| 3n is a wierd situation. Triploids normally will not breed. They are the result of crossing tetraploids and diploids. Triploids often have a lot of the positive aspects of tetraploids (heavier substance, larger, fuller flowers) but to breed with them is a pain. Some people will clone a triploid and treat it with colchicine (a very volatile chemical that causes chromosomal mutation) in hopes of tetraploid or hexaploid clones that can then be bred with tetraploids or diploids. I can' think of any successful hexaploids, though. Just too much genetic gobbletygook, and the danged thing is crippled and dificult, any time I've heard of someone producing a hexaploid.
