由四川省中医药研究院药物种植研究所主持研究的“黄连选种研究”课题,于1991年8月23日在由四川省中医药研究院主持召开的鉴定会上一致通过鉴定。该项研究成果历时十三年,科研人员从选种实际出发,按植物学形态、生物学特性、经济性状、品质主成分、后代表现的一致性等,进行地方栽培类群的分离与纯化,不仅为选种奠定了基础,也为黄连的广泛开发利用提供了依据,在理论和育种实践及开发利用上都有重要意义。通过集团选择选出的纸花叶、肉质叶、革大叶等品系,增产显著,品质优良,是四川省首次选育成的黄连新品系,现累计推广面积已达283 Sichuan Province Institute of Traditional Chinese Medicine Institute of Pharmaceutical Plant presided over the study of “Coptis selection research” project, on August 23, 1991 by the Sichuan Provincial Institute of Traditional Chinese Medicine held an appraisal meeting unanimously approved. The research results lasted thirteen years, researchers from the actual selection of species, according to botanical morphology, biological characteristics, economic traits, quality of the main components, the consistency of the performance of future generations, the separation and purification of local cultivated groups, not only Laid the foundation for seed selection, but also provide a basis for the extensive exploitation and utilization of Coptis, which is of great significance both in theory and practice of breeding and exploitation. Selected by the Group of paper flowers, fleshy leaves, leather leaves and other strains, a significant yield increase, high quality, is the first time in Sichuan Province bred berberine new lines, the cumulative promotion has reached 283
