Open publisher page 0 citations

Abstract

Genetic relationship of 40 maize inbred lines were analyzed by inter-simple sequence repeat (ISSR) marker.Ten primers,which selected from 59 primers,were used to amplify the maize simple,90 bands were amplified,including 81 polymorphic bands.The percentage of polymorphic bands was 90.00%.The results showed that plenty diversities existed in the maize inbred lines.Cluster analysis by UPGMA indicated that genetic similarity was from 0.65～1.00.The result revealed the genetic relationship between different maise inbred lines.All the result provide reference for to fine varieties improvement and breeding on molecular level.
