Hi All, it's Hippeastrum flowering season (finally)...and I always make home hybrids with whichever ones bloom simultaneous...well, also keeping in mind that red is the obliteratingly dominate color trait. At some point I'm going to have educate myself with regards to chomosomal compatibility, diploids 'n' tetraploids...'cuz at this point I just cross-pollinate and hope for the best. I remember seeing in books I've read on Hippeastrum that the author actually gave the chomosomal count of various species & hybrids...but other than that, how would I go about finding out whether a particular specie/hybrid is a diploid or tetraploid...or is otherwise genetically compatible? I'm hoping there's a Cliff's Notes version somewhere. -David
