Brassica napus Linnaeus is considered a self-compatible crop; however, studies show that bee foraging elevates their seed production. Considering bee food shortages during the winter season and that the canola is a winter crop, this study aimed to evaluate the foraging behaviour of Apis mellifera Linnaeus, 1758 regarding those flowers, and to verify if it presents adequate behaviour for success...

In the Botanical Garden and Research Laboratory of Institute Pure Applied Biology, Bahauddin Zakariya University, Multan (Pakistan) current work was performed to examine effect foliar spray potassium for lessening toxicity heavy metal in three varieties Canola (Brassica napus L.) viz; Exceed, Cyclone Legend. Seeds were grown pots. They arranged a Completely Randomized Design (CRD). When seeds g...

One of the most commonly seeded crops in Canada is canola, a cultivar of oilseed rape (Brassica napus). As a mass-flowering crop grown intensively throughout the Canadian Prairies, canola has the potential to influence pollinator success across tens of thousands of square kilometers of cropland. Bumble bees (Bombus sp.) are efficient pollinators of many types of native and crop plants. We measu...

Oil seed rape (Brassica napus L.) cultivars, donors of quality (SC) and self-incompatible (SI) lines have been analysed using identification of S-locus. In several Brassica napus cultivars one S-locus SLG gene was detected as dominant and the second S-locus as recessive. Amplification class II SLG gene screened recessive gene in all analysed samples (SC and SI). The DNA fragment of recessive ge...

Farmers in Mediterranean climate regions are increasingly growing canola (Brassica napus L.) wheat (Triticum aestivum L.)-based systems to break soil-borne pathogen disease cycles, control weeds, and enhance crop marketing opportunities. A 6-year rainfed cropping experiment was conducted near Ritzville, Washington USA from 2015 2021. The objective compare performance of winter spring canola, tr...

Canola (Brassica napus L.) is the second largest cash crop in Canada (4). Blackleg disease, caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph = Phoma lingam (Tode:Fr.) Desmaz.), is one of most economically important diseases of canola (21). In the past decade, canola production has expanded significantly worldwide and interest in the blackleg fungus, particularly its biology, ...

The effect of canola (Brassica napus) as a crop suppressive to Pratylenchus neglectus is in part due to the release of nematicidal isothiocyanates, particularly 2-phenylethyl isothiocyanate, from degrading root tissues. However, many cultivars of canola are relatively susceptible to P. neglectus and will fail to reduce soil populations of the nematode. A survey of B. napus accessions and closel...

Abstract The ideal-free distribution and central-place foraging are important ecological models that can explain the of organisms in their environment. However, this model ignores distance-based costs from a central place (hive, nest), whereas competition. Different currencies cooperation between foragers also create different optimal distributions foragers, but limited to simple two-patch mode...

We have generated a Brassica napus (canola) population of 3,158 EMS-mutagenised lines and used TILLING to demonstrate that the population has a high enough mutation density that it will be useful for identification of mutations in genes of interest in this important crop species. TILLING is a reverse genetics technique that has been successfully used in many plant and animal species. Classical ...
