Study on the Selection of Germplasm Resource Medicinal Pueraria lobata

By field collection and introduction used to collect the 36 germplasm resources of Pueraria lobata,through planting test and biological properties investigation,the yield,pharmaceutical ingredients(puerarin,total flavonoid content) and starch content were mensurated,to medicinal resources Pueraria lobata of 2 years old from the medicinal value and economic efficiency was evaluated.The results showed that the yield and puerarin,total flavonoid content of Hengfeng No.3 medicinal Pueraria lobata and Zhouzhi No.35 Pueraria lobata were higher,its yield were over 4 000 kg/667m2,puerarin content were over 2.5%,the total flavonoids were all above 5.5%,starch content more than 10%,reaches the wild medicinal content of puerarin in Pueraria lobata level,is worthy of further breeding research,standardize cultivation techniques and promotes the use of two excellent varieties of medicinal Pueraria lobata.
