Introduction
In front of you, you find the Naktuinbouw calibration book for tulip. This book may be used as guidance
for the completion of application forms, the describing of varieties or the understanding of variety
descriptions. This book can not replace the skill needed to make a variety description, but may serve as
support.
Sources used
The basis for this book is the CPVO protocol TP/115/3 which in turn is based on UPOV Guideline
TG/115/4. The application of this calibration book is based on the general UPOV principles on the
definitions and use of characteristics of variety descriptions (UPOV TG/1/3). Please also use these
sources for reference when using this calibration book.
Application methodology
The UPOV system is based on the expression of characteristics that are related to the expression
values of example varieties. In the calibration book you find two types of characteristics; visually
assessed characteristics and measured characteristics.
The value of the visually assessed characteristics can be compared with the visual value of the
expression of example varieties. In the calibration book you may find drawings or pictures to assist in the
decision on the applicable expression.
For measured characteristics this is more complicated as in many cases the value of the measurements
is depending on the (climatical) conditions of the trials. The use of example varieties in these cases is
indispensable. The same applies for those visually assessed characteristics that are prone to influence
by climate (e.g. anthocyanin coloration). In this calibration book these example varieties are only
included for the characteristics that appear in the Technical Questionnaire. Others are not included as
many prefer their own set of example varieties, but may be found in the relevant CPVO protocol.
The quantitative characteristics of candidate varieties are, in many cases compared with the measured
data of a set example varieties (e.g.plant: length). The measured data of candidate varieties and
example varieties can fluctuate from year to year due to environmental and culture conditions. But all
example varieties have a established and unchangeable description. If in year 1 the plant: length of the
example variety ‘V’ in 5 (medium) is 60 cm and candidate variety ‘A’ also has a length of 60 cm, than
variety ‘A’ is classified in 5 as well. If in year 2 the plant: length of the same example variety ‘V’ is 65 cm
( e.g. because of extreme weather) and the plant: length of candidate variety ‘B’ is also 65 cm, Variety ‘B’
is also classified in 5.
In this way the classification of candidate varieties is made independent from year-, climate- and
environmental circumstances

Number of plants for evaluation: 10

Observation: all applications
Time: When the tulip is ripe. This is the stage that the pollen from the stamens begin to become loose.
The tulips are evaluated in the closed position.
Method: Compare the color of the central part of the outer side of outer tepal with a RHS Colour Chart
and write down the RHS number, then add the RHS number in to UPOV colour group number.
Light conditions should fulfil one of the following criteria:
- Diffused light
- After a window with northern light
- Under artificial light (CIE standard daylight D 6500)
Try to avoid direct sunlight or any other situation with bright light other than mentioned above.
Photos: The photos showed how the main color is measured and the flowers with different colors.
The photo shows where the main color should be checked with the RHS Colour Chart. The photos on
the previous page, show some examples of different flower colors.

The tulips are evaluated in the closed position.
Method: Visually observe the number of colours on the outer side of the flower.
Photo: The photos display the flower with two colours. In photo above, middle, a pink tulip with a
difference in hue on the margin, this is scored as a single-colored flower. In photo above right, a red tulip
with a clear yellow base, this base colour is usually not considered as another colour.
As it is showed in photo left, lower row, sometimes it happens that the
outer tepals have irregular green parts, this green colour is not scored as a second colour. It is most
likely an interim phase between leaf and flower and probably due to the big size of the bulb or the higher
temperature. On the photo right, lower row, the green colour is scored as a second colour as it is a
variegation resulted from the genetic background.

Light conditions, under which the observations are made, should fulfil one of the following criteria:
- Diffused light
- After a window with northern light
- Under artificial light (CIE standard daylight D 6500)
Try to avoid direct sunlight or any other situation with bright light other than mentioned above.

Type of observation: visual
Visual, using; RHS Colour Chart
Number of plants for evaluation: 10
Number of observations: 1
Observation: all applications
Time: When the tulip is ripe. This is the stage that the pollen from the stamens begin to become loose.
The tulips are evaluated in the closed position.
Method: With the RHS colour chart, the colour of the marginal part of the outer side of the inner tepals is
determined. It should be taken into account that a tepals be chosen, which still retains colour and not
during growth and flowering time much light is absorbed, making colour changes may occur.
Light conditions, under which the observations are made, should fulfil one of the following criteria:
- Diffused light
- After a window with northern light
- Under artificial light (CIE standard daylight D 6500)
Try to avoid direct sunlight or any other situation with bright light other than mentioned above.
Photo: The photos show the correct position of the marginal colour on the outer side of the inner tepals.

Type of observation: visual
Scoreset: 1,9
Number of plants for evaluation: 10
Number of observations: 1
Observation: all applications
Time: When the tulip is ripe. This is the stage that the pollen from the stamens begin to become loose.
The tulips are evaluated in the closed position.
Method: Visually observe whether there is a different color on the border of the macule or not.
Photo: The circled area in the photo above left, shows the exact location on the border on the inner side
of the inner tepals. If the border of the macule shows a different colour in the form of a hue, as shown in
the photo under left, it is sufficient to indicate the main colour. Accurate colour determination by the RHS
Colour Chart is not necessary.
It is also possible that the border of the macule is absent, as in the the photo under right. In such case,
the colour of the border of the macule is absent.

Time: When the tulip is ripe. This is the stage that the pollen from the stamens begin to become loose.
The tulips are evaluated in the closed position.
Method: Visually, the number of colors of the filament is determined.
Photo: The photos are some examples of monochrome and two-colored stamens. The stamens on the
photo in the middle, are not evenly colored, but the difference is in tone, the base is light yellow and the
distal half yellow. In this case these stamen are classified as one colored (1).
