Breeding New Micro Tomatoes

A while ago a very generous person gave me some seeds from a miniature dwarf variety of tomato called Micro Tom.  I am very fond of this variety and am slowly building up numbers of seeds and distributing them to other growers.  This variety carries several miniaturising genes which mean that it only grows a tiny plant less than 10cm tall, this tiny plant can produce a small number of cherry tomatoes.  These cherry tomatoes taste ok and I believe the plants are meant to carry some genes for resistance of various diseases.

Breeding vegetables is enjoyable, but too often progress is slow due to only being able to grow one generation per year.  Creating a new variety of tomato often takes 5 to 10 years or more!  Breeding micro tomatoes can be a lot faster.

In any breeding endeavor the lack of space is always an issue.  After selling the property I no longer have the luxury of space which makes the problem worse.  This has started me thinking a lot more seriously about breeding a few new types of micro tomato by using Micro Tom or another micro tomato as one of the parents.  While I am trying to build up numbers of Micro Tom seeds and distribute them I am also using a small number in breeding projects.

Micro Tom Tomatoes are good, but they could be better
Micro tomatoes have very short life cycles so several generations can be grown per year.  They are often used in studies as a model organism due to their short life cycle.  From planting the seed to harvesting the fruit and planting that seed takes a little over 3 months.  I can potentially grow 3 to 4 generations a year, this means creating a new variety can take as little as 2 years (but probably a bit more than that).

Micro tomatoes take up a small fraction of the space of a regular tomato which allows for more plants to be grown in a small space.  Growing more plants means faster progress.  Space is always limiting when breeding new vegetables, even if I had acres of greenhouse space I could always use more to create more varieties a lot faster.

People overseas are breeding many new types of micro tomatoes, unfortunately we have no access to them in Australia as importing tomato seed legally is expensive and difficult.  To that end, if we are to have better micro tomatoes then someone in Australia will need to breed them.

Micro Tomatoes

Someone should breed better micro tomatoes
Micro tom, while cute as a button, is not the tastiest tomato in the world.  It is not bad, but it is not great either.  Someone should breed a tastier micro tomato in Australia.

Micro tom, while reasonably productive, could be a lot more productive.  Even though it takes up such little space it would be nice if it were more productive.  Even though it grows and crops well in a small cup of soil I still think the more productive the better.  Someone should breed more productive micro tomatoes in Australia.

Micro Tom grows cute red round tomatoes.  While this is lovely it would be nice to have more variety, apparently there is a small range of various colours and shapes of micro tomato fruit overseas.  Someone should breed several shapes/colours of micro tomatoes in Australia.

Micro Tom can and will grow at any time of year if protected from frost and many people overseas grow them indoors over winter.  Unfortunately if the temperature is too low it can not pollinate properly and can not produce fruit.  While this is only an issue in a small number of places that get cold enough for this to happen it is still an issue.  Someone in Australia should breed micro tomatoes that are more productive in colder temperatures.

One truss with lots of flowers, this would be a good cross for Micro Tom

Some micro tomato breeding ideas
Here are some of my micro tomato breeding ideas.  I have started some of these projects and am several generations through them with plans of releasing some of them soon, others I do not even have the other parent to make the first cross.

Different shaped micro tomato, everyone seems to love roma shaped tomatoes for some reason, so I have started to make a micro roma tomato.  It looks good and tasted great, it is not as productive as it should be but that can be fixed.  When it is more stable and perhaps a bit more productive I may try to sell the seeds through my for sale page.

Micro Roma tomato - the best tasting micro tomato so far

Multiflora tomatoes produce hundreds of flowers per truss, it would be great to have a multiflora micro tomato.  This will increase the productivity vastly making micro tomatoes more than an edible novelty and convince more people to grow them.  This is proving more difficult as the low percentage of leaf area of the micro tomatoes makes creating a tasty multiflora micro tomato a bit of a challenge.  I dont just want a productive micro tomato, I want it to taste good too.  It will happen, it will just take a little longer.

Finding the balance between lots of fruit and tiny plant, this micro tomato is under 9cm tall

Different coloured micro tomatoes are fun and pretty.  While getting the colours in is easy, getting a better tasting coloured micro tomato is the tricky part.  There is little point having an amazing looking micro tomato that does not taste great.  Green when ripe tomatoes tend to taste the best but people tend to shy away from them so I may concentrate on other colours to begin with.  Yellow, tangerine or stripey are always favourites, black (muddy brown) and high anthoycyanin lines are also options.  I dare say I will produce a few different things over the next few years.

Having tomatoes in the midst of winter is great.  Cold weather can prevent pollination in tomatoes.  I would love to one day grow a parthenocarpic micro tomato that can set fruit in cooler weather if protected from frost.  The genes here are a little tricky to work with and I dont have any parthenocarpic tomato varieties to use as parent stock so I have not yet started this project.

Breeding tastier micro tomatoes is interesting as growing conditions play a part in taste.  Different people have different ideas of good tasting tomatoes.  Taste is always going to be one of the traits I want in micro tomatoes.

Breeding new micro tomatoes would be simple and fast if we had access to many types of micro tomatoes with a wide array of genes, but in Australia we dont have access to many at all.  Things go a lot faster if the other parent is a dwarf tomato, but there are so few dwarf tomatoes in Australia that sometimes a regular tomato has to be used.  Luckily it is pretty obvious early on as to which seedlings are micro tomatoes and which are not so culls can be made while the plants are tiny seedlings.


Where to get micro tomatoes
When I have stabilised a few good lines I plan to name them and sell their seeds.  I will most likely list them on my for sale page when they are ready.  This probably wont be for a while yet as I do not have a garden or yard at the moment so progress is slow as everything is growing in pots and most of my seeds are stored away for the moment.

Moving to town

Recently we have moved to town.  We had to sell the property for a number of reasons.  I will miss a lot of things about the property but unfortunately selling was the right thing to do at this point in time.  We are now renting a nice house in town.

Moving to town has been difficult, we have had to sell our animals and alpacas and they are sorely missed.  Our daughters were born in our old house and I developed Immali corn and a few other varieties of vegetables there.  It has a lot of memories and moving was far more difficult than I thought it would be.
In our last few days someone stole our firewood and someone else broke into the mud brick house and cut/took the antenna cables (yet didnt steal anything).  We know who did both of these things but unfortunately can do little about it.  That made moving even harder and more emotional.  I have been praying that I can forgive them, yet I find this very difficult.

Babingtons leek flowering after the move

We have also been very lucky, we asked our new landlord if we could keep two guinea pigs and he allowed us to keep them.  This has made the transition far easier for the kids and they often sit outside holding and patting the guinea pigs.  I think guinea pigs are amazing little animals and very under-appreciated pets.  I should write a post on guinea pigs at some point.

We also asked if we could keep some chickens and the landlord graciously agreed.  I truly appreciate being allowed to keep them.  This has been great as we still have eggs.  It has been many years since we have had to buy eggs and I dread the thought of that ever having to buy them again.  I dont have a rooster so will not be hatching any eggs in the immediate future.

Araucana cross and silkie cross chickens

We took our last two sheep to the butcher and they are now in the freezer so we will not have to buy meat for some time.  I doubt we will be growing our own meat here in any way.  Perhaps I will get some quail or be able to set up a small aquaponics system and raise some edible fish when we move next.

This rental house is very nice and the street is pleasantly quiet, but it does not have a vegetable garden.  I dont understand how people grow food without a vegetable garden.  I am at a loss here.  I guess they pay someone else to grow all their food and simply buy it from a supermarket?  That seems odd to me.  There are so many things that I like to eat which I can not get from a store, other vegetables are so much better fresh.  What I would give for even a tiny plot.  They are a bit precious about grass here so I can only grow things in pots which I have to keep on concrete or pavers in fear of damaging the lawn.

Vegetables but no land in which to plant them

The same vegetables from the other end

Duck potatoes, they grow well in a bucket

I dug up some of most types of vegetables/herbs and brought them here with us.  I could not take many of each, just enough to start again.  Some things do well in containers, others do not.  Many plants have died in the move and many more are looking weak.  I hope that we get to move somewhere with a vegetable garden before many more things start to die.

Micro Tomatoes - unfortunately not all survived the move

Chilli seedlings from rare imported seeds

When I get set up somewhere with a vegetable garden I plan to grow and sell vegetables and seeds again.  I miss having a garden.  I may have some Babingtons Leeks and perhaps some other things things for sale soon but cant get too serious or have too many spare plants when growing in pots.  When I do start to sell vegetables again I will list them on my For Sale page.

Yacon Pineapple slaw

I love yacon, it is sweet and crunchy.  I mostly eat yacon raw, I just peel it, slice it thinly and eat it.  We have tried eating it a few other ways and most were good.  It tends to take on the taste of whatever it is in with so is reasonably versatile.  I have even used some of our yacon roots and water kefir grains to make yacon water kefir which was nice enough even though I prefer regular water kefir.

I normally leave the yacon in the soil until I want to eat it, if I happen to leave it for too long the plant simply gets larger and stronger and returns a larger crop next time.  Recently we have moved from our property into a rented house in town, as such I dug up a small number of yacon plants to grow as well as a heap of the tubers to eat.  Being so hot and dry out here the tubers do not last overly long.  I wanted to find a few new ways to eat yacon as I can not stand the thought of wasting it.  I looked on the internet and stumbled across yacon pineapple slaw.

Yacon growing in a pot - it belongs in the soil

I found a nice sounding recipe, then changed it a fair bit, and made it with a group of school children.  It was delicious and super easy to make.  I am putting the modified recipe here partly to share it and partly so that I have it saved somewhere so I can make it again.

Ingredients:
Yacon tubers, 1 large tuber or a few small ones
1 can of pineapple (or a real pineapple peeled and cut into small pieces)
The juice of 1 lime or a lemon (lemons are the poor cousin of the lime, but they are cheaper)
1 chilli (this can be left out)

Method:
1) Juice the lime (or its poor cousin the lemon)
2) Peel the yacon tuber
3) Grate the peeled yacon
4) Add lime juice to the grated yacon.  Mix together.  You have to do this as soon as possible otherwise the yacon will turn black
5) Cut pineapple into tiny pieces, add pineapple and any juice to the yacon
6) Remove the seeds from the chilli.  Cut up the chilli into tiny pieces
7) Mix it all together and serve

It really doesnt get any easier than this, and it tastes great.  It would be easy enough to add other things to this too as long as they are cut up tiny.  I think something crunchy and relatively tasteless such as shredded cabbage would bulk this out nicely.

Some of the more tropical and fruity tasting chillies could also work well in this as they would add taste but would still be crunchy.  There are a heap of tropical tasting chilli varieties, some have no heat while others are super hot, but few are available unless you import the seeds and grow them yourself.  One great place I have found for chilli seeds is pepper lover, they seem to love what they do and tend to include extra seed packets with orders.  Only some species can be posted to Australia so please do check the AQIS BICON database first.
