DNA FINGERPRINTING OF IMPORTANT  VARIETIES OF FRUITS, VEGETABLES, ORNAMENTAL , MEDICINAL AND AROMATIC PLANTS

           

Background

 

Technically accurate methods are important in protection of new released genotypes and hybrids. Establishment of an effective molecular identification system(s) helps in the development of superior new genotypes/hybrids. Protection of plant breeders’ rights helps to stimulate investment in research and development.

 

Identification of new genotypes/hybrids/cultivars is based on morphological traits in most crops (International Union for Protection of New Varieties of Plants [UPOV]. However, these characteristics suffer from environmental effects, epistatic interactions, and other effects. Breeders look for alternative approaches to develop improved lines, including the use of molecular markers for characterization of desirable traits and genotypes. DNA fingerprinting techniques including restriction fragment length  polymorphism (RFLP), random amplified polymorphic DNA (RAPD), inter simple sequence repeat (ISSR), single nucleotide polymorphism (SNP), and simple sequence repeat (SSR) are used for cultivar identification in a wide range of species due to their high heritability and sufficient polymorphism to discriminate genotypes .The resulted barcodes, derived from the allelic variation of the microsatellite loci, clearly differentiate the cultivars under study. The barcoding representation, which is shown in  various Figures, has been generated using microsatellite markers or other types of molecular markers . This barcode representation can be used as a fingerprint profile for each cultivar as it clearly shows a unique pattern. It will further help by acting as a reference or standard. This barcode profile is a visual representation of the data, allowing easy detection of genotypic differences, thereby helping in the identification of the individual with absolute certainty.
