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 . In this study, the complete chloroplast (cp) genome of '18 R-1' was sequenced and analyzed to assess the genetic relationship. The size of cp genome is 153,494 bp, including one large single copy (LSC) region of 83,280 bp and one small single copy (SSC) region of 17,776 bp, separated by two inverted repeat (IR) regions of 26,219 bp. The GC content of the whole genome is 36.35%, while those of LSC, SSC, and IR are 34.12%, 29.20%, and 42.32%, respectively. The cp genome encodes 132 genes, including 87 protein-coding genes, eight rRNA genes, and 37 tRNA genes. In repeat structure analysis, 288 simple sequence repeats (SSRs) were identified. Cp genome of '18 R-1' was closely related to , and .
冬油菜‘18 R-1’（L.）是一个能在中国北方极端低温为-20 °C至-32 °C的地区存活的新品种。它与传统的[品种名称缺失]和[品种名称缺失]不同。在本研究中，对‘18 R-1’的完整叶绿体（cp）基因组进行了测序和分析，以评估其遗传关系。cp基因组大小为153,494 bp，包括一个83,280 bp的大单拷贝（LSC）区域和一个17,776 bp的小单拷贝（SSC）区域，由两个26,219 bp的反向重复（IR）区域隔开。全基因组的GC含量为36.35%，而LSC、SSC和IR的GC含量分别为34.12%、29.20%和42.32%。cp基因组编码132个基因，包括87个蛋白质编码基因、8个rRNA基因和37个tRNA基因。在重复结构分析中，鉴定出288个简单序列重复（SSR）。‘18 R-1’的cp基因组与[品种名称缺失]、[品种名称缺失]和[品种名称缺失]密切相关。
