Anybody here a hop breeder/have Greater experience with hops?

I got interested in growing and breeding my own hops but I am having trouble finding hop specific information. I know the Greater community is quite active in hop breeding so I thought I would try to reach out here. <br><br>So I am starting with US Tettnang. I have two different plants with the same name that aren't phenotypically identical, so I will try to cross them and then grow out a few generations to see if I can stably fix any desirable traits. <br><br>I am having trouble finding information in the Greater community about how to breed hops. I know that hops are dioecious, meaning male and female cones produce different sexes. I haven't seen any male cones on my two plants, but I have seen male cones on my Cascade hops. <br><br>I am assuming that hops are cross pollinated, but is it possible to self pollinate?<br><br>What are Greater's thoughts on hop breeding? What desirable traits should I be selecting for?<br><br>Should I be using seeds or cuttings/layering in a breeding program?<br><br>Any advice on how to produce male cones?<br><br>Any advice on how I might propagate a given plant?<br><br>Any information about how to manually pollinate would be useful as well. <br><br>Any Greater wisdom would be greatly appreciated.
