Abstract
Objective: To breed a new Astragalus variety and to study its standard cultivation techniques, which are high yield, good quality, disease resistance, anti-reverse with intrinsic quality in line with the standard of the Pharmacopoeia of the People’ s Republic of China.
Methods: By using the method of single plant selection,15 excellent individual plants were selected in 2003→seed period tested in 2004→strains identification tested from 2005 to 2007 → new strains comparison tested for HQZX04-04-01 in medicine period from2008 to 2010→regional tested and production demonstration for HQZX04-04-01 from 2011 to 2014→Longqi 4 was named by Crop Variety Approval Committee of Gansu Province in April,2015.
Results: A new Astragalus variety of Longqi 4( the original code HQZX04-04-01) was bred. By 3 n tests in different ecological zones, the average yield of fresh Astragalus root was 708. 9 kg /666. 7 m2,and was31. 1% increased compared with the control variety; special / first class rate was 21. 5%,30. 6%,in which were 4. 8,5. 3 percentage points higher than that of the control variety, respectively; root rot disease incidence and disease index were 25. 7%,13. 5%,in which were 2. 75,2. 17 percentage points reduced compared with control variety; intrinsic quality were as follows, the total ash was 4. 5%,the extract was 41. 0%,the content of calycosin was 0. 10%,and the content of astragaloside was 0. 076%,respectively,which superior than the 2010 edition of the standard of the Pharmacopoeia of the People’ s Republic of China.
Conclusion: A new Astragalus variety of Longqi 4 is high-yield, good-quality, disease-resistant, anti-inverse and its intrinsic quality in lines with the standard of the Pharmacopoeia of the People’s Republic of China. Longqi 4 is suitable for application at an altitude of 1 900 ~ 2 400 m, the annual average temperature of 5 ~ 8 ℃,semi-arid and cold damp ecological area of annual precipitation of 450 ~ 550 mm.
