Analysis on genetic diversity of maize germplasm

Ying Zhang

Abstract

The genetic diversity of 383 maize (Zea mays L.) inbreds were studied by 26 SSR markers,UPGMA method was used to carry on the cluster analysis,the predominance groups of corn materials were divided and classified.The results showed that 117 alleles were detected through 26 SSR primers.The average number of alleles locus by per SSR primers were 4.5 with the range which was from 2 to 8.PIC value for each SSR locus varied from 0.371 to 0.846,with the average of 0.647.The UPGMA analysis indicated that all the inbreds from different regions were divided into six groups.The result could provide a reference for hereditary and breeding of maize.
