党参新品种渭党3号是利用不同能区的100 ueV/u 14N重离子束，在剂量率1×1016 N+/cm2下对党参品种渭党1号进行辐照处理，按辐照诱变育种程序选育而成。该品种在区域试验中平均鲜根产量6 090.0 kg/hm2 ，较对照品种渭党1号增产14.7%；特等和一等品出成率平均44.5%，总灰分3.9%，浸出物64.7%。质量显著优于2010版《中华人民共和国药典》标准。耐寒性较强，较抗根腐病，平均田间发病率8.56%，病情指数3.61%，较对照品种渭党1号分别降低4.27和1.34百分点。适宜在海拔1 900～2 400 m，年降水量450～550 mm的半干旱及高寒阴湿区种植。

Weidang 3 is a new Codonopsis pilosula variety， using the different energy regions of 100 ueV/u 14N the heavy ion beam， the Weidang 1 is preirradiation process at a dose rate 1×1016 N+/cm2， according to the irradiation induced breeding program， the new Codonopsis pilosula variety is selected. The average yield of the varietie fresh root is 6 090 kg/hm2 and 14.7% higher than of the check variety Weidang 1 in the regional test， the principal and first-class root extractions rate is 44.5%. Total ash is 3.9%， extract is 64.7%. The quality is significantly better than the 2010 edition of the Pharmacopoeia of the people's Republic of China. The result shows that the cold resistant sex is stronger， and resistance to root rot， average field incidence ratio is 8.56%， disease index is 3.61%， 4.27 and 1.34 percent higher than of the check variety Weidang 1. It is suitable to be grown in annual precipitation is 450 ~ 550 mm at an altitude of 1 900 ~ 2 400 m， in semi-arid and high cold and shade moisture region.
