Abstract:

The development and application of biotechnology are permeating genetic breeding of grapevine as a whole. DNA markers facilitate investigations into the origins of existing cultivars and provide powerful tools for the creation of new cultivars. In particular SSR marker, is widely used in identifying grape cultivars, pedigree analysis, and constructing genetic map. DNA molecular marker-based genetic maps are accelerating grape breeding programs by permitting early selection for promising seedlings. Genetic mapping in combination with physical mapping can lead to the isolation of grape genes that control important traits. The application of technology in genetic transformation permits the targeted modification of existing grape cultivars. Therefore, biotechnology is dramatically changing the traditional methods of grapevine breeding today.

Key words: grapevine cultivars, breeding, DNA markers, genetic map, genetic transformation
