Keith- There are a few varities of bananas that do produce a few viable seeds in a bunch of fruit when pollinated with viable pollen. These seeds are isolated, planted and grown to maturity to yield (hopefully) a new and better variety. One of the female plants used in a lot of the breeding work done at FHIA employs a variety called "Highgate". It is a mutant of Gran Naine if I remember correctly. There is a pretty good article about the process at the link below.

Here is a link that might be useful: Here's the link ....

Thanks GAtrops for your reply much appreciated, I done a search of G W and came across RE:Musa williams hybrid Posted by banyan on Sun, Jun 19,05 reading this along with your letter and link was just what I was after, it filled in the gaps. We had for years a very tall big variaty with quite large bunches but the kids wouldn't eat them as they were quite starchy, so we ripped them all out and planted from what I was told Cavendish and Dwarf Cavendish which came from East Temore many years ago and the kids love them. Then about four years ago I got a variaty off a mate which he called hybrid I suppose this is what banyan refers to as williams hybrid, we have grown some massive bunches off of this variaty and taste just great. Thanks again for your help, Keith.
