Papayas from store bought fruit seeds

[JeffDM]

I've had equal luck growing fruit bearing papaya plants from seeds bought from Aloha Seed or the University of Hawaii and seeds from papayas bought at the local grocery store.
This monster was just harvested today because it appeared to have enough yellow on it and also because it was in plain view on a plant in my front yard.
The seeds came from a Mexican papaya my wife bought at the store.  I planted seeds (5 per container) and then planned to use the plants for decoration around the yard.  What a surprise when one plant started flowering and bearing fruit.

All of my papaya during the past two years have been from seed harvested from my own fruit.  Despite my having several varieties growing, they mostly seem identical to the mother tree's fruit.  This suggests most are self-pollinated from hermaphrodite plants with relatively little crossover from tree to tree, unless visiting insects have a variety-specific preference.
