The first-ever inter-generic cross was successfully performed between bamboo and sugarcane by T. S. Venkatraman.

In 1936, he attempted to develop a further intergeneric hybrid of sugarcane and the indigenous Bambusa arundinacea bamboo, intended to combine the height of the latter with the sugar percentage of the former.
