Hello I'm new here and I have a question that I hope will be answered.

I understand that many annual plants die after setting seeds even before first frosts.If we would to somehow make a plant unable to set seeds,say,for example making it triploid,would this effectively make it a sterile perennial plant that would just keep growing?

No, there are many more factors in play that renders a plant perennial. Just because it becomes sterile it would not be able to suddenly change its physiology.
