There is no black thorn 100 tree. D 200 is relatively new. The big tree in the picture is just a Kampong durian tree. Only D 1 Datok Nina and D 24 have very old trees as they were registered in 1935.
May be you don’t know how the 100 years blackthorn come about. Last year, I visited Sungei. Ara durian farm & the farm owner told me how they use techniques to cross breed the new blackthorn with existing old kampung durian tree of 40 years above. 3 years later the dna will inherit with the dna age of the old tree.
