Igloo tomatoes

One of my first attempts at breeding tomatoes is also one of my best.  This project began when I was in high school where I had limited access to germplasm and limited knowledge of genetics and breeding.  

I was aiming to breed a tasty, highly productive, early ripening tomato that did not need much water.  Igloo tomatoes tick all of these boxes and more.  

Igloo tomatoes produce red and round tomatoes, they are small salad size tomato, but large enough to be sliced onto sandwiches.  They are remarkably uniform in size, each weighing slightly under 50 grams.

Igloo tomatoes weight almost 50g each

Igloo tomato plants are stocky compact things only growing to around 1 foot tall, sometimes reaching under 2 feet tall.  Being smaller plants means the space can be used for other things, it also means they are not draining nutrients from the soil merely to produce length of stem.  They do require staking as the amount of fruit they produce is too much even for stout little trunks to hold without some support.  

Being small plants does not mean they are less productive, incredibly Igloo tomatoes are one of the most productive tomatoes I grow.  

Each truss has around 16 flowers, sometimes a few more or a few less.  Each plant produces several hundred red round fruit over the season, for me when crammed in too close to other tomato plants they usually around 12kg of ripe fruit.  This doesn't sound like a lot, but 12 kg of fruit produced on a plant that is only a foot tall and one foot wide is spectacular.

For me they are always among the first tomatoes to ripen.  Last time I recorded days, it took 147 days from planting the seed until I picked the first ripe fruit.  This is incredibly quick.  They produce the bulk of fruit before other varieties (including most cherry tomatoes) even start to ripen.  

It is probably best described as semi-determinate.  It does produce a lot of fruit early in the season when no other tomatoes are ripe, and it produces fewer fruits towards the end of the season when many larger and later varieties are ripening.  Even though it is producing less towards the later end of the season, igloo tomatoes always keep producing up until a killing frost.  I have never tried to overwinter them, so don't know how long they can live if protected.

The fruit has a little elbow on the stem, making picking ripe fruit easy an fast.  I think they have the uniform ripening gene, which means the fruit are very evenly red.  I am not a huge fan of the uniform ripening gene, and much prefer fruit with green shoulders, but it was prevalent in the germplasm I had access to at the time I was developing this variety.

Igloo tomatoes never crack or split even if watering is erratic.  I have never had any blossom end rot on these even when other varieties planted next to them are besotted in blossom end rot.  Never cracking, and never succumbing to blossom end rot, means there is not a lot of wasted fruit.

Not only are they among the first to ripen in my garden, they are also one of the few varieties that consistently provide large yields.  Some years the conditions are a bit harsh and other varieties don't really crop, igloo tomatoes always produce about 12 kg of ripe fruit for me.  

Igloo tomatoes produce large seeds, meaning that seed saving is simple.  Larger seeds also tend to remain viable for longer than small seeded varieties.  While seed is always best when relatively fresh, I have grown seed from this that was over 20 years old and had been stored dry in a cupboard.  

igloo tomatoes - not all are ripe enough

I find that these taste ok when not quite ripe enough, but taste great if left to ripen fully.  I tend to allow them to ripen on the plant, but they can be picked early and ripened on the bench.  Like every tomato, they taste best if not put in the fridge.  

I have no idea how well this variety copes with humid coastal conditions, all I know is it performs well for me and produces large amounts of food even with a short growing season.

I have donated seeds of Igloo tomato to a few different community seed saving groups (and encouraged them to distribute the seeds among their members) as it does have the potential to feed a lot of people using a small amount of space.  I hoped to get some feedback about how they perform under different conditions in people's backyards.  Unfortunately I have never heard anything from any of them, and don't know if they have even planted the seeds.  I hope that at least some of them shared the seeds among their members.  

While I am biased because I developed this variety, I think it is a great tomato.  It tastes good, looks nice, provides a huge crop on a small plant, never suffers diseases, ripens early, and is simple to save seeds from.
