You've chosen one of the most common and successful forms of asexual propagation called layering. It occurs in nature and is soooo easy to copy according to our own terms. Come spring, you should be able to sever the new plantlet from the mother plant. Yes, it will be a fruit producing vine.

Don't be tempted to pull up your runner to check on progress. As a matter of fact, you should secure it in some fashion so that it doesn't come 'undone'. Also, your buckets of rich, black soil need to be watched so that they don't become waterlogged and soggy. Even the best garden soil can turn into something 'different' when put into the confines of a container. Hopefully, you put drainage holes in the buckets.

Thanks Rhizo for replyingto my question.Yes i did drill holes in the bottom sides of the buckets. Thanks again for your help.
