6. The TWO agreed to propose the following editorial correction to the text of document TGP/5, Section 6:

- • capitalize first letter and add full stop at end of sentence to read: “(If the variety is distinct, • capitalize first letter and add full stop at end of sentence to read: “(If the variety is distinct, uniform and stable.)”

7. The TWO agreed to propose the following editorial correction to the text of document TGP/7, section “Characteristics which only apply to certain varieties”:

- • delete quotation marks from state of expression to read: “(PQ) Only varieties with: Presence • delete quotation marks from state of expression to read: “(PQ) Only varieties with: Presence of hairs: Other than absent or very weak (1): Hair: color”

8. The TWO noted that the TC had agreed the proposal for revision of document TGP/5, Section 6, to be proposed for adoption by the Council at its fifty-fourth ordinary session, to be held in 2020. The TWO agreed to propose that the following changes were considered by the TC for a future revision of document TGP/5, Section 6:

Chapter: UPOV Report on Technical Examination

- • 13 to read “Testing station site(s) and place(s)” • 13 to read “Testing station site(s) and place(s)”
- • item: Date and document number of UPOV Test Guidelines • item: Date and document number of UPOV Test Guidelines
- • item: Date and/or document number of Reporting Authority’s test guidelines • item: Date and/or document number of Reporting Authority’s test guidelines

Chapter: UPOV Variety Description

- • 11 to read “Testing station site(s) and place(s)” • 11 to read “Testing station site(s) and place(s)”

9. The TWO considered the explanation to item 16 “Similar Varieties and Differences from These Varieties”, as presented in the Annex to Chapter “UPOV Variety Description”. The TWO noted there were different interpretations among participants on the sentence: “Only those characteristics that show sufficient differences to establish distinctness should be given.” The TWO agreed to invite the European Union to make a presentation on “providing information on ‘Similar Varieties and Differences from These Varieties’” at its fifty-third session.

#### Possible future revisions of TGP documents and information documents

TGP/8: Trial Design and Techniques Used in the Examination of Distinctness, Uniformity and Stability

#### Data processing for the production of variety descriptions for measured quantitative characteristics

10. The TWV, TWO and TWA considered document TWP/4/10.

11. The TWV and the TWA considered the different approaches to convert observations into notes for producing variety descriptions for measured quantitative characteristics, as presented in document TWP/4/10, Annexes III to VII, and information, if any, that could facilitate their application.

12. The TWV noted the comments provided by the European Union and Germany on the methods described in the Annexes of document TWP/4/10 and agreed to request the following additional information:

Annex III, French Method 2:

- • describe what are the variables “a” and “B” in the regression model “Y = a + Bx”; • describe what are the variables “a” and “B” in the regression model “Y = a + Bx”;
- • provide an explanation on the graphic “Example for the characteristic flowering time • provide an explanation on the graphic “Example for the characteristic flowering time of sunflower” in particular whether each blue dot in the graphic is an example variety and how the blue dots are calculated (a value per variety but calculated over years?).
- • clarify the scale of the graph. Note 10 should not be possible according to the • clarify the scale of the graph. Note 10 should not be possible according to the characteristic

Annex IV, Japanese method:

- • clarify whether the word “distance” used in the text means “width of class” • clarify whether the word “distance” used in the text means “width of class”

Annex VI, German method, slide 16:

- • clarify whether the difference between the states of expression is always the same • clarify whether the difference between the states of expression is always the same (6 cm);
- • clarify whether example varieties are taken into account. • clarify whether example varieties are taken into account.
