ISTA formulated rules for Seed testing.
ISTA stands for International Rules for seed testing. The ISTA Rules are the key element of ISTA's vision to achieve uniformity in seed testing and include testing methods for seeds designated for crop or plant production.
The ISTA Rules are approved and amended at the ISTA Ordinary Meetings, based on advice from the ISTA Technical Committees. The procedures for the validation of test methods are given in the ISTA Method Validation Programme.
