A research team based at Jiangxi Agricultural University has marked a notable breakthrough in ornamental rapeseed cultivation, adding five brand-new flower colors to push the total number of available distinct hues to 80. This innovation is designed to reinvigorate rural rapeseed-focused agritourism and drive more integrated, sustainable development across China’s rural regions.
Leading the project is Fu Donghui, a researcher from the university’s School of Agricultural Sciences. He explained that prior to this year’s development, the team had successfully cultivated 75 unique rapeseed colors by 2025. The five new additions expand the visual range of ornamental rapeseed varieties, opening up new possibilities for scenic agricultural attractions.
For decades, vast rapeseed fields across China have drawn millions of spring tourists every year, drawn by their iconic vivid golden yellow blooms. These seasonal floral displays have grown into one of the most popular rural tourism draws, supporting countless local small businesses from accommodation to catering. However, the universal single yellow color has long created unaddressed challenges for the tourism sector. Fu notes that the lack of visual variation can quickly lead to aesthetic fatigue for repeat visitors, shortening the seasonal tourism window and limiting long-term industry growth.
To solve this problem, Fu’s team spent years refining targeted breeding techniques. Working with pollen samples provided by a research collaborator in Shifang, Sichuan Province, the scientists used a combination of crossbreeding, backcrossing and self-pollination methods to rearrange and recombine flower color genes from a wide range of existing rapeseed materials. After years of deliberate, selective breeding, the team successfully stabilized five completely new, distinct color combinations that can be reliably reproduced for commercial planting.
The breakthrough is expected to extend the appeal of rapeseed tourism, creating more visually diverse scenic attractions that can draw visitors for longer seasons. Beyond tourism, the development of multi-colored ornamental rapeseed varieties also creates new income streams for rural farmers, supporting broader rural revitalization efforts across China by linking agricultural production with leisure tourism.
