Unless I missed it, there haven't been any posts saying, "Yes, I've made crosses using precocious Poncirus." Well, I haven't either. But next spring I expect to be making some. I know that the trait is recessive, so I don't expect different results in the F1 than if I use regular Poncirus. But I'm looking toward the F2 and beyond. In those generations, I'm expecting big differences in generation time. I'll be crossing, I hope, with finger lime and kumquat as I hope they will be blooming then. It is possible, but not likely, that I'll have mandarines in blloom next year. If so, they will also be crossed. Just as I hope my precocious Poncirus will be blooming. I have aquired some precocious Poncirus from several sources, All trace back to Laaz's precocious.
