Sorry I have some trouble with this language..
..I think that the variagated plants come true from seed by virus. The virus is the factor to change the color and the plant grow.It's extremely scarce to produce the variagated plant by pollinated..

Two years ago, my wife collected some seed of a plant..**Heliopsis Loraine Sunshine** and she eliminated all the waste..leaves,petal, etc.. the seeds was clean..
I do the same think with some others seeds(Heliopsis Loraine Sunshine) but I kept all the waste(leaves petal etc) and I wait about a month to dry.. (contamination but virus)
We planted this seeds to different place and (my wife seed's) only few seeds (1 %) grow with panached leaves..
My seeds grow with about 30-40% panached leaves..
All the seeds was collect on the same plant..
Virus was probably the good raison of this variagated plants..
Sometime you see some branch with white leaves.. it's probably insect(prick) with virus.,.
You multiply this branch by cutting,grafting or in vitro...
It' s only a theory..and I have some test to verify..

Thank you, it is true that some variegation is caused by disease, and many healthy variegates do not produce true from seed, however, there are at least a few variegated plants which do breed true from seed. I have a few examples, such as Alaska nasturtiums, and I'm wondering if there are others out there about which I'm unaware. I've never heard of a virus being the cause of variegation on Lorraine Sunshine, but I have heard from others who claim that they do produce at least some variegated offspring from seed. I'll have to look into this further. Although I would be surprised to find that it is marketed as a variegated variety that's caused by a virus rather than a mutation, it wouldn't be the first time that this has happened.

This variegated variety could be affected by a virus..and probably lot of virus could be effected différents plants..
All of my seed have be traited with composting juice made with variagated leaves.. I have some nut, ginkgo, pyrus, cherry, and different other seeds...I belive than this mutation is caused by virus and all of the seeds(variagated) could be affected be a virus..
The Alaska nasturtiums has a leave like some virose...
