Another one of my peruvianum x pennellii cross started flowering and this one has a curved style like pennellii.

First flower on the peruvianum x pennellii hybrid opened today.

 

Thought this might be appropriate to post again.

Some interesting information in this, thank you for sharing. They mention using a pollen mix to create a domestic x peruvianum hybrid. Would this mix be domestic and peruvianum pollen mixed together?

They also mention a tomato cyphomandra hybrid. I happen to have two seedlings of Cyphomandra corymbiflora and I sowed
hardy tamarillo hybrid (Solanum corymbiflorum x diploconos) 'Pinczow 2' a couple of days ago. Might be worth an experiment.

This is a Dutch article about ToBRFV that I translated to English


Extra measures against deliberate infection with ToBRFV
 
 
 
The NVWA announces additional measures to combat the ToBRFV virus. These are particularly aimed at illegally infecting plants with a mild variant of the virus for so-called cross-protection.

The measures are necessary because inspections by the Dutch Food and Consumer Product Safety Authority (NVWA) show that several infected farms have a higher virus pressure. This greatly increases the risk of spreading to surrounding farms. The measures focus on farms with higher virus pressure and farms that illegally infect plants intentionally with tomato brown rugose fruit virus (ToBRFV).

This treatment with a mild variant provides cross-protection against more severe variants of the virus. The NVWA reports it will take enforcement action against companies that keep, propagate, trade the virus or intentionally infect plants with ToBRFV. The NVWA already warned growers last year not to apply cross-protection.

Cross-protection not allowed
ToBRFV spreads quickly, especially at high virus pressure, and can cause damage in the cultivation of tomatoes and peppers. The virus has a quarantine status in the European Union, and 48 infected tomato farms are now known in the Netherlands. Temporary emergency measures have been in place since November 2019 to prevent the spread of the virus.

The agent used in cross-protection contains a variant of ToBRFV. Application of an agent containing a quarantine organism is not allowed. The NVWA has indications that cross-protection is still being used. During inspections on several infected farms, inspectors found the ToBRFV variant from the illegal cross-protection agent.

Enforcement action
The drug is not authorized and therefore not assessed by the Ctgb. According to the NVWA, its use is not only prohibited, it also poses risks to users and surrounding businesses. The authority reports that enforcement action will be taken against suspected companies.

The cross-protection agent contains a mild variant of the virus, according to the manufacturer. This claim is not supported by scientific evidence, reports the NVWA. The drug, like other variants of the virus, causes damage to plants. Applying cross-protection increases the virus pressure within a farm site. It therefore becomes more difficult to eliminate the virus in a greenhouse.

New enforcement investigation
Last year, the NVWA completed a criminal investigation into the suspected producer of the cross-protectant and several companies that intentionally infected their plants. The file was turned in to the Office of the Public Prosecutor. The NVWA has indications that the producer of the drug has not stopped producing and selling it and has therefore launched a new enforcement investigation.

The penalties for illegal use and illegal trade in the banned drug depend on the facts and circumstances, the NVWA says. In addition to administrative measures, the companies that do use this method of cross-protection also risk criminal prosecution.

Nice if it is really an hybrid !

I advise you to grow again the two parents as the F1 should be SI, and to try to cross it with other species too

It might not be obvious in the picture but there are multiple plants in that pot so I should be able to make F2 unless the cross is sterile but I want to try to make some crosses with other tomatoes as well.
I am not sure if it will cross with domestic tomatoes, but I have a couple of domestic x wild crosses that I could use.

Hi guys
so last year I grew Solanum peruvianum from Joseph and two different types of pennellii from ebay seller Lupinaster and I decided to try to cross them.
I grew a peruvianus plant seperate from the other plants and apllied pollen from the first type of pennellii and no fruits formed. Then I tried pollen from the other form of pennellii, this one was called thick leaved form, and this time fruits formed. I then pollinated a second peruvianum plant with pennellii pollen and this one formed 
fruits as well.
Unfortunately a mouse ate most of the fruits before I could harvest them but I had a couple of fruits left with mature seeds and decided to sow them right away. Germination was good and I overwintered them in a greenhouse that is kept frostfree.
The plants look mostly like peruvianum but I believe I can smell a bit of pennellii in them. I will know for certain later in the season when they flower and fruit if it is indeed a hybrid between peruvianum and pennellii.

Hi, a little update

The first tomatoes on the wildling plants in my greenhouse have started to ripe this week and I have been sampling them for taste. Some tomatoes tasted bad but most of the orange ones taste real nice and one orange fruited tomato seems to be a tropical fruit tasting one! I've already made some crosses with it but I want to have as much as possible pure seeds from it. The flowers are not exterted so it probably is self pollinating.

Outdoor the first fruits are maturing on my Wildling selection and Wildling crosses with Matts wild cherry and Tomatito de jalapa. First fruits of these should ripen in the next weeks.
Q and BH series is also forming fruit.

Weather has been great so there is no problems with diseases yet.

Hi Tim,
Thanks for the info, I am growing it for the first time this year because of it's earliness and supposed cold tolerance.

This is my growlist for this season

-Wildling panamorous, offspring from a phytophtora resistant plant from 2021 season. A couple plants were potato leaf, I will grow these separate from the rest.
-Wildling(Phytophtora resistant) x Matt's wild cherry F1. Planted a bunch in a large pot together.
-Wildling(Phytophtora resistant) x Tomatito de Jalapa F1. Planted a bunch in a large pot together.
-Wildling x Solanum pennellii, the wildling mom was a very wild dominant plant, it didn't take pollen from more domestic tomatoes only from pennellii. I might have pollinated it also with Matt's wild cherry xSolanum pennellii F1
-Bh-series type 1 and 2. These seeds were kindly donated to me by Nicollas, these seeds came from plants that had more resistance to late blight.
-Wildling(Phytophtora resistant x (Weight in Gold x Dwarf Champion improved F3) F2. Selected these for dwarf growth and want to select for late blight resistance. Planted these in pots and will grow them outside.

-Wildling panamorous. Planted these in my greenhouse.
-Wild Gem. Only one plant
-Weight in Gold. Planted these in my greenhouse.
-Weight in Gold x Dwarf Champion improved F4. Planted in pots outside.
-Q-series. I am not sure what to do with these yet, I will probably plant them close together outside so I'll atleast get some seeds.

-Solanum pennellii form 1 and form 2.
-Matt's wild cherry x pennellii F2
-Solanum peruvianum from Joseph Lofthouse
-Solanum peruvianum. This one self seeds outside since I grew it about 4 years ago. I'm not sure where I bought the original seeds.
-Lycopersicon peruvianum x esculentum. From ebay.
-Lycopersicon arcanum x esculentum F2. From ebay

-Imur prior beta. Should have some late blight resistance.
-Sunviva. late blight resistant
-Resibella. late blight resistant
-Vivagrande. late blight resistant
-Galahad F1. late blight resistant

Some cherries/currants;

-Frosted green doctors. In greenhouse.
-Ambrosia orange. In greenhouse.
-Amethyst Cream xl. In greenhouse.
-Pienollo x La 0417 F4. In greenhouse.
-Mexico midget
-Sara's galapagos cherry
-Matt's wild cherry
-Tomatito de Jalapa

Most of these plants will be planted outside beginning of May. Most of the ones I will grow in large pots are already outside, the weather has been pretty good recently.

Decided to buy 2 packs of Joseph Lofthouse peruvianum seeds from EFN. I grew Solanum peruvianum a couple of years ago and since then I get some volunteer seedlings every year so it seems to do well here. This year I am growing 2 strains of Solanum pennellii plus a couple of pennellii crosses I made last year, maybe I could use these to cross to Solanum peruvianum.

Solanum peruvianum
   White/purple 3/4"
   Collected from Mendocino County, California. Resistant to blight and irrigation with ocean water. Lovely flavor.

This one is interesting that it is irrigated with ocean water. Our nursery is a  couple hundred meters from the sea and the groundwater and the water in the canals here is very brackish. A tomato that could handle that water would be great. This is one of the reasons I was interested in working with Solanum pennellii because it is supposed to be salt tolerant.

He also has "Wild Tomato hybrid (F2) - Lycopersicon arcanum x esculentum".

I bought these as well. This one was bred by Lupinaster himself. I don't really know anything about arcanum but could have something usefull. Only sowed 2 or 3 seeds.

I bought some lycopersicon peruvianum x esculentum seeds from ebay from Lupinaster. I asked him where he got the seeds originally and he told me they came from Trade wind fruits many years ago and that he bred them a couple generations futher.
Does anyone have any experience with these? The only information I could find was from someone on tomatoville that it was supposed to be a natural cross.

Then the Fuyu persimmon flavor stabilization, if possible, project. Though also with that line if I have enough plants, I think I want to sacrifice one to each of the other crossing blocks. It is just too good of a flavor (if it comes back) not to spread and cross with. Alternatively, just make some controlled crosses with it!

I hope you can stabilize that taste, I want to find something similar in the Wildlings I'm growing, thats why I plan to make a lot of seeds to increase the chance to find something special.

Well last year proved blight resitance is crucial here if I want to grow tomatoes outdoors.
