A high density genetic linkage map for the complex allotetraploid crop species Brassica napus (oilseed rape) was constructed in a late-generation recombinant inbred line (RIL) population, using genome-wide single nucleotide polymorphism (SNP) markers assayed by the Brassica 60 K Infinium BeadChip Array. The linkage map contains 9164 SNP markers covering 1832.9 cM. 1232 bins account for 7648 of ...

Floral transition and petal onset, as two main aspects of flower development, are crucial to rapeseed evolutionary success and yield formation. Currently, very little is known regarding the genetic architecture that regulates flowering time and petal morphogenesis in Brassica napus. In the present study, a genome-wide transcriptomic analysis was performed with an absolutely apetalous and early ...

*Corresponding author E-mail : [email protected] INTRODUCTION The genus Brassica comprises an important group of cultivated vegetable and oilseed crops and have great economic importance worldwide. The cultivated species of Brassica include cabbage, cauliflower, kale, broccoli, Brussels sprouts, turnip, swede, oilseed rape, various mustards and other leafy vegetables (Hong et al. 2008). As oils...

Oilseed crops, particularly canola, Brassica napus L., and B. rapa L., are now a major part of the prairie landscape in Canada. A diverse assemblage of arthropods can be found in areas devoted to oilseed crop production, either feeding on a resource provided by the crop, or feeding on other insects that have been attracted to these areas. Some insects prefer to feed on other plants that are gro...

Effect of cover crops intercropped with pineapple (Ananas comosus) on Rotylenchulus reniformis population densities and activity of nematode-trapping fungi (NTF) were evaluated in two cycles of cover crop and pineapple. Sunn hemp (Crotalaria juncea), rapeseed (Brassica napus), African marigold (Tagetes erecta), or weeds were intercropped with pineapples. Beds planted with sunn hemp or rapeseed ...

Abstract Rapeseed (Brassica napus L.) is a typical polyploid crop and one of the most important oilseed crops worldwide. With rapid progress on high-throughput sequencing technologies reduction in cost, large-scale genomic data specific have become available. However, raw sequence are mostly deposited read archive National Center Biotechnology Information European Nucleotide Archive, which free...

Fatty acid desaturase-2 (FAD2) is a key enzyme in the production of polyunsaturated fatty acids plants. RNAi technology can reduce expression FAD2 genes Brassica napus seeds and acquire transgenic B. plants with high oleic content, but effect seed-specific inhibition on seed metabolites not clear. Here we use widely targeted metabolomics to investigate normal-oleic-acid rapeseed (OA) high-oleic...

s. Therefore, more information is necessary concerning cauliflower transplant age. CHINESE CABBAGE [Brassica rapa L. SSP. PEKINENSIS (LOUR.)]. Kratky et al. (1982) in Hawaii found no significant differences in time to maturity, individual head weight, and total yield from Chinese cabbage transplants of 3, 4, 5, and 6 weeks of age. RAPE (Brassica napus ssp. OLEIFERA VAR. NAPUS). In a 3-year stud...
