Found this news article from March 2010. (Reuters) - A mutation in a single gene can turn hybrid tomato plants into super producers capable of generating more and much sweeter fruit without genetic engineering, scientists said in a study released on Sunday. www.reuters.com/article/idUSTRE62R1AZ20100329 |

It is old news. The gene involved only works in heterozygous condition so you have to have hybrid seed. Keith Mueller has a few crosses that used a parent line containing the Single Flower Truss gene.

I am in communication with Zach Lippman about getting an MTA of the processing variety in Israel with the sweetness gene. Since I am not in communication with Keith about germplasm exchanges between us...I don't know much about his program.

Tom,
You can get germplasm from TGRC that has the sft gene. LA2460 and LA2473 are listed.
There are 3 sugar affecting genes in TGRC accessions. LA4104, LA2086, and LA4082 are worth looking at. LA4082 has the introgression for high soluble solids from Zamir. It also carries a gene for extended weak internodes that is very difficult to overcome.
Just an opinion, but Sungold is a source for high sweetness as is Momotaro.

Those weaknesses you pointed out with the TGRC are but again...one of the reasons some that their material is problematic to work with. I hate to work with genes that have associated problems.
The idea of contacting Zach L. is to perhaps see if some of the problems were worked out and if the processing lines are of value by themselves or in hybrids with heirloom types. I don't know...the publicity has been out there for a while but I thought ..."Why not contact Zach?"
I have no problem finding my own sweet lines. And I have used Sungold/Sunsugar/SolidGold/etc and the Momotaro. Sometimes those lines are so far back in the pedigree, I forget that those pertinent genes from them may be in action.
But I am in no pressure from folks to release lines, therefore most folks have no idea what I have in my breeding materials. Even the most interested of visitors only sample a handful of varieties.
Since the topic "Mutant gene increase tomato production" I was curious enough to want to get more detail from Zach Lippman.

on sweetness... my sweetest tom this year was by far the black cherry.

on the sft gene wouldn't most comercial hybrids contain this gene? they were bred for production right?

I am hoping to get more detail from Zach L.
