Thanks for posting. Very interesting. I remember reading it can be used as rootstock for durian?

I also have information only from the internet that the seedlings can be used as rootstock for common durian.
The trees are not cultivated and are found deep inside the Western Ghat jungles.
Monkeys are fond of the flowers and seeds. According to the tribal people, flowers are edible and delicious.

The fruits look similar to Durio oxyleanus.

According to http://www.bioversityinternational.org/uploads/tx_news/Durio_654.pdf,
Quote
Grafting to other species : Experiments have been carried out at the Burliar
Fruit Station to graft D. zibethinus scions onto Cullenia excelsa rootstocks
(Anon. 1953b). Grafting onto Cullenia excelsa rootstocks in India has been
reported by Sundararaj et al. (1970). Tidbury (1976) tabulated results of grafting
experiments onto rootstocks of this species at the Burliar Research Station.
These results showed that approach grafts to C. excelsa rootstocks averaged
much greater growth than did grafts to D. zibethinus rootstocks. Grafting to
C. excelsa also contributed to earlier flowering. Unfortunately, no record of
actual success rates of grafts to C. excelsa rootstocks were uncovered in the
available literature.

Temperature falls below freezing, in winter, near the areas where I found the C. excelsa trees.
So, it may be the most cold hardy Durian relative on the planet!
Grafting to this rootstock may help to grow Durians in sub-tropicals and in temperate climates(of course, inside a green house)!

I'm too lazy to read the full article but if this rootstock is resistant to phytophtera rootrot it might be very usefull also in the ultra-tropics.

While Googling, I read Durio ceylanicus is a synonym of Cullenia excelsa/ Cullenia exarillata.
Though the descriptions and pictures match, some sites say that D. ceylanicus is found only in Sri Lanka!
Any thoughts?

From what I read online, my understanding is that Cullenia excelsa, Cullenia exarillata, Durio ceylanicus, Durio zeylanicus and Durio exarillatus are synonyms.

According to online sources, Wild durian fruits are much smaller than what I found in the jungle. http://commons.wikimedia.org/wiki/Category:Durio_exarillatus
The fruit shown at the start of my post weighed 0.72 kg (1.60 lb) and seeds were over 20 g (0.70 oz). The fruit just fit inside my palms held together. In fact, I found fruits larger than that on a tree! But, I was not able to get them down.  :(
Fruits shown in my previous reply (tribal boys holding a Wild durian branch with fruits) were relatively smaller. Seeds also were smaller.

If no flesh, and flowers are edible, what do they pick the fruit for? Seeds edible? Very interesting read, thank you. Did it smell as pungent as fleshy Durian?

They collected the fruits for me!  ;) I read that seedlings can be used as rootstock for common Durian.

Seeds edible?
Monkeys are fond of the seeds. So, I think the seeds will be edible roasted/ boiled.

No smell at all!

Thanks friends. I checked on Wikipedia and my Durian is identical to the pic of Durio dulcis. Wiki says it is the sweetest Durio!!! but there is nothing to eat!!!! I am waiting for my fruit to ripen and will post more details.

Dear Chandramohan,
If you have found the fruit (http://tropicalfruitforum.com/index.php?topic=16366.0) in Western Ghat jungle, it is definitely not Durio dulcis. It should be Durio exarillatus.
Let's wait for your fruit to ripe for confirmation. We are waiting eagerly to see a picture of the cut opened fruit.

One of the forum members informed me that he successfully patch-budded Durian on Wild Durian seedlings and that buds have emerged.  :)

Vipin, We found few Durian trees near Mangalore. All the fruits had aborted seeds, the biggest fruit weighed about 9 kilograms.
Next year we plan to use  Wild Durian root stocks to graft on to.

Big Brother, it is really incredible to have a Durian weighing 9kg! Kindly let us know about the taste also.
I would like a few scions in future, when my second batch of Wild Durian seedlings are ready to graft on to.

No flesh to eat. Flowers (staminal tubes) and Seeds (roasted) are eaten.
Trees are found in Western Ghat jungles of Kerala, India.

Vipin,when you are ready to graft please let me know, we will send you scions sticks. The flavor is mild, colour light yellow, firm flesh, sweet, aborted seeds, high percentage of flesh.
