Assignment of entry numbers during plant introduction is called:
Cataloging systematizes documentation by assigning unique accession numbers to each introduced sample clearing quarantine. NBPGR uses EC prefix for exotic collections from abroad, IC for indigenous germplasm within India, IW for wild relatives and ET for transgenics. Passport information including scientific name, cultivar name, pedigree, country of origin, donor organization, collection site coordinates, morphological descriptors and quarantine clearance date entered into Genebank Information System. This accessioning prevents naming confusion, enables retrieval via searchable database, links physical storage location in medium-term module at 4C or long-term at -20C, and supports benefit-sharing under PGR regulations. Proper cataloging precedes agronomic evaluation, ensuring traceability across multi-location testing and compliance with international descriptor standards from Bioversity International. This understanding supports competitive exam preparation for NEET, GATE and CSIR NET concepts linking genotype with phenotype through molecular pathways involving transcription factors, hormones and metabolic enzymes that regulate development, adaptation and reproductive biology in applied breeding programs.
