Looking for information on know tobacco cultivars

What book or online resources would help me be better able to identify different phenotypes of tobacco. I grew studied in botany but focused on tropical fruit tree production and propagation. Now that I have my own land I’ve been growing a fair amount of tobacco for personal consumption and gifting. When traveling I try to visit local tobacco farms and manufacturers. I understand most cultivated tobacco are hybrids nowadays, but I see most companies rename or don’t say what cultivars they use let alone say what crosses they used to make their hybrids.

If anyone knows of a good resource of knowledge like a database or encyclopedia of known cultivars I’d be grateful.. I’d like to be able to identify the species and different characteristics.
