In order to evaluate the potential breeding value of seleng wormwood（Artemisia selengensis
Turcz.）germplasm resources，this paper carried out identification on the main agronomic traits and nutrition
contents of 14 accessions of seleng wormwood germplasm resources．The results showed that among these 14
accessions，2 mutations A. selengensis var. selengensis and A. selengensis var. shansiensis were included．The
plant height was 31.04-53.38 cm. The internodes of aerial stems were 2.70-4.16 cm in length and 0.51-0.61 cm in
diameter．The tiller numbers of single plant were 6.47-14.01．The yield for aerial stems were 3.01-6.35 kg·m^-2 ，
and 0.26-1.08 kg·m^-2 for rhizomes．The contents of dry matter，protein，total sugar and crude fiber of aerial
stems were 7.40%-9.60%，1.83%-2.33%，0.46%-0.86% and 0.30%-0.52%，respectively．The accessions
‘Boyanghonggenglouhao-3’ and‘ Poyanghuyehao-4’ were appropriate materials for high aerial stem yield
breeding，and‘ Xiaoyebai’，‘Xiaoyeqing’ and‘ Dayeqing’ were better materials for high rhizome yield
breeding．In addition，the accession‘ Dujiangyanlouhao’ is good for strong aroma breeding because of its special
aromatic ordour．
