摘　　要：目的:选育综合性状优良的怀地黄新品种。方法:通过85-5×北京1号杂交种子的太空诱变,并经系统选育筛选出综合性状优良的地黄新品种怀地81,对新品种与主栽品种在单株鲜质量、指标成分含量、抗病性、叶绿素和花青素含量及光合特性等方面进行了测定分析。结果:(1)单株鲜质量怀地81高于5个主栽品种且差异达到极显著水平,产量怀地81(82 353 kg/hm2)高于5个主栽品种29.7%以上;(2)不同品种地黄中梓醇的含量依次是:北京3号(1.601%)>沁怀(1.588%)>怀地81(1.314%)>金九(1.277%)>85-5(1.073%)>怀丰(0.924%),怀地81梓醇含量居中,与金九差异不显著,与其他品种之间差异达到极显著水平;不同品种地黄中毛蕊花糖苷的含量依次是:怀地81(0.096%)>沁怀(0.069%)>85-5(0.047%)>北京3号(0.035%)>怀丰(0.023%)>金九(0.022%),怀地81高于5个主栽品种,且差异达到极显著水平;(3)怀地81高抗斑枯病,中抗轮纹病,对叶类病害抗性较高;(4)怀地81叶绿素含量较主栽品种高,花青素含量适中,光合速率较主栽品种高。结论:新品种怀地81具有优良的综合性状,适宜作为怀地黄新品种推广。Objective： To breed new Rehmannia glutinosa varieties with best comprehensive properties. Methods： By space mutation of hybrid seeds of 85-5 and Beijing No. 1,after systemic breeding,Huaidi 81 with excellent comprehensive characters was screened. Fresh weight,benchmark composition content,resistance,chlorophyll and anthocyanin content,photosynthetic characteristics of the new variety and the main cultivars were determined. Results： Per plant fresh weight of Huaidi 81 was higher than those five main varieties and there was extremely significant difference between Huaidi 81 and other varieties,the yield of Huaidi 81（ 82 353 kg / hm2） was29. 7% higher than that 5 main varieties. The catalpol content of different Rehmannia glutinosa varieties ranked in the order as follows,Beijing No. 3（ 1. 601%） Qinhuai（ 1. 588%） Huaidi 81（ 1. 314%） Godden nine 85-5（ 1. 073%） Huaifeng（ 0. 924%）,the catalpol content of Huaidi 81 was in the middle,and there was no significant difference between Huaidi 81 and Godden nine,but extremely significant difference from other varieties. The acteoside content of different Rehmannia glutinosa varieties ranked in the order as follows,Huaidi 81（ 0. 096%） Qin Huai（ 0. 069%） 85-5（ 0. 047%） Beijing No. 3（ 0. 035%） Huaifeng（ 0. 023%） Golden nine（ 0. 022%）,the content of acteoside of Huaidi 81 was higher than those five main varieties,and there was extremely significant difference between Huaidi 81 and other varieties. Huaidi 81 had high resistance to Septoris digitalis,and had middle resistance to leaf ring rot,which indicated that Huaidi 81 had good resistance to leaf disease. Huaidi 81 with the highest chlorophyll content and moderate anthocyanin content,and had the highest photosynthetic rate. Conclusion： The new variety Huaidi 81 with best comprehensive properties is suitable for popularizing as a new Rehmannia glutinosa variety.
