  Rules Amendments        
 
The 'International Rules for Seed Testing' are approved and amended at ISTA Ordinary Meetings on the basis of advice tendered by the ISTA Technical Committees, supplied in the 'Proposed Rules Changes', also available for download on this website. Each new Edition includes the latest changes which were voted on at the most recent ISTA Ordinary Meeting, and can be purchased as a whole, or only the Amendments.
 
What is new about the 'International Rules for Seed Testing'?
 
Since 2003, the International Rules is available in a binder. Each year, updates, in the form of a 'single paper collection' including additions or replacements of existing pages will be published, and can then be separately inserted into the binder. With this system ISTA is able to provide more flexibility, enabling faster updates and improvements of the Rules.
 
The Prefaces from previous Editions, as well as the lists of Amendments have been placed on the following pages.
