transgenics have enjoyed increased market share since their development, and now occupy ≈55% of the canola acreage in western Canada. The popularity of these cultivars appears to arise more from agronomic rather than economic advantages. Tolerance tests have failed to show any significant effect of the herbicides on the cultivars.

Effect of microwave treatment on the efficacy of expeller pressing of Brassica napus rapeseed and Brassica juncea mustard seeds.

Abstract: A study was conducted to evaluate the effect of microwave heating on the efficacy of expeller pressing of rapeseed and mustard seed and the composition of expeller meals in two types of Brassica napus rapeseed (intermediate- and low-glucosinolate) and in Brassica juncea mustard (high-glucosinolate). Following microwave treatment, the microstructure of rapeseed using transmission electron microscopy showed a significant disappearance of oil bodies and myrosin cells. After 6 min of microwave heating (400 g, 800 W), the oil content of rapeseed expeller meal decreased from 44.9 to 13.5% for intermediate-glucosinolate B. napus rapeseed, from 42.6 to 11.3% for low-glucosinolate B. napus rapeseed, and from 44.4 to 14.1% for B. juncea mustard. The latter values were much lower than the oil contents of the corresponding expeller meals derived from the unheated seeds (i.e., 26.6, 22.6, and 29.8%, respectively). Neutral detergent fiber (NDF) contents showed no differences except for the expeller meal from the interm...

Agrobacterium -Mediated Transformation of Canola

Abstract: Canola (Brassica napus L.) is an important oil crop, ranking third only to soybean and palm oil in global production. It is a member of the family Brassicacea (syn. Cruciferae). It is a winter or spring crop and is amenable to growth in cooler climates. Once considered a specialty crop for Canada, it is now a global crop. Many other countries including the USA, Australia and those in Europe also grow canola. However, Canada and the United States account for most of the canola crop. It is grown mostly in Western Canada and North Central United States. In the year 2002, in Canada alone, 9.6 million acres of canola was grown (1) and in the USA, 1.5 million acres was devoted to canola cultivation (2). The term ‘canola’ was adopted by Canada apparently as an acronym of the Canadian Oilseed Association in 1979. Although canola has been commonly also known as rapeseed or oilseed rape, in the strict sense canola oil is defined as an oil that must contain less than 2% erucic acid, and the solid component of the seed must contain less than 30 μM of any one or a mixture of 3-butenyl glucosinolate, 4-pentenyl glucosinolate, 2-hydroxy-3 butenyl glucosinolate, and 2-hydroxy-4-pentenyl glucosinolate per gram of air-dry, oil-free solid.
