Abstract

Huaidi 81, a new variety of Rehmannia glutinosa with excellent comprehensive characters, was screened by space mutation of hybrid seeds of 85-5 and Beijing No.1. The fresh weight, index composition, resistance, chlorophyll, anthocyanin and photosynthetic characteristics of Huaidi 81 and the main cultivars were determined. The results showed that: the per plant fresh weight of Rehmannia ranked in the order as follows: Huaidi 81 > 85-5 > Golden Nine >Huaifeng >Qinhuai>Beijing No.3, there was extremely significant difference between Huaidi 81 and others. The catalpol content ranked in the following order: Beijing No.3 (1.601%)> Qinhuai (1.588%)> Huaidi 81 (1.314%)> Golden Nine > 85-5 (1.073%)> Huaifeng (0.924%). There was no significant difference between Huaidi 81 and Golden Nine, but extremely significant difference between was found in Huaidi 81 and other varieties;? The acteoside content ranked in the following following order: Huaidi 81 (0.096%) > Qin Huai (0.069%) >85-5 (0.047%) > Beijing No.3 (0.035%) > Huaifeng (0.023%) > Golden Nine (0.022%). There was significant difference between Huaidi 81 and other varieties. Huaidi 81 showed high resistance to Septoris digitalis Pass and middle resistance against leaf ring rot, which indicated that Huaidi 81 had good resistance to leaf diseases. Huaidi 81 with highest chlorophyll content and moderate anthocyanin content showed the highest photosynthetic rate. All these results indicated that the new variety Huaidi 81 with best comprehensive properties was suitable for popularizing as a new Rehmannia glutinosa variety.
