摘　　要：为促进蓝莓耐高pH种质创新,在pH5.8条件下,以增殖系数为鉴定指标对矮丛、半高从、北高丛3种类型共19份蓝莓品种耐高pH培养基能力进行评价。结果表明:蓝莓耐高pH培养基能力在不同品种和不同类别中存在差异。最终筛选出4份耐高pH培养基品种,矮丛蓝莓2份,分别是美登和野生蓝莓;北高丛蓝莓是蓝乐,半高丛蓝莓是北陆地。对培养后的增殖系数(Y)和株高(X)进行相关性分析,并建立鉴定蓝莓耐高pH培养基能力的回归方程:Y=0.29 X+3.64(r=0.67,F=13.71**),此方程可以用于耐高pH培养基的蓝莓筛选。In order to promote gremplasm resources innovation of blueberry with high pH tolerance,we evaluated the ability of19different varieties of blueberry to resist high pH medium with the proliferation coefficient as the identification index at pH5.8.The result showed that there were obvious differences in the ability to resist high pH medium between varieties and types of blueberry.Eventually,four varieties of blueberries including two short bush blueberries,Mayden and wild blueberries,the northern high bush blueberry Lanle and the semi-high bush blueberry Northern land were chosen to be tolerated with high pH.The proliferation coefficient and plant height analyzed and established of high pH medium resistance of blueberry identified regression:Y=3.64X+3.64(r=0.67,F=13.71**).
