Citrullus sexual abnomalities

[Dominic J]

Looking at the cuke website, a number of varieties are reported to have sexual abnormalities, but looking them up, I can't find any of their seeds on private seed sellers' websites or the USDA'S GRIN.

I'm talking about traits like male sterility, andromonoecy, gynomonoecy, stuff like that. Does anyone have any ideas where I may find alleles like that?

Maybe won't help, but a few years ago I had several watermelon (proto-landrace) develop with male, female, and perfect flowers. I eventually decided that it was because of stress, since it didn't show up until later in the season and it was only the plants in the "dry" area where they didn't get watered.

That's quite possible. In hops, it's well known that stress can induce female plants to yield unfertile male flowers.
