Growing Mange Tout from this years saved seed.

I grew an early crop of Mange Tout in my greenhouse and saved some seeds which I intended to sow again next season. However, my Sweet Corn which I also grew in my greenhouse is now finished and I will have space again once that's removed. I have grown Mange Tout before in my greenhouse at this time of year and got a so so crop before the weather gets dire. Does the seed I've saved need a dormant period before being sown or do you think it will germinate even tho it's this years seed? Obviously I can give it a go with nothing much lost if it doesn't germinate, it was more whether I was wasting my time and out of interest.

 

Thanks @JWK I'll give it a go and time will tell.
