Thanks for the information! I wonder if this other Turpentine rootstock will grow any better than the other Turpentine rootstock that the Florida Nurseries have been using? The Puerto Rican Turpentine rootstock that Leo Manuel uses on some of his trees are excellent growers and extremely heavy producers on that rootstock. Leo Manuel’s Todos Santos is on PR Turpentine rootstock and that tree is loaded with fruits and does not show any signs of disease although the grafted variety(Todos Santos) has a lot to do with it.

The overwhelming majority of mangos that come out of Florida are Zill nursery trees grafted to turpentine from Costa Rica. Been that way for a long time. So this Costa Rican turpentine evidently struggles in California.
Thanks for the clarification Squam256, it’s good to know where the source is coming from.
Zands and Har, I agree. The term Turpentine is used very loosely and I brought up the point about Leo having success with the PR Turpentine rootstock in order to inform readers that not all Turpentine rootstocks perform poorly here in SoCal.
Har, I also agree with you that random Mango seedlings can perform excellent in any given area. The issue will be with the consistency of the results. In my “Growing Mango trees in Southern California” thread
http://tropicalfruitforum.com/index.php?topic=23124.0. I have been recommending that people plant a variety of different types of Mangos directly seeded into the ground in the hopes that any one of those seedlings may perform better than another seedling in a particular yard.
By planting various Monoembryonic and Polyembryonic varieties within a given yard, you are more likely to find one that performs better at that particular location. A CRFG Mango Fruit facts suggested that Polyembryonic varieties may be more resistant to Anthracnose and Monoembryonic varieties may be more resistant to Powdery Mildew. I know this is a very very broad generalization but it may have some truth to it.
I hope we will get better rootstocks that are highly productive and more disease resistant in the near future. Hopefully some of the hybrid work that Dr Ledesma is doing now will give us a new and better rootstock in the near future.
