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.
