Hybrids? No, thanks!

Here some of our tomato plants growing in the garden

Last spring we planted some vegetables. It's my wife that mostly takes care of the little plants, but both of us put all our enthusiasm into this enterprise and finally, after much success with zucchini, in this period we are beginning to harvest our beloved tomatoes, maybe a little late, due to our mountain climate. We are very proud.

Our tomatoes taste much better than the ones you can buy at the store, because the fruits ripen while still on the plants. If only a tomato could be put in the telephone cable i would let you taste it yourself.

The prize for our devotion was being able to see the whole growth, from the seeds to the resulting fruits. But it's not only for this that i like the idea of gardening vegetables. I believe that producing our own vegetables shows that, atleast in part, one can exit from the logic of consumerism that fattens our society despite the poor countries.

Self-production of vegetables, moreover, reduces to the minimum any waste, especially in a subsistence system upon which the plants grow from the seeds saved from the previous year's harvest (we are planning to try this method). This past year experience delighted us so much that we have already begun to buy seeds for next year, and in this research i discovered a disconcerting thing.

At the store the tomatoes we like most are the "Mini San-Marzano". So we tried to look for informations about seeds of this variety, and we discovered that they are hybrids. In flower shops and nurseries we noticed also on packaging of other vegetables seeds the lablel "F1 hybrid" well shown.

As an ignorant that i am, i tried to give a meaning to this expression, as an analogy to the animal world. An hybrid is an individual born crossing parents of two different races. But what about it in botany?

Tomatoes "Rouge d'Iraq" variety

Surfing the Internet it opened to me a new world. A hybrid (i was looking in particular for tomatoes, but it applies also for a big number of other vegetables that are at the base of entire continents alimentation, like corn) is a plant born from a seed obtained from a fruit produced with a particular technique of artificial impollination.

The first step lies in reproducing plants by mean of autotrophic breeding, for a number of six to ten generations. Since tomatoes are hermaphrodites (that is that every flower contains both the masculine and femimine element), it is possible that they self-fecundate (autotrophic pollination).

This type of breeding obtains children-plants weaker than their parents, because (if i well understood) also the recessive genes reply. In genetics, between two alternatives, the dominante (stronger) gene tends to win, and this gene usually brings the best peculiarities, for example the vigor of the plant (infact a gene that carry a looser peculiarity would be already extinct in the history for natural selection). In an autotrophic pollination, instead, the genetic patrimony of the style (feminine part) is identical to the one of the pollen (masculine part), and so also the recessive genes can reply undisturbed.

Once obtained plants like that, weak but pure, the second step is to cross, by mean of artificial pollination, the styles of one genetical line with the pollen of another one (the artificial pollination is mandatory to be sure that the flower don't self-pollinate again). This process produces plants much more vigorous and fructiferous than the ancestors that started the lines. The seeds produced from the fruits of these plants are labeled as "F1 (= first generation) hybrids". So, buying seeds of "hybrid F1" varieties one can expect a better production, and this, if it is already stimulating for a little garden of one's family, it is fundamental for productive farmhouses.

Tomatoes "Cherokee purple" variety

The problem of hybrids obtained like that is that those plants produce fruits that contain seeds which genetic patrimony is very poor, so the next generations tend to be always weaker and weaker. So much that it proves inconvenient to use the seeds of the previous harvest to grow the next year plants.

The consequence of this is that the farmers must buy every year the seeds for their plantations. And who gets the benefits are the companies that produce hybrid seeds. Their strategy is to find commercially valid varieties, push them on the market and create a demand, so that the farmers must convert to those varieties and buy the seeds year by year.

Few multinational companies, which names are already known for production of genetically modified organisms (Monsanto, Pioneer,...) control also the market of these seeds, and so they are progressively becoming owner of the entire agricultural and food market, manipulating economy of poor countries that lived with subsistency farming till now.

For the farmers themselves it's impossible to learn to produce their own seeds by mean of ibridation, because, above the special skill required, this technique also needs a big effort in labor. Easier, for them, to buy the seeds from those multinational companies that brilliantly solve this detail of overworking cheap labor of the poor countries.

I am kind of ignorant about this matter, and till few days ago i didn't even know the existence of hybrid seeds. I wonder if there exist a movement that opposes to these techniques similar to what it is happening for GM products. I wonder if there is a regulation in Italy (i doubt there is any in the USA, being that there is none for GMO either) that imposes atleast to label the seeds obtained in this way.

I wonder, at last, how could it be possible to make an ethical shopping when buying vegetables in the stores: for what i know not even organic agriculture refuses hybrids.

Our tomatoes in these pictures are - i hope - all non-hybrids.

Good morning!

A new working day is gonna start. Still not completely awake, i go to open the door to the terrace/garden and i let the dogs out for any kind of answer to the call of Nature, and i put the coffeepot on. I go back to the bathroom and i finally get awake with some cold water on my face. When i go back in the kitchen the coffee is ready.

Today's breakfast

Some of my blogger friends know that i am under a diet, but the breakfast, it's known, is the most important meal of the day, so, there i am to set a healty plate to start the day in the best way.

Here it is my breakfast for today: one peach, a kiwi, some corn flakes, some yogurt, a cup of coffee (i like it black with no sugar) and a couple of toasted bread. Sometimes i add also a glass of fruit juice, a few of milk, a slice of cake or a couple of cookies.
Obviously the type of fruit depends upon the availability of the fridge and the season: cantaloup, plums, apricots are common variations. It will be more difficult to find some alternative during the winter.

Considering that since few times ago i couldn't swallow anything else than the cup of coffee, this is a big qualitative leap, isn't it?

What do you like to eat for breakfast?
