Thong Pha Phum

ทุเรียนทองผาภูมิ
Thong Pha Phum · "Durian of Thong Pha Phum district, in the mountains of Kanchanaburi, western Thailand."
Also written: Thong Pha Phum durian · Kanchanaburi GI durian · ทองผาภูมิ

Thong Pha Phum is a GI name, not a separate variety. It is Monthong grown in four mountain districts of Kanchanaburi, along the Tanaosri range on the Myanmar border. Cool nights and laterite soil are credited with flesh that smells noticeably milder than ordinary Monthong, which Thai sources describe as a durian you can eat without the smell lingering. The flesh is thick, creamy and low in fiber, with small seeds. Registered as a GI in 2022, it sells at a premium and exports in volume to China.
