主　　题：Kengyilia ISSR markers genetic variation 

摘      要：We investigated the genetic variation within 32 accessions distributed to 14 species and one variety by using ISSR(inter-simple sequence repeat)*** results showed that genetic variation was relatively higher among the accessions.A total of 593 bands were amplified by 12 ISSR primers,of which 535 bands(90.2%)were *** to 80 polymorphic bands were amplified from each prime,with an average of 44.6 *** interspecies GS(genetic similarity)value ranged from 0.430 to 0.866,and the average was *** analysis showed that all accessions could be classified into 4 groups by ISSR *** different accessions in a species were clustered together,but they had genetic variation in molecular *** was obvious interspecies genetic *** with similar morphological characteristics and from the same areas or neighboring geographical regions were clustered together and had close *** markers are useful in analyzing interspecies variation in Kengyilia.
