The first-ever inter-generic cross was successfully performed between bamboo and sugarcane by T. S. Venkatraman.
Sir Tiruvadi Sambasiva Iyer Venkataraman was an Indian botanist, agronomist and plant geneticist who specialized in the study and hybridization of sugarcane.
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.
