In order to screen new Lycium chinense Miller cultivar directly used in production, general survey, gathering and selecting for wild Lycium resources at foot of Yan Mountain and Bohai Bay were carried out. And their yield, stress resistance, disease resistance, medical value and nutritional quality were identified. An excellent germplasm ‘ Changxuan No. 1’ was screened. The yield of ‘Changxuan No. 1’ was 9.5 ％ higher than that of the control ‘ Ningqicai No. 1’. The total contents of protein, amino acid and essential amino acid were increased by 23.0 ％, 5.6 ％ and 8.4 ％, respectively than that of the control. The contents of flavone, Se, Zn and Fe were increased by 21.4 ％, 150.0 ％, 75.4 ％ and 11.2 ％, respectively than that of the control.%为了筛选直接用于生产的菜用枸杞新品种,在燕山山麓及环渤海湾地区进行野生枸杞资源普查、搜集和选择,对搜集到的野生枸杞种质进行产量、抗逆性、抗病性、药用品质、营养品质鉴定,从中筛选出优异种质昌选1号.昌选1号比对照宁杞菜1号增产9.5%;粗蛋白质、氨基酸总量和必需氨基酸含量分别比对照增加23.0%、5.6%和8.4%;黄酮含量比对照增加21.4%;微量元素硒、锌和铁含量分别比对照增加150.0%、75.4%和11.2%.
