"More" virus in the tetraploids - interesting. Well it is true that not every breeder has virus tolerance high on their priorities...
One reads of concern for plants becoming overbred (including lilies), and losing vigor and/or accentuating pathogen susceptible characteristics or things otherwise undesirable . This, all in the quest for the perfect flower. But it very well could be that there is a down side to the changes in make up of tetras, whether it be chromosome number, hormones, cell structure, etc., or all.
So you were up here for the Peony convention? A few of our Rock Garden Society members are active there. I am sure you have met or heard of Harvey Buchite, and you may have come across Shirey and Dick Friberg at the meetings. Not that you had any time to spare then, but I only live nine miles from the Arboretum. You, Moby, Wanda, Pard, and anyone here on cubits or DG are welcome to visit. There is a great little nursery between me and the arb too, Venero Gardens.
