I do have been planting papayas in my garden for the past 20 yrs. I have had this case of papayas without or very less than normal seeds. But this is an isolated case. Lately I have had the opposite problem. All the papayas I plant from store bought fruit, yield  fruits with a huge amount of seeds. The taste of these fruits is different from original store bought but this is explainable due to cross pollination.
If all the papayas give less seeds and mine give abnorbmally more,  there should be a factor which is responsible for number of seeds.

Guavas  have  pectin. By cooking them and passing through a strainer you can make guava jam. If you pass through a straining cloth you can make  guava jelly. You can get instructions on You Tube  or you contact me.
 In Brazil  in many restaurants they serve Romeu & Juliet for dessert ( A slice of guava jam  on side with a slice of cheddar or Edam cheese)  or Guava Ice Cream.

Raul could you please describe me the taste of this  fruit you have ? Does it have a big seed ?  I am asking this question because I have Couepia ruffia  whoose pulp is sweet and tastes like garbanzo flour.  I also have Couepia bracteosa, fruits are smaller in size (form and size is like that of your Couepia polyandra) outside skin is light grey in colour. Taste of pulp no good.

After the tree has given the bananas ,when you cut the stalk, you can remove the flowers from the red cover and cook the flowers. Sauté some onions, put the flowers+some grated coconut+pinch of salt and let it cook for some time under low fire.

 I have some varieties of yam in my garden. Is there any manual/book describing the varieties which could help me to classify my varieties ?

Could any member of this forum help me to identify this plant ? Are the fruits edible ?  Thanks

I still have not understood your objetives : Are you going to grow to show the varieties of citrus ? Taste is something relative - why bother if the visitor has no access to taste the fruit ? Will the visitors have a chance only to see/watch ? or have a chance to try the fruit ?
My opinion: Try and plant all varieties of citrus which will grow in your environment.

I have uvaias in my garden. To me they are sweet and have a woody taste. My uvaias  are planted in the ground and receive full blast of tropical sun. I have no problems of insects/worms attacking the fruits. The big problem with uvaias is that they ripen very fast and you have to consume the day you pick them from the ground or pluck when ripe. As such they are not sold in the markets. Personally I prefer Eugenia uniflora to Eugenia pyriformis, for taste, as a juice and to make jam.

If you liked Pitomba you should come for the Pitomba Feast  celebrated ever year for more than a year in the city of Jaboatao de Guararapes
near the Port city of Recife in Northeast Brazil.

Besides length of ripening  I think another additional factor to be taken into account is how long a mango stays ripe on your table without
getting rotten ! Compared to the local brazilian varieties found in north east Brazil ( Espada  and Rosa)  the  Haden variety brought in from Florida stays ripe for a longer time.

In northeast of Brazil where I live we get four varieties of bananas/plantains. We remove them from the tree when they change colour from green to light yellow. They are ready for consuming when they are totally yellow. Ripening is accelerated if you wrap them in paper and put them in a closed box.

Western or Eastern Ghats ?. In Western Ghats you have the rainy season (Monsoons) starting mid may to august

Was your Alphonso mango from imported seed from USA or India ? Curious to know the source/supplier
