摘 要 ：延胡索Ｃｏｒｙｄａｌｉｓｙａｎｈｕｓｕｏ种内分化明显。比较研究了栽培大、小叶类型后，命名小叶类型为“多花延胡索”（小叶元胡）Ｃ．ｙａｎｈｕｓｕｏｆ．ｆｌｏｒｉｂｕｎｄａ。利用分化现象在大田选育出的纯系大叶类型延胡索有１０％左右的增产幅度。

Abstract:There are diferences between the big and smal leaf types of Corydalis yanhusuo.The big leaf type is beter and yields about10%more than the small one.By comparing the big leaf type in terms of leaf charactis-tics,in florescence and flower number,we name the small leaf one as C.yanhusuo f.floribunda.
