Production of allohexaploid Brassica (2n = AABBCC) is a promising goal for plant breeders due to the potential for hybrid heterosis and useful allelic contributions from all three of the Brassica genomes present in the cultivated diploid (2n = AA, 2n = BB, 2n = CC) and allotetraploid (2n = AABB, 2n = AACC, and 2n = BBCC) crop species (canola, cabbages, mustards). We used high-throughput SNP mol...
BACKGROUND AND AIMS Brassica napus (AACC, 2n = 38, oilseed rape) is a relatively recent allotetraploid species derived from the putative progenitor diploid species Brassica rapa (AA, 2n = 20) and Brassica oleracea (CC, 2n = 18). To determine the influence of intensive breeding conditions on the evolution of its genome, we analysed structure and copy number of rDNA in 21 cultivars of B. napus, r...
sclerotinia stem rot (ssr), caused by sclerotinia sclerotiorum, is believed as the most important disease of canola (brassica napus) in iran. temporal analysis of the disease epidemics was carried out by evaluating ssr in 80 fields in four locations of: gorgan, aliabad, kalaleh and gonbad in golestan province during 2006 and 2007. scouting of the fields to record disease incidence (i) and disea...
The recently published genome of Brassica napus offers for the first time the opportunity to gain insights into the genomic organization and the evolution of miRNAs in oilseed rape. In this study, 12 small RNA libraries from two B. napus cultivars (Tapidor and Ningyou7) and their four double-haploid lines were sequenced, employing the newly sequenced B. napus genome, together with genomes of it...
canola (brassica napus l.) is one of the most important oil seed crops. in order to evaluate the effects of integrated fertilization (chemical, manure and biofertilizers) on canola (b. napus variety hyola 401) yield and uptake of mineral nutrients in saline soil and water, a field experiment was conducted in randomized complete blocks (rcbd) arrangement with eight treatments in three replicatio...
Investigating recombination of homoeologous chromosomes in allopolyploid species is central to understanding plant breeding and evolution. However, examining chromosome pairing in the allotetraploid Brassica napus has been hampered by the lack of chromosome-specific molecular probes. In this study, we establish the identification of all homoeologous chromosomes of allopolyploid B. napus by usin...
Yellow-seed (i.e., yellow seed coat) is one of the most important agronomic traits of Brassica plants, which is correlated with seed oil and meal qualities. Previous studies on the Brassicaceae, including Arabidopsis and Brassica species, proposed that the seed-color trait is correlative to flavonoid and lignin biosynthesis, at the molecular level. In Arabidopsis thaliana, the oxidative polymer...
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...
In this study 36 canola genotypes from seven different species including Brassica. napus, B. rapa, B. oleracea, B. juncea, B. carinata, B. nigra and B. friticulosa were evaluated under non-stressed, moderate and sever drought stress conditions during 2011-2012 in a field experiment. The relationships among different traits were assessed. Results of analysis of variance (ANOVA) indicated high va...
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...
