A water-soluble chlorophyll protein (WSCP) in cauliflower (Brassica oleracea L.) was purified and its N-terminal sequence was determined. Forty-six of 48 residues of the sequence completely matched those of the drought-induced 22-kD protein (BnD22) in rapeseed (Brassica napus L.). All 40 sequenced residues of WSCP from rapeseed were perfectly matched to those of BnD22. Thus, WSCP may be identic...

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...

The US industry uses :18 million kg of high erucic acid oil annually, mostly from imports. Therefore, a large overall market potential exists for development of annually renewable domestic sources of erucic acid. The present research was conducted to characterize the winter hardy rapeseed germplasm for oil, erucic acid, and glucosinolate contents for use in breeding programs to develop commerci...

Nitrogen (N) transfer is well documented in legume-cereal intercropping but this is less often reported for legume-Brassica intercrops even though Brassica crops require higher levels of N fertilizers. The present study was carried out to quantify N transfer from legumes (Lupinus albus L., Trifolium incarnatum L. or Vicia sativa L.) to rapeseed (Brassica napus L.) using the split-root (15)N-lab...

Soil salinity is a serious threat to agriculture sustainability worldwide. Salt tolerance at the seedling stage is crucial for plant establishment and high yield in saline soils; however, little information is available on rapeseed (Brassica napus L.) salt tolerance. We evaluated salt tolerance in different rapeseed accessions and conducted a genome-wide association study (GWAS) to identify sal...

We developed Diversity Array Technology (DArT) markers for application in genetic studies of Brassica napus and other Brassica species with A or C genomes. Genomic representation from 107 diverse genotypes of B. napus L. var. oleifera (rapeseed, AACC genomes) and B. rapa (AA genome) was used to develop a DArT array comprising 11 520 clones generated using PstI/BanII and PstI/BstN1 complexity re...

An Illumina Infinium array comprising 5306 single nucleotide polymorphism (SNP) markers was used to genotype 175 individuals of a doubled haploid population derived from a cross between Skipton and Ag-Spectrum, two Australian cultivars of rapeseed (Brassica napus L.). A genetic linkage map based on 613 SNP and 228 non-SNP (DArT, SSR, SRAP and candidate gene markers) covering 2514.8 cM was const...

Rapeseed (Brassica napus L.) and mustard juncea are two important oilseed crops grown worldwide for edible oil meal production, as well as, a source of renewable energy. Silique shattering at the maturity stage is major cause seed yield reduction in brassica. Losses more developing countries due to poor management non-availability combine harvesters. resistance essential achieving good especial...

Assessment of Spatial Variation Soil Physical Quality in a Rapeseed (Brassica napus) Field Bilavar, Kermanshah

A pot experiment was conducted to study the effects of arsenic (As) and sulfur (S) interaction on yield and their accumulation and distribution in rapeseed (Brassica napus L.). The results showed that (1) at the same level of S treatment, application of As significantly decreased rapeseed grain and biomass yield; (2) Application of S significantly increased the grain and biomass yield of rapese...
