Blue DANGER for the tomatoes.
 

This is the continuation of a post placed in another place but which is never taken back in the list of the answers given to a comment.

I thus place the continuation in another place because I judge that this phenomenon has to be known of all the lovers of tomatoes.

[B][U]PART 1[/U][/B]


[B][U][U][COLOR="Magenta"]1) After the adventure of " pineapple blue ".[/COLOR][/U][/U][/B]


In 2010, I sowed several seeds of my OSU 01 to OSU99 and I tried some crossings with other varieties.
Next years, I noticed that some crossings had succeeded. I would show later what I obtained thanks to several testers which helped me.
From 2012, I did not realize any more crossings because I noticed that I had so many crossings realized by insects and bumblebees as those whom I tried to realize myself.
In 2013, I decided to install almost everywhere among my plants of blue tomatoes of the dwarf plants in jars and to see if I had fortuitous hybridizations.

Here are the varieties which I growed: Robin Hood and Tiny Tim.

Here are the varieties which I growed: Reinhards ' Goldkirsche, pink Olive and Idaho.
I obtained certain results in 2014 and 2015 for Robin Hood and the varieties photos of which you see.

3 different characters are present on F2 with regard to compared with F1
A) Leaves are different
B) Tomatoes are 7 times as big
C) The color of certain tomatoes are red and blue.

Remarks:
1) The blue color upset the relationship) of the characters of dominance.
2) There are 3 visible characters but how many characters are crossed here in fact. Blue appears almost everywhere!!!
3) Imagine the number of possibilities of crossings of 6 characters.
4) In 2015, I obtained identical plants in 3708AB 32inch in height.
5) And a plant of 100 inch high.

I'm sorry, but your expression of English is difficult for me to follow. My understanding of what you are saying is that you made crosses with the OSU varieties in prior years, but now you are getting blue traits in varieties you did NOT cross, and further, your non-blue plants are being "mutated" in other ways which you attribute to the blue invasion. Is this close to what you mean to say?

French is my mother language.
But you understood everything.
I have many examples to be shown.

Higher than expected cross pollination seems to be a reasonable explanation for what you see. And there might be factors that enhance the cross pollination of Blues (more pollen, better pollen viability, increased insect visits to "blue" varieties...).

The likelihood that the non-blue varieties are "mutated", however, does not make sense to me. As a biologist, I cannot think of a mechanism that would explain a non-blue to blue mutation. You aren't suggesting this, are you?

It would seem to me that crossing any varieties would result in changes throughout a plant's structure and fruit with the introduction of various different genes resulting from the cross, regardless of whether the cross involved a blue variety. For the past 3 years I have been growing dozens and dozens of varieties together, including blue ones, and I have seen no blue seepage into others. I've seen very little crossing at all from any varieties. Perhaps I don't have the number of insect pollinators causing crosses as others do, although I have bumblebees at work constantly in my tomato patches. I will pay more attention in the future.

Something that should be considered is that many other strains show low levels of anthocyanin production, without any potential of crossing to OSU (or other "blue" strains). Sepal and leaf coloration is common. In particular, sepal coloration is present in var "Tiny Tim" and appears to be derived from the Solanum pimpinellifolium parent. The genes that result in the blue color of the OSU and derived strains have homologs in basically every other wild species which modern tomatoes were bred from. These genes can assort into combinations that result in enhanced anthocyanin production ([URL]http://the-biologist-is-in.blogspot.com/2014/10/making-new-blue-tomato.html[/URL]) without any potential crossing by OSU or related strains.

All my tries with Robin Hood were compared always every year with several plants of Tiny Tim. I have never noticed any blue indication on all my Tiny Tim (no blue sepals,no blue on the skin , no blue nowhere).
I consider moreover that Tiny Tim is a variety who résist to the pollen of blue tomatoes .

[B][U][COLOR="Blue"]A) an unstable variety.[/COLOR][/U][/B]

This variety created by Tom Wagner is really unstable for several reasons:
1 °) Certain plants give rather different tomatoes since the first cluster up to the last one.
2 °) Certain indefinite plants are very big (> 100 inch) or less big (60 inch).
3 °) other plants are determined and do not exceed 40 inch.
4 °) There are even dwarf plants.
It is the reason why, I like studying this kind of instability.

A Japanese ( Scope Seeds) worked well enough on this variety. I thus got myself seeds.
I harvested the seeds of a plant and in 2015, one of my testers followed 5 plants resulting from these seeds.
3001SS gave seeds 4856AB.
4856AB gave 5016BW

The picture below is an example of the kind of segregation I found in Shadow Boxing in 2013, these were all a generation beyond the original Tom sent out. If I recall correctly, this box was missing fruit from the dwarf lines.

My opinion is that it was released as a very early generation from some wildly different parent lines. I think that is part of the problem with many of the blue lines out there, they've been released unstable in the rush to market.
