Scope

Main technical content: 1. Sample collection: In 2017, we collected 36 samples of Codonopsis seeds from different ecological regions of the party-affiliated herb planting areas and major cultivation distribution areas (Lin County, Longxi County, Weiyuan County, Min County, and Dangchang County). The seed collection took into full consideration the ecological differences of the nursery areas, main production areas, general production areas, and administrative divisions, down to specific administrative villages, altitude, and latitude and longitude. Each sample weighed more than 500 grams. The sources of the Codonopsis seeds are listed in Table 3. **Table 3: Sources of Codonopsis seeds** **No.** **Collection location** **Latitude/longitude** **Altitude (m)** 1 Dangchang County, Licheng Town, Harong Gully (Harongkou) 104°18′47.71″E 34°12′29.84″N 21712 Dangchang County, Licheng Town, Harong Gully (Harongkou) 104°18′32.12″E 34°12′40.82″N 21853 Dangchang County, Licheng Town, Chenjia Gully (Nasi Gully) 104°16′43.65″E 34°12′57.44″N 24164 Dangchang County, Licheng Town, Zhongbaozi Village (Yali Gully) 104°16′35.84″E 34°13′48.89″N 23835 Dangchang County, Licheng Town, Zhongbaozi Village (Jianghala) 104°16′35.84″E 34°13′48.89″N 23966 Dangchang County, Licheng Town, Shangying Village 104°19′8.55″E 34°14′19.95″N 22577 Dangchang County, Licheng Town, Lvyuan Village 104°18′29.98″E 34°14′34.38″N 22218 Dangchang County, Bali Town, Shimen Village (Shimenkou) 104°20′39.46″E 34°18′22.46″N 23429 Dangchang County, Mu’er Town, Lasi Village 104°20′29.12″E 34°15′33.1″N 230410 Dangchang County, Dashe Town, Dashe Gully 104°16′35.84″E 34°13′48.89″N 238611 Dangchang County, Licheng Town, Zhongbaozi Village (Jianghala) 104°16′43.65″E 34°12′57.44″N 242012 Dangchang County, Hada Pie Town, Shanglongbu Village (Shanglongkou) 104°15′58.14″E 34°13′20.36″N 22721 Dangchang County, Aodong Tow
