Thailand uses the same D number as Malaysia. Thai MSW also called D197 but since they are all cut from the trees, their quality is not good. The long stem is D158 Kan Yao and the other is D123 Chanee. Kan Yao maturity period is 125 to 130 days and Chanee maturity period is 105 days. Both are cut 5 to 9 days before maturity. Thai durians are all smeared with chemical using ethene to ripen the durians. The tree dropped long stem D158 is superb. All harvest by cutting will lose their quality.😂😂
