Because rapeseed, especially canola, has the potential to be grown in rotation with sugarbeet in the north-central region of the United States, this study was initiated to assess its susceptibility to infection by Heterodera schachtii and to develop a screening method for Brassica germplasm. Existing methodology was adapted for growing Brassica juncea, B. napus, B. rapa, Brassica hybrids, and s...

We conducted a long-term investigation to ascertain effects on honey bee, Apis mellifera L., colonies during and after exposure to flowering canola, Brassica napus variety Hyola 420, grown from clothianidin-treated seed. Colonies were placed in the middle of 1-ha clothianidin seed-treated or control canola fields for 3 wk during bloom, and thereafter they were moved to a fall apiary. There were...

Abstract A collection of isolates the fungi Leptosphaeria maculans and L . biglobosa , which cause blackleg disease on Brassica napus (canola/oilseed rape) other Brassicaceae species, was assembled to represent global diversity these pathogens a resource for international research. The consists 226 (205 21 ) from 11 countries. genomes all 205 were sequenced, distribution identity avirulence gen...

Under the current climate change scenario, water stress is one of key factors that reduce production crops. Gibberellic acid (GA3) an efficient endogenous plant hormone shows a vital role in growth and development. Production canola (Brassica napus L.) its oil contents are severely affected under drought stress. The present study was conducted to investigate potential GA3 alleviating canola. Th...

Canola (Brassica napus L. and B. rapa L.), is one of the major oilseed crops grown worldwide. With significant expansion of acreage sown to canola during the past two decades, concern about blackleg, the most serious disease of canola, has increased (3,4). Blackleg disease is caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph: Phoma lingam (Tode:Fr.) Desmaz.). The pathogen can ...

The allotetraploid species Brassica napus L. is a global crop of major economic importance, providing canola oil (seed) and vegetables for human consumption and fodder and meal for livestock feed. Characterizing the genetic diversity present in the extant germplasm pool of B. napus is fundamental to better conserve, manage and utilize the genetic resources of this species. We used sequence-base...

Earliness of flowering and maturity are important traits in spring Brassica napus canola-whether grown under long- or short-day condition. By use of a spring B. napus mapping population carrying the genome content of B. oleracea and testing this population under 10 to 18 h photoperiod and 18 to 20 0C (day) temperature conditions, we identified a major QTL on the chromosome C1 affecting flowerin...

Cropping sequences integrating perennial forages and annual crops can generate multidimensional agroeconomic environmental benefits. A 4-yr cropping sequence study was conducted from 2013 to 2016 evaluate the relative merits of various sequences. Three forage seed (creeping red fescue [Festuca rubra L.], alsike clover [Trifolium hybridum pratense L.]) four food (wheat [Triticum aestivum canola ...
