Use of differential levels of mean observed heterozygosity in microsatellite loci of commercial varieties of sugarcane (Saccharum spp).

In this study, we measured the genetic diversity within and among a set of 9 commercial sugarcane varieties used for alcohol and sugar production using 17 microsatellite DNA markers. The UGSM148 and UGSM59 primers were monomorphic for all 74 sugarcane samples. The estimated proportion of simple sequence repeated (SSR) polymorphic loci was 88.23%; 17 alleles were detected. The mean gene diversity of all SSR loci was 0.7279. The
