        abstract = {The cultivation of the pigeonpea goes back to at least
3,000 years. Its center of origin is India (Vavilov 1928;
van der Maesen 1980), from where it traveled to
East Africa and, by means of the slave trade, to the
American continent. Pigeonpea is an ancient crop
as there is a mention of pigeonpea in Sanskrit and
Buddhist literature dating back to 400 BC to 300 AD
(Krishnamurthy 1991). Today, pigeonpea is widely
cultivated in all tropical and semi-tropical regions of
both the old and the new world.}
