Molecular Maps of Plant Gemone - The detection and exploitation of naturally occurring DNA sequence polymorphisms represent one of the most significant recent developments in molecular biology, Earlier in, the techniques of preparing RFLP, RAPD, VNTR, SSR, STS (sequence tagged site), and EST (expressed sequence tag) maps were described for animals, particularly for humans, mouse and Drosophila.

The preparation of similar molecular maps in crop plants has been a priority area of research in plant biotechnology also. The utility of these maps for crop improvement programmes has been emphasized during 1980's and 1990's, so that molecular maps have already been prepared for all major crop species.

The techniques of the use of molecular markers have also proved useful for characterization of crop varieties and plant genetic resources though DNA fingerprinting. These aspects of plant biotechnology
