Complete chloroplast genome sequence and phylogenetic analysis of winter oil rapeseed ( L.).

Winter oil rapeseed '18 R-1' ( L.) is a new variety that can survive in northern China where the extreme low temperature is -20 °C to -32 °C. It is different from traditional and .

[Effects of diverse stresses on gene expression and enzyme activity of glutathione reductase in Brassica campestris.].

A novel glutathione reductase gene (GR2) was isolated from Brassica campestris Longyou 6 by rapid isolation of cDNA ends (RACE). The full-length of cDNA of GR2 was 2073 bp, with an open reading frame (ORF) of 1692 bp. GR2 encoded a protein of 563 amino acids with a deduced molecular mass of about 60.

[Safe wintering and economic and ecological benefit of winter rapeseed in dry and cold areas of northern China].

The purpose of this study was to realize the security of safe wintering of winter rapeseed in dry and cold regions of northern China. Experiments were conducted with 18 winter rapeseed (Brassica campestris) varieties at 57 sites from 2008 to 2013 to statistically analyze the wintering rate variation of different varieties in dry and cold regions of northern China. The results showed that, the wintering rate varied from 70% to 90% during the study period in different regions, which had no significant difference between different years and varieties, and had high stability and remarkable economic benefit.

[Ecological benefits of planting winter rapeseed in western China].

To evaluate the ecological benefits of popularizing winter rapeseed planting in western China, a wind tunnel simulation test was conducted with four kinds of farmland surface, i.e., winter rapeseed, winter wheat, wheat stubble, and bare field just after spring sowing, collected from west Gansu in April.
