All indeterminate types of tomatoes are perennial. They will continue growing until something kills them. They do not die on their own accord. Martin we aren't talking about that kind of perenniality. Then what kind of perenniality are you talking about? Thanks |

Perenniality as Martin has stated it, is one long growing session, over several years. As Tim is using the word, it means coming back from a climate induced kill-back, where the above ground part of the plant is destroyed.

This year I'm growing Tri-hybrid Intergenic cross; so far it looks like a regular tomato. Info: seedsaversyb.dreamhosters.com/pt_search.php?PlantType=TOMATO. So is this real or a hoax? That's what I want to find out. Also, there's a Solanum spontaneum I'm trying this year. Looks like lots of wild Lycopersicon relatives, so why so they call it Solanum? But then I'm not a botanist & anyway, I'm thinking of crossing it with some real tomato. Last year, our Belgian summer was so wet that all outdoor tomatoes succumbed to blight - all, that is, except L. parvibaccatum, L. humboldtii & L. esculentum cv Olive. I'm growing these 3 again this year, hoping to cross them & get some nice resistant outdoor stuff for our climate. |

I've grown Solanum spontaneum several times. I'm sure it is a lycopersicon species. It was sold by Chiltern Seeds, I emailed them to know about the name, but never got an answer! I find the taste to be wild - not my favorite. Also the health when grown outdoor could be better.

Couldnt it be dangerous working with nightshades this way? Many are poisonous, I wonder what such wide crosses could unlock.
Im absoulutely amazed by the possbility though.

Most plants in this family have poisonous foliage, tomatoes and peppers included. Others are grown and consumed for their poison, like tobacco. Most, but not all, fruits are safe to eat however.
In general, while everyone knows of 'deadly nightshade', not many people are poisoned and only a few species have significant amounts of poison in them. In many cases the poison can be destroyed by cooking.
This thread is mostly about tomatoes, and I don't think there are poisonous tomatoes around.

It's the leaves that are poisonous? Well I'll be darned! Some types of pepper leaves are used in some southeast Asian cuisines. I don't know much more about it though and I've never tried it myself.
By the by, the next door tobacco field seems to have problems. They actually took out about half the field and the rest is yellow, stunted, and doesn't seem to be flowering. I'm wondering if this has something to do with what we've been talking about regarding viruses and stuff?

very interesting patrick. I found a wild potatoe here o all places, but it is bitter, the tribes here ate it from time to time. but from what I find it can be pretty dangerous. Michel doesnt think its safe enough to try to breed the poison out of it. Which would make it easy for the pests, but theoretically still make it in my conditions without a drop of extra water. once I perfect a few other things though I might go back to thinking about that, and finding what involved.

Many wild potatoes are poisonous to some degree. In the Andes they would eat some of those potatoes combined with other foods or clay that would interfere with absorpion of the poison. |

Among the things I am starting next year, is to try to make a wild potatoe edible. I have a wild potatoe from 7800 feet, in heavy heavy soil, grows by itself with no care. It is slightly bitter, I know the tribes here ate it sparingly. Or its cousin anyway, who knows. |

A better question to ask from this thread is which of the solanum groups are capable of interbreeding. For example, breeders tried for years to get a fertile tomato/potato cross. It was only when cellular fusion techniques were developed in the 1970's that some success was achieved.
Solanum encompasses about 2000 recognized species. From that group, 4 are globally important food crops - Tomato, Potato, Eggplant, and Pepper. Interestingly, the tomato, potato, and eggplant exhibit high levels of graft compatibility while the pepper is more genetically distinct.
The most interesting tomatoes we can grow today are all a result of crosses between S. Lycopersicum and various closely related wild species.

in a past sse year book a member offered seeds from a tomato Xoubergine or pepperxoubergine...i have to check, is this tipe of cross possible?
best wishes

Perhaps whoever listed these has access to the results of such work. |

good to know it ,before starting to do al the possible cross... thanks a lot!
