Ok, I think I made my conclusion on this subject. I grafted both the Thai Dwarf and World's Best on my large Shangri La tree to do this comparison test.
Thai Dwarf has been grafted on 4/20/20
World's Best has been grafted on 8/16/20
The Results are:
- Leaves, growth pattern very similar
- Fruit size and taste, pretty much identical, can't tell the difference
- Only small difference I noticed is that the World's Best doesn't seem to have as many fruits (both gets lots) per branch as the Thai Dwarf. Could be due to 4 months difference in grafting date and also started with smaller scions of World's Best.
- Both fruits hang on the tree for a longer time than the Black Pakistan, White Pakistan, Shangri La
- My taste test results below shows what I feel are best tasting (1- best) to average: [everyone has their own preference of course]
1) Black Pakistan
2) White Pakistan
3) Shangri La
4) Thai Dwarf/ World's Best
Since I can't eat this much Thai Dwarf mulberry fruits, I have been giving them away to neighbors who have never eaten them and they all say its good. To me its just an average tasting fruit. It might be good for making jams or pies.
- When I have ripe fruits of the Tice, Red Himalayan, Silk Hope, Sangue Latte, Illinois Everbearing, I can add the rest of these to the list above.
I will post some photos I took later to show that these two are pretty much the same variety.
If I had to choose which one to grow, I would take the Thai Dwarf since it has so much more fruits than any mulberry I grow. Kids would love to pick these fruits, the branches grow long and when the fruits ripen, the branches will start to bend down so you can reach the fruits without getting on a ladder. I pick my fruits every day since it started to ripen. It looks like I will have fruits every day for 2 weeks. Picked fruits for 5 days now and still have hundreds of fruits on the branches.
If you only have space to grow one mulberry then I recommend the Thai Dwarf/World's Best. You will have lots of fruits to pick.

After the fruits are done, I can also provide cuttings as well since my tree branches will need to be cut back significantly.
