Genetically Modified!

I suspect many of the vegetables and fruits that we buy are genetically modified to be infertile. More than we are told. Else how to explain those plants which I sowed from the seeds of cucumber I bought from the market and the pinto beans (also from the market) are all grown and flowering but not producing any cucumbers or bean pods.

The only exception is the wintermelon and I have this one fruit which is about two weeks old and still growing. My garden is now almost like an overgrown jungle but has this one "fruit" - it was 16 inches long and a girth of about 18 inches! I hope it will grow till 24 inches before I have to harvest it.
