Microsatellite based Molecular Characterization and GeneticDiversity Analysis of Maize (Zea mays L.) Inbred Lines

摘要

Molecular characterization of the genotypes provides reliable information about the extent of genetic diversity which aids in the development of an appropriate breeding program. In the present study a total of seventeen polymorphic SSR markers were used across eight maize inbreds for their characterization and discrimination. The number of alleles per locus ranged from 2 alleles (UMC-1657) to 8 alleles (UMC-1097), with an average of 4.47 alleles across 17 loci obtained in the study. The PIC value ranged from 0.46 (UMC-1657) to 0.86 (UMC-1097) with average of 0.68. The dendogram constructed using similarity coefficient values divided 8 genotypes in three divergent clusters.
