The document discusses a study that analyzed 18 grape hybrids and 7 parents from India using 12 microsatellite markers. The goals were to confirm the hybrid nature of the progenies and construct a molecular database of the parents. Cluster analysis grouped the parents and hybrids into two major groups based on genetic relationships. Three markers (VVMD-32, VVS-29, and VVS-2) were able to confirm the hybrid nature of all progenies by detecting polymorphisms between the male and female parents that were then present in the hybrids. The study confirmed the reliability of using microsatellite markers for parentage analysis and genetic studies in grapevines.
