Assessing the level of genetic diversity within a germplasm collection contributes to evaluating the potential for its utilization as a gene pool to improve the performance of cultivars. In this study, 45 high-quality simple sequence repeat (SSR) markers were screened and used to estimate the genetic base of a world-wide collection of 248 rapeseed (Brassica napus) inbred lines. For the whole co...
In order to evaluate the effects of different levels of phosphorus (P) and boron (B) on yield, yield components, seed quality (protein and oil content) and P and B content of rapeseed (Brassica napus L.), a greenhouse experiment (aimed at removal of other environmental factors affecting growth parameters, which are not manageable in the field) was conducted. Treatments consisted of two cultivar...
Meloidogyne chitwoodi races 1 and 2 and M. hapla reproduced on 12 cultivars of Brassica napus and two cultivars of B. campestris. The mean reproductive factors (Rf), Rf = Pf at 55 days / 5,000, for the three nematodes were 8.3, 2.2, and 14.3, respectively. All three nematodes reproduced more efficiently (P < 0.05) on B. campestris than on B. napus. Amending M. chitwoodi-infested soil in plastic...
the diamondback moth, plutella xylostella (l.) (lep.: plutellidae) is one of the most destructive insectpests of cruciferous crops throughout the world. in this research, the demographic parameters of p. xylostellawere studied on five rapeseed cultivars including licord, modena, okapi, rgsoo3 and regxkobra. theexperiments were conducted in a growth chamber at temperature of 25 â± 1â°c, 60 â± 5%...
This study was designed to evaluate the role of growth regulator trinexapac and fungicides on growth, yield, and quality of winter rapeseed (Brassica napus L.). The experiment was conducted simultaneously at different locations in Germany using two cultivars of rapeseed. Five different fungicides belonging to the triazole and strobilurin groups, as well as a growth regulator trinexapac, were te...
This research was performed in 2011 at University of Mohaghegh Ardabili, Iran, to evaluate osmotic-stress tolerance, at seedling stage, of rapeseed (Brassica napus L.), as a split plot experiment based on randomized complete blocks design with four replications. Levels of osmotic stress were considered as main factor and twelve rapeseed cultivars were sub-factor, that were evaluated under aquac...
sowing date is an important determinant of yield in canola. cultivation of winter rapeseed cultivars in semi arid regions of iran however it has high potential for production, but, mentioned cultivars are late maturity and this late maturity cause to that silique formation and seed filling periods mature in the same time with hot and dry weather condition. in contrast, spring rapeseed cultivars...
The present work describes the effects of winter and spring genotypes of rapeseed (PF7045/91, Okapi and Opera), explants (cotyledons and hypocotyls), light, different kinds and concentrations of auxins [Naphthylacetic acid (NAA) and 2, 4dichlorophenoxyacetic acid (2, 4-D)], presence of cytokinin [benzyladenine (BA)] and different concentrations of micro and macro elements (MS and 1/2MS) on call...
Rapeseed (Brassica napus L.) is an important alternate oilseed crop in eastern Anatolia, Turkey. No information on plant density for rapeseed is available in this region. Therefore a study was initiated to investigate the effects of spacings between rows and spacings within rows on the yield and agronomic characteristics of two genotypes of spring rapeseed (Tower and Lirawell) in Erzurum, easte...
A greenhouse experiment was conducted in order to evaluate the influence of different nitrogen (N) and zinc (Zn) levels on yield, yield components, seed quality and N and Zn contents of two cultivars of rapeseed (Brassica napus L.). In this study, two cultivars of rapeseed (Talayeh and Opera), three N levels (100, 200 and 300 mg/kg) and three Zn levels (0, 5 and 10 mg/kg) with three replication...
