at the right time. the floodgates had opened a church cannot be added in another to see the hall one victory for by and a scoreline that might sound familiar as by and eventually or for one lost against hoffenheim earlier in the season. you're watching do the news coming up next flying cars might be closer than you think stay with us. and you hear me now oh yes we don't need you and how last year's german chancellor will bring you back or if you've never cards have surprised yourself with what is possible who is magical really what moves her and want also to talk to people and follow along the way maurice and critics alike join us for metals lifestyle.

oh. it is often said that fruits and vegetables used to taste much better and that they were healthier but with a reading. the echoed immediately kowtow to falls in paris is the sounds of knowledge regarding old plant for i a ts. between the old agronomy publications we find something special. in nutritional composition table food fruits and vegetables it is 16 years old. it lists the vision and mineral content of each and every variety. and indeed over the last 60 years many fruits and vegetables seem to have lost some of their nutritional value. how did.

they discover american biochemist donald davis next is on the subject. i'm here to tell you about an important problem that many people are not aware of nutritional declines in foods. davis works at the university of alston texas and has analyzed the development of 43 vegetable varieties between 950 and 999. i think that most of these declines are caused by increases in yield when you go up there's less nutrients per weight of the food a lot of agricultural scientists may not know about how big these effects are this

is kind of an embarrassing of their they're always wanting to increase you if modern breeding was causing increases in flavor and increases in nutrients i think they would talk about it a lot more. but to most of it is one of the fruits that has lost a lot of nutrients looking back it is clear that this has to do with the royalties as well as the sea. down is all over the world she's been seeds from brushes like this. to supply it's all agricultural groups such as syngenta b.s.f. and down. the self documenting up based on size shape color and a high heeled. abbreviation f one if one is important. it means 1st generation hybrid.

the breeding of hybrids works respondants. take the plants of the variety that for example has lunch but too pale to. process with another variety of his fruits of beautifully red but much too small. from this cross-pollination the hybrid is creating a plant that contains genes from both the large pale tomato and the small red one. from as early as the 1920 scientists around the world have been using this technology. a main goal to produce and indestructible tomatoes. we know that crash test for cars but for to tell us. that. only with the help of genetic engineering was this possible. in

994 the flavor saver to moscow was launched in the usa. one of the problems was that older 2 massive varieties spoil quickly. began looking for the eternal tomato. best selves let them to israel. feel more than 70 years families here have managed to grow fruit and vegetables in the middle of the day. you need you to do you eat at the hebrew university of jerusalem you will meet one of the creators of the almost immortal to military. of each. the 79 year old professor

emeritus continues to develop a perfect type of plants this is a breeding greenhouse so it's plant is different and i say what's responded look stronger than this one for instance definitely more than this one we look for these differences in order to develop something which is better than the existing material. for the research and his team work at the university but on behalf of private companies they work is currently funded by the french see it produce it. it's owned by them i cannot i cannot give it to anybody else this is exclusive to the consumer to them you are the only one to get into these greenhouse beside you no one can get from. one of the 2 men are creating a tomato for southern europe used to be one of the more i know looking to have

a winning eye but it's in the bulk of the market which has a solid size a rounds freons with ground. it's a muscle as big as a grapefruit and it should grow horizontally last hour which is the flow organize. usually is a class that has some dimensions of fruit growing every possible direction up people like today want to call a fishbone kloster some backing point of view if you have 3 dimensions very difficult to park in a box when you have a 2 dimension you can put one on top of the other and it's much easier. for the design type rate to single variety plants across the flower of one is pollinated with the pollen of the other is the way the stuff. you need to come off and. this is what they call off the fish and. it's really you know what it is.

just move the process put the. composer. said to put you can see and all you know dust. and in 2 days a week on we did all that and i would make it for the nation. how many crossing you make to have a one i really i begin. to make a commission i believe will be $400.00. $400.00 like that for i need every year. sometimes coming on the phone to 30 or so we can go through a good snow. this is house kind of benefits and his teaching off to thousands of cross-pollination is created be eternal to me in the night 970 s. their invention revolutionized the world market. where you begin to work on the long sail in life because because of this waste of 40 percent of the who the used

before this mutation the limit was to 3 days full days at the most when we export at the mud goes to europe and we exported the lot the most to whoop we used to flight by openings because if it has to go by boat form is rigged to most saves the mother would be motion nobody nobody would touch it. to extend the shelf life the scientist uses a mutation he discovered by chance the purpose of this tomato is to disseminate his seed for the next generation so the moment of the seeds are ripe. to fall off the bush bump into the ground. explode and all these jews when will run all over as far away from the mother plant as possible in order to. go for multiple tori we don't want to it's undesired straight for human beings.

the solution. for the new hybrids the israeli research is crossed plans of a classic to mars have a right to peace process runs after 3 days with mutated plants whose genes prevent the fruit from ripening. the result hybrid that decomposes much more slowly after harvesting. we're going to do a simple experiment on the right a perfect flawlessly beautiful hybrid fruit. and on the left a traditional form is to matter. it is anything but perfect with yellow spotted skin and small float. now we just have to wait. after 3 days both to mars has

a still fun and presentable. after one week the farmers to monitor is unsellable the black spots indicates a deterioration. and the hybrid unchanged even after 2 weeks the stem has come loose but that's not a fun. only after $25.00 days is the hybrid tomato deemed not fit to be sold as it developed moved you spots and loose skin. the normal tomato no looks like this. on the supermarket shelf only the hybrid is able to be displayed for 3 weeks. but eternal youth 1st its price. you can this event.

tastings the genes for any bishan ripening to be sure. curry were very. negative traits. for instance flavor that they just deteriorates and they are left no trace but i don't know because we know there's never been as it only late in the ninety's and early 2000 we started looking into the quality traits i offered a project like that too many said companies even gave it a name i called it a. case of a thing in ac and they said it would be much healthier to model we don't have it now suppose market is the industries that don't care. the industry the seed produces. the israeli company has vera is one of the heavyweights in the

seed market is there and millions with the eternal to march. in 2003 to 0 was posed out by the multinational limit congress with an annual turnover of several 1000000000 years. following the acquisition of his era limo girl became one of the largest seed produces in the world. in the middle of the negev desert the company is experimenting with new hybrid variety. your own she rests is the product manager responsible for the worldwide marketing of tomato seeds you know resin felt is the press office and this is for you and then you go to. our protocol for some information.

in. all 120 has 0 varieties are grown in this greenhouse. we're going to show you for example the tomatoes if we call it lamb your face is very famous say tomato in 2 key today it's a green part of lead to weight loss it's like a mustache you know there is a special sheen forest misstates yes yes so you see very very nice a color very from tomato is coming from the long shelf life family also and you mean that it has a long genes inside like this a percentage of all your very t. but. i didn't calculate what i assume today around 5050. slice has a long shelf life in there for for a long time we saw that it was influence to reduce the taste of the tomato and now

we are going back and try to increase the test again of the tomato. yeah russ wants to prove to us that durable tomatoes can also be delicious. days. ok likely. we said that it was said that not all the tomato need to have a taste because if you only boil and salt you don't need they just. for food and i thank you i know what is the method to make this is ok yeah ok yeah. there is a worse. but holding out that info what they want this is ok what we're looking more and more is it to have a good color and a good firmness and a good taste.
