PREFACE
Descriptors for Mango (Mangifera indica L.) is a revision of the original publication of
the International Board for Plant Genetic Resources (IBPGR 1989). The descriptors’
numbers given in the original descriptors list are given in parentheses in the present
descriptors list against respective descriptors for cross referencing purposes. The revised
Descriptors for Mango is based on the work of a team of experts consisting of Dr Alberto
Carlos de Queiroz Pinto, Dr Richard J. Campbell, Dr (Ms) Rachel Soto, Dr S. Rajan, Dr
M.R. Dinesh  and Dr Bhag Mal. The development of this descriptor list was coordinated
by Dr Bhag Mal. A draft version prepared in the internationally accepted IPGRI format
for descriptor lists was subsequently sent to a number of international experts for their
comments and amendments. A full list of the names and addresses of those involved is
given in ‘Contributors’.
IPGRI encourages the collection of data for all five types of descriptors (see Definitions
and Use of Descriptors), whereby data from the first four categories – Passport, Management,
Environment and Site and Characterization – should be available for any accession. The
number of descriptors selected in each of the categories will depend on the crop and
their importance to the description of the crop. Descriptors listed under Evaluation allow
for a more extensive description of accession, but generally require replicated trials over
a period of time.
Although the suggested coding should not be regarded as the definitive scheme, this
format represents an important tool for a standardized characterization system and it is
promoted by IPGRI throughout the world.
This descriptor list provides an international format and thereby produces a universally
understood ‘language’ for plant genetic resources data. The adoption of this scheme for
data encoding, or at least the production of a transformation method to convert other
schemes into the IPGRI format, will produce a rapid, reliable and efficient means for
information storage, retrieval and communication, and will assist with the utilization of
germplasm. It is recommended, therefore, that information be produced by closely
following the descriptor list with regard to ordering and numbering descriptors, using
the descriptors specified, and using the descriptor states recommended.
This descriptor list is intended to be comprehensive for the descriptors that it
contains. This approach assists with the standardization of descriptor definitions.
IPGRI, however, does not assume that each curator will characterize accessions of
their collection utilizing all descriptors given. Descriptors should be used when they
are useful to the curator for the management and maintenance of the collection and/
or to the users of the plant genetic resources. However, highly discriminating descriptors
are indicated as highlighted text to facilitate selection of descriptors and are listed in
Annex I.
viii Mango
Multicrop passport descriptors were developed jointly by IPGRI and FAO, to
provide consistent coding schemes for common passport descriptors across crops. They
are marked in the text as [MCPD]. Please note that owing to the generic nature of the
multicrop passport descriptors, not all descriptor states for a particular descriptor will
be relevant to a specific crop. In Annex II, the reader will find the ‘Collecting form for
Mango’ that will facilitate data collecting.
Any suggestions for improvement on the Descriptors for Mango will be highly
appreciated by IPGRI.
Definitions and use of the descriptors 1
DEFINITIONS AND USE OF THE DESCRIPTORS
IPGRI uses the following definitions in genetic resources documentation:
Passport descriptors: These provide the basic information used for the general
management of the accession (including registration at the genebank and other
identification information) and describe parameters that should be observed when
the accession is originally collected.
Management descriptors: These provide the basis for the management of accessions
in the genebank and assist with their multiplication and regeneration.
Environment and site descriptors: These describe the environmental and site-specific
parameters that are important when characterization and evaluation trials are held.
They can be important for the interpretation of the results of those trials. Site
descriptors for germplasm collecting are also included here.
Characterization descriptors: These enable an easy and quick discrimination between
phenotypes. They are generally highly heritable, can be easily seen by the eye and
are equally expressed in all environments. In addition, these may include a limited
number of additional traits thought desirable by a consensus of users of the particular
crop.
Evaluation descriptors: The expression of many of the descriptors in this category
will depend on the environment and, consequently, special environmental designs
and techniques are needed to assess them. Their assessment may also require complex
biochemical or molecular characterization methods. These types of descriptors include
characters such as yield, agronomic performance, stress susceptibilities and
biochemical and cytological traits. They are generally the most interesting traits in
crop improvement.
Characterization will normally be the responsibility of genebank curators, while
evaluation will typically be carried out elsewhere (possibly by a multidisciplinary team
of scientists). The evaluation data should be fed back to the genebank, which will
maintain a data file.
Highly discriminating descriptors are indicated as highlighted text.
The following internationally accepted norms for the scoring, coding and recording
of descriptor states should be followed:
(a) the Système International d’Unités (SI) is used;
2 Mango
(b) the units to be applied are given in square brackets following the descriptor name;
(c) standard colour charts, e.g. Royal Horticultural Society Colour Chart, Methuen
Handbook of Colour, or Munsell Colour Chart for Plant Tissues, are strongly
recommended for all ungraded colour characters (the precise chart used should be
specified in the section where it is used);
(d) the three-letter abbreviations from the International Standard (ISO) Codes for the
representation of names of countries are used;
(e) many quantitative characters, which are continuously variable, are recorded on a 1-
9 scale, where:
1 Very low 6 Intermediate to high
2 Very low to low 7 High
3 Low 8 High to very high
4 Low to intermediate 9 Very high
5 Intermediate
is the expression of a character. The authors of this list have sometimes described
only a selection of the states, e.g. 3, 5 and 7, for such descriptors. Where this has
occurred, the full range of codes is available for use by extension of the codes given
or by interpolation between them, e.g. in Section 10 (Biotic stress susceptibility), 1
= very low susceptibility and 9 = very high susceptibility;
(f) when a descriptor is scored using a 1-9 scale, such as in (e), ‘0’ would be scored
when (i) the character is not expressed, and (ii) a descriptor is inapplicable. In the
following example, ‘0’ will be recorded if an accession does not have a central leaf
lobe:
Shape of central leaf lobe
1 Lanceolate
2 Elliptic
3 Linear
(g) absence/presence of characters is scored as in the following example:
Terminal leaflet
0 Absent
1 Present
(h) blanks are used for information not yet available;
(i) for accessions which are not generally uniform for a descriptor (e.g. mixed collection,
genetic segregation), the mean and standard deviation could be reported where the
Definitions and use of the descriptors 3
descriptor is continuous. Where the descriptor is discontinuous, several codes in the
order of frequency could be recorded, or other publicized methods can be utilized,
such as Rana et al. (1991), or van Hintum (1993), that clearly state a method for
scoring heterogeneous accessions;
(j) dates should be expressed numerically in the format YYYYMMDD, where
YYYY - 4 digits to represent the year
MM - 2 digits to represent the month
DD - 2 digits to represent the day

PASSPORT
All descriptors listed under Passport, belonging to the multicrop passport descriptors
category, are indicated in the text as [MCPD].
1. Accession descriptors
1.1 Institute code [MCPD]

This number serves as a unique identifier for accessions within a genebank collection,
and is assigned when a sample is entered into the genebank collection. Once assigned,
this number should never be reassigned to another accession in the collection. Even
if an accession is lost, its assigned number should never be re-used. Letters should
be used before the number to identify the genebank or national system (e.g. IDG
indicates an accession that comes from the genebank in Bari, Italy; CGN indicates
an accession from the genebank at Wageningen, the Netherlands; PI indicates an
accession within the USA system).

ACKNOWLEDGEMENTS
IPGRI wishes to express its most sincere thanks to the authors and warmly acknowledges
the contribution of all the mango experts around the world who helped directly or
indirectly in the development of the revised Descriptors for Mango (Mangifera indica L.).
IPGRI also wishes to place on record its sincere thanks to the authors and reviewers of
the Descriptors for Mango originally produced by the International Board for Plant
Genetic Resources (IBPGR) in 1989 which were used as the basis for developing the
revised descriptors.
Dr Bhag Mal of IPGRI-APO coordinated the development and review of this publication.
Ms Adriana Alercia supervised the production of the text up to the publication stage
and provided scientific and technical expertise. Ms Patrizia Tazza designed the layout
and the cover.
