There you go again, teasing us as usual! You need to spill the beans already. Yes, everyone's still interested--BUT people will lose interest the quieter you are!
I'm still interested in finding out more about bi-colors. I also think perhaps a green gene has something to do with them, maybe green fruit or green stripe. I have a cross from a clear skin yellow and a green fruit and think there may be something besides apricot contributing. I also have a brown that I believe flip-flopped to green, maybe you can tell us more about the common genes between greens/browns (blacks.) As for your uploading problem, just use ACDSee (I prefer version 5 instead of newer versions) and run a batch resize--select all the files and resize to whatever dimension or percent of original. You can also change the compression ratio at the same time to save on the file size(s.) Tom, heaven forbid, but I was also just curious if you have a plan in place in case something ever happened to you. What happens to all your work? |

Tom, you mustn't stop posting about your tomato varieties! You're all but a legend among the cultivar pioneers, from what I've read. You've got a huge reputation to live up to, and we expect you will guide us into the future of the sustainable food movement. Potatoes are a great crop, but nothing brings smiles like a red cherry tomato! Thank you for all your efforts, and we hope you will not give up on us.

I understand your lack of time Tom, but I will continue to stalk you around the internet finding time to read what you have time to write.
I'm trying to get my head around how these blue genes fit with bicolour tomatoes. Are we talking green zebra with blue shoulders, or green zebra with coloured stripes that are more photosensitive than other areas? |

I don't have the time to do this...but my isolation at times from this fourm needs remedial action.....and some folks want my input for some reason and my response here is assuaging guilt on my part and maybe responding to questions will help me understand myself better...namely ....Parallel play is in play here with all due respect. Lots of puns, however.

MOST of the genetic stocks that have been used in research in the US were developed and conserved by public sector universities and federal government research organizations during the past, however some shift to seed saving groups and hobbyists has occurred in the last 25 years or so . So many of us in the private breeding and the research community have been subject of the 'gradual attrition, and occasional dramatic losses, of these specialized stocks' over the years. So very often.... important genetic resources were dumped before "relocation plans" could be constructed and/or because a "new stock curator" was not available . The push for GMO's have led to additional "abandonment of existing genetic stocks" and I could not be there for that continuance since I am a breeder---not a inventory house of existing stocks---although I do keep a lot of true seed of potatoes and additionally maintain many obscure clones of tomatoes from the late Victor Lambeth tomato collection, for example. I dropped off many tomato varieties in my tour of Europe last year couple with the message that new varieties of tomatoes do not need to be registered with laws that forbid anyone but registered seed growers and sellers participating. I tried to leave them with the concept that new varieties can and should come from backyards rather than from the top down. Quote:
I don't know how many times I tried to use that so-called pioneer/reputation illusion as a resume of sorts to to invite myself into a variety of non-profit or for-profit organizations to pursue further development of plant varieties. It almost appears that it is an Albatross's dilemma! Quote:

There are things we now understand better (or not!)
![]() Not everything is a single gene trait; multiple genes can work together to influence an observed phenotype, such as yield or plant shape. Turning that statement around, genes at different genomic locations can affect the same characteristic, such as fruit color or epidermal hairiness. Genes for different traits may not be inherited independently (i.e. they may be near to each other on a chromosome and tend to be inherited together). That will skew observed phenotypes from Mendelian ratios. Those are some of the things that can complicate expectations, but keep genetics interesting ![]() |

Can you or anyone answer,is it possible to separate these genes or are they *always* inherited together?

Even two halves of the same gene will occasionally be swapped between chromosome pairs and thus get inherited independently. It's all about numbers and statistics.

Does anyone know whether green fruit color in wild-type tomato species is dominant or recessive to red color from cultivated tomato? I could't find any information about the green fruit color dominance patterns in general,so any answers/links would be appreciated!

My experience is that S. habrochaites ripens to white. S. peruvianum and S. corneliomulleri ripen to purple over white.
I have F1 hybrids currently flowering from crosses between domesticated red and black tomatoes and S. habrochaites. I hope to update this thread in a couple months if they produce ripe fruit. I can document that exerted stigma is recessive, and huge/fused flower petals are dominant. Orange anther cone is also dominant. Fern-leaf and potato-leaf are recessive to S. habrochaites type leaves. |

Yes. When I am on page 3 and click on 4 or >, page 3 reloads.
When I hover my cursor over 4, it does say that page 4 offers messages 46 to 49. Odd. Now the message numbers on this page have changed. This was #41, and now it is #45. Maybe I'll be able to access page 4 now . Last edited by LDiane; October 15, 2016 at 03:41 PM. Reason: message numbers changed |
