Identification of crop varieties

Identification of crop varieties:

1. Unambiguous differentiation and identification of crop varieties is essential for their registration, protection, utilization and quality control of seeds.
2. DNA fragment profiles obtained with different marker systems should provide fingerprints highly characteristic of varieties.
3. Molecular markers systems have been extensively used for identification of crops cultivars, somatic hybrids and cybrids. Genetic stocks such as somaclones and cytoplasmic male sterile lines in different crops.
