EVALUATION OF GROWTH CHARACTERISTICS, DEVELOPMENT, YIELDAND OLEANOLIC ACID CONTENT IN Achyranthes bidentata Blume ACCESSIONS IN THANH TRI COMMUNE, HA NOI CITY

Abstract

This study evaluated 16 Achyranthes bidentata Blume. germplasm samples from various locations to select those with high yield and oleanolic acid content, a key triterpenoid for medicinal value. The experiment was established following the varietal collection survey method, with a sequential, non-replicated design at the National Research Center for Medicinal Plant Germplasm and Breeding - National Institute of Medicinal Materials in Thanh Tri commune, Ha Noi city. The dry root yield ranged from 2.11 to 4.04 tons/ha, oleanolic acid content from 1.84% to 2.74%, and active compound yield from 42.29 to 99.38 kg/ha. The NT4 sample from Thanh Tri commune, Ha Noi city, showed the highest performance with a yield of 4.04 tons/ha and 99.38 kg/ha of oleanolic acid. NT4 is considered a promising variety for further selection to develop high-yield, high-quality Achyranthes bidentata Blume.
