云南首次成功选育蒲公英新品种

Core Viewpoint - The successful cultivation of two new dandelion varieties, "Dianhongpu 232-1" and "Dianhongpu 232-2," marks a significant breakthrough in the breeding of highland medicinal plants in Yunnan, showcasing both medicinal and ornamental value [1][7]. Summary by Sections New Varieties - "Dianhongpu 232-1" has a height of 38-60 cm, significantly taller than common dandelions, with leaves that have a purple base and prominent reddish-purple characteristics during flowering [4]. - "Dianhongpu 232-2" has an impressive chicoric acid content of 3.10%, which is 6.9 times higher than the Chinese Pharmacopoeia standard of 0.45%, enhancing its medicinal quality [4]. Nutritional Composition - "Dianhongpu 232-1" contains an average chicoric acid content of 0.57%, exceeding the Chinese Pharmacopoeia standard, and is rich in β-carotene, vitamin C, calcium, potassium, and iron [4]. - "Dianhongpu 232-2" offers a comprehensive nutritional profile, with 100 grams of fresh leaves containing 2.08 mg of β-carotene, 1.94 mg of vitamin C, 382 mg of calcium, and 102 mg of iron [4]. Adaptability and Cultivation - Both varieties can thrive at altitudes between 1000 meters and 2500 meters, with "Dianhongpu 232-1" being able to withstand temperatures as low as -40°C [4]. - The research team has developed standardized cultivation techniques, allowing for spring sowing and autumn harvesting, with multiple harvests each year [9]. Economic Impact - The introduction of these new varieties is expected to provide farmers with new economic crop options and contribute to the development of highland characteristic agriculture in Yunnan [9]. - The successful breeding of these dandelion varieties exemplifies the utilization of local biodiversity and the development of unique plant resources, which can be further used in products like dandelion tea, health foods, and medicinal materials [7].
