Core Viewpoint - The early blooming of the "Changhua 100" rapeseed variety is attributed to innovative breeding techniques rather than temperature changes, providing a new opportunity for agricultural tourism and economic benefits [5][7][8]. Group 1: Early Blooming and Breeding Techniques - The "Changhua 100" variety blooms in late December and has a flowering period of 100 days, overcoming the limitations of traditional early-blooming rapeseed varieties [8]. - The development of "Changhua 100" utilizes a unique double haploid induction technique combined with distant hybridization, allowing for rapid selection of varieties suitable for urban agriculture in Chengdu [8][10]. - This variety's ability to grow and flower simultaneously ensures both extended flowering periods and stable yields, addressing previous concerns about early blooming varieties being susceptible to frost and low yields [8][10]. Group 2: Colorful Rapeseed and Tourism - The research team has developed various colored rapeseed flowers, including red, purple, and white, which not only enhance aesthetic appeal but also maintain agricultural traits such as disease resistance and oil content [9]. - The introduction of colorful rapeseed is aimed at creating diverse consumer experiences, transforming traditional flower viewing into interactive tourism activities [9][10]. - The Chengdu Agricultural Expo Park attracted 400,000 visitors in the first quarter of 2025 due to the cultivation of "Changhua 100" and colorful rapeseed, generating significant economic value [9]. Group 3: Multi-functional Utilization and Economic Impact - The team is expanding the use of rapeseed beyond traditional applications to include deep processing and cultural products, such as rapeseed flower yogurt and essential oil soap [10]. - The goal is to create a comprehensive value chain for rapeseed, integrating cultivation, processing, and cultural products to maximize economic benefits [10]. - The introduction of over 40 rapeseed varieties with staggered blooming periods allows for a prolonged flowering season from December to April, enhancing the sustainability of agricultural tourism [11][12].
