Identification of Corn Germplasms by AFLP Markers

Open publisher page 1 citations

Abstract

AFLP was adopted to study 55 germplasm materials,656 bands were detected with 20 pairs of AFLP primers and 487 of them were polymorphic.On average each primer combination could be used to detect 24.4 polymorphic bands.The 55 materials were clustered into 6 groups,which were identical to the groups divided by their origins.These results showed that AFLP was conducive to analyzing the genetic diversity of corn.Further analysis of the relation of the Pioneer population of American origin to Reid and BSSS populations indicated that many materials of Pioneer populations had genetic relations to the Reid populations.
