Introd. t'on Table 1. Numbers of accessions in the world collection of pigeonpea at ICRI-
Passport information, consisting of accession identifiers, information on
origin, location, etc.. are of critical importance in the predictive value of
accessions. However. these data are mostly incomplete for germplasm
assembled from other centers. The world collection of pigeonpea conserved
at ICRISAT gene bank now ,crnsists of II 034 accessions from 52
countries (Table I). From this 3134 accessions have been co!lected in
various expeditions carried out by ICRISAT. Comrlete passport information
is available for these accessions. The data sheet used in collecting
field data is included on page xv. The computer-based catalog has seven
passport descriptors, the data on which is presented in this catalog. A
major portion of the world collection has been evaluated and the summary
of data is presented in a companion volume ICRISAT Pigeonpea
Germplasm Catalog: Evaluation and Analysis'.
Source of the Germplasm
The initial collection obtained by ICRISAT comprises the germplasm
assembled bv the former Recional Pulse Improvement Project(RPIP). a
joint project of USDA. India. and Iran. When RPI P was phased out in
1970. sets of this collection remained at the Indian Agricultural Research
Institute (IARI). Regional Station at Rajendranagar. near Hyderabad,
and several agrtcultui al universities in India. In 1973-74 this material was
sent to ICRISAT from these centers. R PI P had also stored one set at the
National Seed Storage Laboratory. Fort Collins. Colorado. USA. This
material was sent to Puerto Rico and then to ICRISAT. Many of the
accessions in the RPlPcollection have died. Data on the precise origin of
many of the accessions are not available.
We soon realized that this collection was far from complete. Based on
the center of diversity, crop statistics and representation in the collection.
priority areas for collection were identified in consultation with national
and international pigeonpea scientists and the International Board for
SAT by country on ! Jan 1988.
