I want to try my hand at crossing a couple of varieties this year. I think I get the basic idea: \emasculate the flower, manually pollinate, and grow out; select plants that have characteristics that I want, and continue growing out the most desirable plants each generation until (if I'm lucky) I can get some to stabilize after 8 or so generations.
My grow space is (relatively!) limited; I'm up to 50 plants this year, which is probably close to my limit unless my circumstances change significantly.
How many plants do you usually have in each generation when developing a cross? Is 10 plants a big enough pool to choose the best plant to grow out? Is 5?
I was hoping to try 2 or 3 crosses at a time, while maintaining a decent amount of stable plants each year.
