对张宏达系统山茶属茶组植物19个种和变种,应用ISSR标记进行亲缘关系的分析。从100个ISSR引物中,筛选得到11个多态性较好的引物,ISSR反应共得到166条可重复条带,多态性条带有155条,多态位点百分率(PPB)为93.4%,分析揭示茶组植物的Nei氏遗传距离(He)为0.295 1,Shanon多样性指
A total of 19 species and varieties of the genus Camellia from Zhang Hongda system were analyzed by ISSR markers. Eleven primers with good polymorphism were screened out from 100 ISSR primers. A total of 166 repeatable bands were obtained by ISSR with 155 polymorphic bands and the percentage of polymorphic bands (PPB) was 93.4% , Analysis revealed that Nei’s genetic distance (He) of tea plants was 0.295 1, Shannon’s diversity index
