Abstract The cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae), is an invasive pest infesting canola (Brassica napus L. and B. rapa (Brassicales: Brassicaceae)) crops in North America. Larval feeding causes significant damage leading to yield losses of 5–30%. Native the Palearctic region, species was accidentally introduced America over 90 yr ago, now occupi...

Canola (Brassica napus L. var. oleracea) is the third most common oil-producing crop worldwide after palm and soybean. cultivation requires use of chemical fertilizers, but amount required can be reduced by applying plant growth-promoting bacteria (PGPB). Among PGPB, endophytic have certain advantages as biofertilizers, canola rarely been studied. In this work, we identified a collection bacter...

Winter canola generally produces greater yields than spring canola. However, its range is limited due to inability withstand the harsh winter conditions that occur in many northern regions of U.S.A. To identify loci associated with freezing tolerance canola, we conducted a genome-wide association study (GWAS) using genotyped diversity panel containing 399 accessions consisting primarily One-mon...

Oilseed rape (Brassica napus) or Canola is an important oilseed crop produced and consumed globally. The predicted increase in the frequency of high-temperature events associated with climate change poses a threat to productivity. In present work, we report impact short-term heat stress on reproductive fitness yield components Canola. Short episodes, especially above 36°C, resulted diminished d...

Salinity is a major environmental factor that influences rapeseed production in arid and semi-arid regions of central and southern Iran. In this study, effect of applied NaCl on shoot and root growth and distribution and accumulation of Na, Cl, K, Ca and Mg in the canola plant (Brassica napus L. cv: Hayola 308 and cv: PP 401) was investigated. The experiment was arranged in a completely randomi...

Under normal field growth conditions, canola (Brassica napus) seeds produce chloroplasts during early seed development and then catabolize the photosynthetic machinery during seed maturation, producing mature seeds at harvest that are essentially free of chlorophyll (Chl). However, frost exposure early in canola seed development disrupts the normal programming of Chl degradation, resulting in g...
