ISTA

• is striving for uniformity in seed testing

• publishes the worldwide harmonized ISTA Rules providing high standard sampling and testing methods

Thus, ISTA is a standard setting body.

What are ISTA´s strategic goals regarding advanced technologies?

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 4

ISTA´s Strategic Plan 2016 – 2019

“ISTA is the leading international organization in developing and publishing

sampling and seed testing methods for trade, national and international

regulations, export and import.”

1. Goal: Develop scientifically sound rules and methods for seed

sampling and testing that meet the needs of the seed sector

Planned actions:

1. …

2. Strengthen the ‘basic’ tests of purity, other seed determination, moisture

and germination including developing methods for new species.

3. ….

4. Develop and implement new tests based on new technologies.

ISTA´s Strategic Plan 2016 – 2019

4. Goal: Strengthen the science and technology underpinning ISTA

to support innovative research and to link scientific developments

and applications in seed sampling and testing, to allow the

requirements of the seed sector to be met

Planned actions:

1. …

2. Encourage the application of new technologies, where appropriate, in

seed sampling and testing, to increase efficiency and meet the needs

of stakeholders

3. …

Thus, ISTA wants to include new technologies in ist standard.

Our proposal for ISTAs further actions

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 10

ISTA should

• define performance criteria for new technologies in cooperation of

ECOM, TCOMs and technology providers

• adapt the ISTA Rules where necessary to include new technologies in

classical testing methods.

Machine testing is always an option, not a requirement!

• provide guidance for technology companies, seed testing laboratories,

accreditation procedures and also certification systems.

• start with OSD

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 11

Machine testing in the ISTA Rules 2018 for producing results to be reported 1. Automatic seed sampler

2.5.4.4 Sampling from the seed lot ... Automatic seed samplers must be approved by the ISTA seed testing laboratory according to the “Protocol for the approval of automatic seed samplers” as approved by the ISTA membership and published on the ISTA website.

2. Seed blower 3.5.2.5. … For blowing samples, set the seed blower to the optimum blower setting, obtained with the ISTA uniform calibration sample or the anemometer (see 3.4.2.1).

3. Moisture meters: detailed calibration procedure 9.2.1.1 The object is to prepare check samples to be used for the calibration of moisture meters, and to check the calibration of moisture meters.

Why OSD?

- only identification and documentation

- no separation of other seeds required

- no inert matter identification and separation required

- object of the method in the current Rules can stay unchanged

- non-destructive, parallel testing with the same sample is possible

- principles of performance criteria and approval procedures are obvious

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 13

Example for decisions to be made: How to determine a minimum detection rate?

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 14

How to determine a minimum detection rate in OSD? Correct detection of 100 % of impurities or at least as good as a seed analyst in an ISTA accredited laboratory? Research project: Analysis of 1656 OSD test results from 27 ISTA proficiency tests, grouped in easy, moderate and difficult impurities. Mean detection rates in ISTA accredited laboratories: easy impurities: 91 % moderate impurities: 76 % difficult impurities: 36 %

What is ISTA´s standard for the detection rate,

100 % or 91 % or …

?

and how should a system be tested against the standard

?

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 16

Partners to work on integrating new technologies in classical seed testing methods 1. Relevant technical committee = Purity Committee (PUR)

2. ECOM WG „Science and Technology“

3. Rules Committee (RUL)

4. Advanced Technology Committee (ATC)

as expert group and connector to the technology providers

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 17

Do the aims of the ATC reflect this demand?

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 18

Aims of the ATC as given on the ISTA Web site: 1. Be a bridge between the Research and Development World and the other TCOMs of

ISTA. 2. Collect and interpret data and opinions on “advanced” technologies. 3. Provide information on “advanced” technologies to the ISTA community 4. Chair or participate in research/tests of “advanced” technologies in cooperation with

other TCOMs and/or act as reviewers. 5. Formulate views on ongoing or future technological developments (e.g. nano-

technology, micro electronics etc.) from a seed testing perspective to aid the ISTA organization.

Note: ATC will NOT aim at developing “ISTA approved” or “ISTA advised” technologies. ATC will NOT aim at producing proposals for the ISTA Rules.

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 19

Our proposal

The aims of the ATC should include explicitly the active support of the relevant TCOMs in their work on • integrating new technologies in classical testing

methods

• implementing them in the ISTA Rules

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 20

Our motion for voting

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 21

We ask the membership to discuss and vote about the following motion (see Document OGM18-08)

The members at the OM2018 ask the ECOM together with the relevant TCOMs: (1) to present a Rules Change Proposal for the inclusion of image

analysis systems in Other Seed Determination at the OM2019 for voting,

(2) to develop an action plan for the inclusion of new technologies in other classical seed testing methods and to present this action plan at the OM2019,

(3) to include the Advanced Technology Committee (ATC) in this process and to adapt its objectives accordingly.

2018-06-15 ISTAs position on integrating advanced technologies in classical seed testing methods 22

Our contributions for the next steps

we are prepared to become members of the WG

we will support the working group in getting started

we offer to host a meeting of the working group in Sept./Oct. 2018 in Hohenheim or Karlsruhe, Germany to

summarize and evaluate the work of the partners done so far

finalize the draft of the action plan

prepare the Rules Proposal for voting in Hyderabad 2019
