Abstract
Protection of plant varieties is dependent upon morphological characters that are used for Distinctness, Uniformity, Stability (DUS) testing.
As an alternate method to field growing and testing of cultivars, the possibility of utilising microsatellite markers was examined in this study.
The main objective of the study was to identify a potential set of microsatellite markers for discrimination of cultivars.
Microsatellite markers extracted genetic differences between clones indicating the problem of uniformity criterion that is considered as fundamental in DUS testing.
On the contrary the set of primers that expressed uniformity across clones failed to extract the maximum difference between cultivars required to establish the distinctness.
Primers with high value of power of discrimination were found to be more appropriate for establishing the distinctness of cultivars.
Microsatellite markers were to able cluster genetically similar genotypes together that are morphologically separated into distant clusters.
