Evaluation of growth and seed yield of new winter oilseed rape (Brassica napus L.) genotypes under terminal drought stress conditions
Breeding and production of drought tolerant cultivars for arid and semi-arid area is very important. The present experiment was carried out to evaluate the effects of drought stress on seed yield and yield components of oilseed rape as well as identification of high yielding and drought stress tolerant genotypes. Eighteen new winter oilseed rape lines and commercial cultivars were evaluated und...
متن کاملInterrelationships among grain yield and related characters of four oilseed rape (Brassica napus L.) cultivars under drought stress conditions
Four rapeseed cultivars (Hayola 401, Hayola 308, RGS and Option) were evaluated for some physiological traits under stress (50 % field capacity (FC) and non-stress (irrigated) conditions. The factorial set of treatments was arranged within a randomized complete block design with three replications. The collected data were analyzed using path and factor analyses. These is results showed that...
متن کاملHybridization and backcrossing between transgenic oilseed rape and two related weed species under field conditions.
Determining the frequency of crop-wild transgene flow under field conditions is a necessity for the development of regulatory strategies to manage transgenic hybrids. Gene flow of green fluorescent protein (GFP) and Bacillus thuringiensis (Bt) transgenes was quantified in three field experiments using eleven independent transformed Brassica napus L. lines and the wild relatives, B. rapa L. and ...
متن کاملStomatal compensation points for ammonia in oilseed rape plants under field conditions
Compensation points for gaseous exchange of ammonia (NH3) between stomata and the atmosphere were determined in an oilseed rape (Brassica napus) canopy by analysing the concentrations of NH4+ and H+ in leaf apoplastic solution. This bioassay approach was applied for the first time in the field, allowing the first intercomparison with compensation points derived from micrometeorological measurem...
متن کاملInterrelationships among oilseed rape (Brassica napus L.) grain yield and weed growth under different nitrogen levels
Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...
