Study on Genetic Diversity of Maize Inbred Lines in Karst High Elevation Mountain Area by RAPD Markers

RAPD markers technique has been used to study the diversity of maize suitable inbred lines in Karst high elevation mountainous area. The screening of the 90 random primers allowed the selection of 23 polymorphic primer used for the analysis. A total of 201 polymorphic bands were produced from the 23 selected primers. Through clustering on RAPD markers by UPGMA(Unweighed Pair-Group Method Using Arithmetic Average), Mean polymorphic information content was 0.651. Clustering analysis was conducted basing on the genetic similarity coefficient. The maize suitable inbreds were classified into seven groups.
