With the assumption that the D# label that tags along with a durian type is supposed to be a register number with MARDI, and that the lower the number supposedly means an earlier registration date, a durian that carries the alias D17 would mean one of the earliest durians to be good enough to be officially registered with the agricultural institute.
At least that was what I was thinking when I first came across this durian from Johor.
But the truth is that there is no D17 on the official list of registered durians with MARDI. So you’ll be excused for scratching your head on how this official-sounding name came about.
