Morning Glories: Question about 'infertile' MG strains, 1 by Hineni

Hi all,

I keep reading about these 'infertile' or 'sterile' plants. If a plant is a clone, it doesn't produce seed, correct? If a plant produces seed, can that seed be rendered sterile by the producer, for lack of a better word? How does one know if the seed is sterile other than by trying to germinate it?

My evovulus don't produce seeds which confirms Ron's excellent knowledge.

Thanks for any feedback.
