That would come down to experiment. It could be you've finally recovered an interesting set of double-recessives that were hiding in previous generations... or you've got an unexpected new cross in the mix. In the first case, I'd expect it to be pretty far along the line towards being stable already and the next generation should be much like it. (It is definitely possible to get strange things appearing in later generations, it is just increasingly unlikely with increasing generations.) In the second case, the next generation would again appear to have all sorts of things going. They would essentially be F2s and the interesting plant would have been a new ~F1.
