AFLP (amplified fragment length polymorphism) is a very powerful fingerprinting technology. The key of making variety fingerprints is to select specific powerful primers for each crop. A quick and effective procedure for selecting AFLP primers for rice variety fingerprinting was established as the following: (1) Choose3 or more group materials that have close genetic relations. (2) Select potential polymorphic primers from AFLP (amplified fragment length polymorphism) is a very powerful fingerprinting technology. The key of making powerful fingerprinting technology. The key of making full variety fingerprints is to select specific robust primers for each crop. A quick and effective procedure for selecting AFLP primers for variety variety fingerprinting was established as the following: ( 1) Choose3 or more group materials that have close genetic relations. (2) Select potential polymorphic primers from
