        abstract = {Several researchers have reported a considerable degree of natural out-crossing in pigeonpea from different
environments. This paper reviews the subject with respect to the variation for natural out-crossability,
pollinating vectors, extent of natural out-crossing, isolation specifications, and the possible utilization of
natural out-crossing in pigeonpea improvement .}
