Comparative Test on New Variety of Astragalus membranaceus(Fisch.) Bge.with High Quality and Comprehensive Analysis on Economic Characters

The study was to provide the basis for the registration and popularization of new varietyof Astragalus membranaceus(Fisch.) Bge.with good quality in Shandong Province.Traditional cultivated Astragalus membranaceus(Fisch.) Bge.was used as CK,growth period,botanical characters,plant disease resistance,yield and economic characters of new variety of Astragalus membranaceus(Fisch.) Bge.(Tai huang qi 1) in Taian and Laiwu were investigated in thrice by contrast.Tai huang qi 1 growed bloom and the growth period was delayed 9~12 days,it had regularity of hight,lower fibre,lower lateral roots,character of exterior appearance and good quality;the yield was significantly higher(P0.05) than CK,being 1 187.6 kg·666.7 m-2 in average and increasing by 12.02% than that of CK;the morbidity of incidence of disease of powdery mildew and root rot resistance decreased into 27.15% and 7.7%,respectively.Tai huang qi had long growth period,concordant economic character,good prolific-acy and strong disease resistance,which could be experimented at the provincial regional test further.
