Actually, I was originally looking for this one.
http://tropicalfruitforum.com/index.php?topic=8090.msg171365#msg171365 . I got the fruit in Hong Kong and the fruit was about 1 lbs and was so sweet, it tasted like agave nectar. The regular Yellow Dragon can get fruit about the size of the ones in the video above. After some researching, I've discovered that there are at least two giant Yellow Megalanthus with slightly different Phenotype.
One of the phenotypes looks like the normal small sized fruit but just larger. It can also have less fins like the fruit from Hong Kong.
The other Phenotype is less elongated and much wider and rounder in the center of the fruit.
I currently have seedlings growing from two different varieties of giant Yellow Megalanthus. The fruit from both sources should give fruit at least double the size of the smaller Megalanthus or 1+ pound. The seedlings are small and it will be several years before I will have fruit to taste.
