Trumpington's association with agriculture was extended in 1955, when the Plant Breeding Institute (PBI) – founded in 1912 as part of the University of Cambridge's School of Agriculture – moved to the Anstey Hall site adjoining Maris Lane in Trumpington. Here the PBI developed new plants, notably potatoes called Maris Piper and Maris Peer, a barley called Maris Otter, and a wheat called Maris Widgeon. These are now in use worldwide. The PBI was split up and privatised in 1987. In 1990 the PBI moved to Colney, near Norwich, but the reference to the Maris Lane site survives in the names of plants.
