Abstract

The world collection of cultivated pigeonpea germplasm (13 077 accessions) assembled at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) genebank from 74 countries originating from a wide range of environments may include highly photoperiod sensitive to insensitive accessions. Screening of these germplasm accessions for their response to photoperiod is very important for well-targeted use in crop improvement. As part of characterization of germplasm, a total of 10 390 cultivated pigeonpea accessions were screened for their response to photoperiod at ICRISAT, Patancheru, Andhra Pradesh, India during 1977/78 to 1988/89. Insensitive or less sensitive accessions were identified after three cycles.
