There is another reason to have 3N progeny, as triploids are often fast-growing, as opposed to the often slow-growing tetraploids (these are of course generalizations). In the phrag world, many of the actual tetraploids these days are plagued by ragged petal edges, some of which may stem from the oft-used tetraploid Eric Young 'Rocket Fire'. These 4N plants may still be useful for breeding, but they are obviously challenged when it comes to exhibition.Originally Posted by LJA
diploids are often impossible to come across with advanced phrag breeding--that was the problem that plagued hybrids of yesteryear, the genetic dead-end after a couple of generations. this was only overcome by the ploidy work pioneered by the late Don Wimber of the EYOF, which is why most "complex" phrag hybrids will be 3N or 4N.
