Ambiorix,

What do you think?

Most tomatoes show this level of anthocyanin production, quite independent of potential contamination from Indigo Rose genetics.

Even if this contamination effect did happen, it would only be an issue in plants you grew from seed collected from a plant which was cross-pollinated with Indigo Rose. A plant simply growing near Indigo Rose will have no impact on the fruit produced.

Ok, thanks, I understand the implications. Im not concerned, just found it interesting. Im a bit skeptical its not contamination as its the only fruit showing antho shoulders on the plant and there are others, and no other set fruit on any other plants in the vicinity show antho shoulders. The indigo rose was harvested a couple weeks ago so it will be interesting to see if any more antho shoulders show up without antho pollen, as you suggest is normal.

It does vary by temperature, intensity of light, and presumably other environmental factors which can impact one fruit differently than others on the same plant. The fruit skin tissue is 100% from the parent plant. The seeds in the fruit are where the genetic contamination can be.

We notice very well the contamination the following generations: the blue color grows up year by year. I have every year of the people who test my following generations and who observe the phenomenon.

You should not deny this problem because it obliges us has to change opinion and to take useful precautions.

This year, I would have a greenhouse completely protected against bumblebees.
