A research team at Jiangxi Agricultural University located in the northern suburbs on Nanchang, the capital city of Jiangxi province, China, situated in the hinterland of Poyang Lake Plain, bounded on the west by the Jiuling Mountains, and on the east by Poyang Lake has created over 80 new colours of rapeseed flowers, expanding beyond traditional to include shades designed to boost rural tourism.
These engineered flowers are being cultivated in over 300 scenic areas across 233 Chinese counties to revitalize rural economies and combat tourist “aesthetic fatigue”, creating with these new rapeseed varieties with innovative colours more attractive fields.
Through hybridization, backcrossing, and self - pollination, the researchers achieved unprecedented combinations, Among the new colours are “deep pink red”, “tiger striped orange”, “metallic purple”, “lavender purple”, and “glutinous rice red”, all colours vwith more intense tones and better ornamental qualities.
Future projects include other colours such as blue and black, expanding the potential of rapeseed in agricultural tourism and also home gardening.
Key Details on the Development:
• Colour Range and Variety: The new varieties offer diverse colours, enhancing the visual appeal of farmland.
• Development Process: The team used hybridization, backcrossing, and self – pollination, sometimes screening up to 150.000 plants monthly to select the best traits.
• Tourism Impact: Demonstratins show high visitor interest, and the initiative aims to promote sustainable rural development through scenic agricultural, also known as “agritourism”.
This 12 - year research effort creates the most comprehensive coloured rapeseed germplasm resource in China, improving both the scenery and potential for agricultural income.
A researcher at Jiangxi Agricultural University, Fu Donghui, explained that this year the team developed five new colours, expanding the palette from 75 to 80. Most rapeseed flowers are yellow, which can cause aesthetic fatigue in tourist and the new colours seek to maintain the attractiveness of the fields and support the sustainable growth of the industry.
Rapeseed tourism has grown in regions such as Hangzhong, Shaanxi, Jingzhou, Hubei, Luoping, Yunnan and Wuyuan, Jiangxi. The new varieties have been tested at more than 10 rural tourist sites and the team collaborates with more than scenic areas in 233 counties to promote their cultivation.
Beyond rapeseed colours, researchers have developed fragrant oversized blooms, larger jasmine - scented flowers, dwarf potting plants, as well as lines with colourful leaves and stems have developed. This to stabilise the new colours, improve yield and resistance, and transform rapeseed and other specimens into outstanding ornamental plants without losing their agricultural value.
