SELECTION OF Polygonum cuspidatum Sieb. et Zucc LINES TO IMPROVE PRODUCTIVITY AND POLYDATIN AND RESVERATROL CONTENT

Abstract

Polygonum cuspidatum Sieb. et Zucc is a medicinal plant with high medicinal value. From 03 populations of equestrian Polygonum cuspidatum Sieb. et Zucc were collected by the National Institute of Medicinal Materials in Ha Noi, Lao Cai, Hung Yen, 30 promising lines of rhizome were evaluated and selected using the individual selection method for the asexually reproduced plant has 10 elite tuber cultivars with net yield of dried ranging from 30.05 - 38.85 (tons/ha) and total polydatin and resveratrol content reaching 1.32 - 2.81 %. In particular, the CKC-23 and CKC-22 lines have a net yield of 38.85 tons/ha and 36.58 tons/ha, total polydatin and resveratrol content reaching 2.81% and 2.30%, respectively are two lines with potential in yield and quality of medicinal herbs. This result is the basis for selecting tuber cultivars with a yield of over 20 tons/ha and a total polydatin and resveratrol content of over 1.1%.
