Solution(By Examveda Team)

The Malling Merton series is related to Apple Rootstocks.
The Malling series is a group of rootstocks for grafting apple trees. It was developed at the East Malling Research Station of the South-Eastern Agricultural College at Wye in Kent, England.
In 1912, Ronald Hatton and his colleagues rationalized, standardized and catalogued the various rootstocks.
Their first list had nine rootstock varieties, assigned the "type" numbers I - IX. The list later grew to twenty-four and the Roman numerals gave way to Arabic numerals with the prefix "Malling" or "M". From about 1917, a collaboration between East Malling and the John Innes Institute, in Merton Park in Surrey, gave rise to the Malling-Merton series, which were resistant to Eriosoma lanigerum, the woolly apple aphid.
