What kind of data could you have by March of next year? Seeds could take longer than that to germinate! Are you just trying to see if the crosses are possible? I've got Orinoco and velutina flowering right now, as well as musa 'Royal Purple'. 'African Red' apparently has no pollen, so it would be useless as a donor. Richard says that his wouldn't accept pollen either. If I can be of any help, let me know. I don't have any of your edible varieties though. Good luck!
