International Rules for Seed Testing
Edition 2009


Complete edition 2009 in two parts: Rules & Annexe to Chapter 7
(includes the 1.2.1 Amendments 2009 )

The 'International Rules for Seed Testing' are ISTA's primary instrument to promote uniformity in seed testing. The ISTA Rules have 17 sections that provide definitions and standardised methods to be used in, for example, sampling, testing seed lot quality and reporting results for international trade. The ISTA Rules are also a useful reference guide to germination conditions and methods for over 1000 species.

The 'International Rules for Seed Testing' are approved  by and amended at ISTA Ordinary Meetings on the basis of advice tendered by the ISTA Technical Committees. The Edition 2009 (effective 1st January 2009) includes the latest changes which were voted on at the ISTA Ordinary Meeting 2008, held in Bologna, Italy, June 19.

Updates, in the form of a single paper collection including additions or replacements of existing pages are published as 'Amendments' to the 'International Rules for Seed Testing', and can be separately inserted into the binder. This system enables ISTA to provide more flexibility, enabling faster updates and improvements of the Rules.
 
Additional information on seed testing can be found in various ISTA Handbooks, however, without having legal character. 

The 'International Rules for Seed Testing' includes the Annexe to Chapter 7.
