Organicheirloom tomatoes atSlow Food NationAnheirloom tomato(also calledheritage tomatoin theUK) is anopen-pollinated(non-hybrid)heirloomcultivaroftomato. Heirloom tomatoes have become increasingly popular and more readily available in recent years. According to tomato experts Craig LeHoullier and Carolyn Male, heirloom tomatoes can be classified into the four categories of family heirlooms, commercial heirlooms, mystery heirlooms, and created heirlooms. They are grown for a variety of reasons, such as historical interest, access to wider varieties, and by people who wish to save seeds from year to year, as well as for their taste, which is widely perceived to be better than modern tomatoes.[1]They do, however, have a shorter shelf life and are less disease resistance than most commercial tomatoes. Furthermore, some scientists have suggested that heirloom tomatoes are no more natural than commercial ones, and that many are simply "inbred" tomatoes.[2]Contents

[edit]TasteHeirloom tomatoes lack a genetic mutation that gives tomatoes an appealing uniform red color while sacrificing the fruit's sweet taste. Varieties bearing this mutation, which have been favored by industry since the 1940s, feature fruits with lower levels ofcarotenoidsand a decreased ability to make sugar within the fruit.[3][edit]CultivarsMain article:List of heirloom tomato cultivars

Selection of heirlooms, plus one hybrid, the Early Girl (second largest red)

Heirloom tomato cultivars can be found in a wide variety of colors, shapes, flavors and sizes. Some cultivars can be prone to cracking or lack ofdisease resistance. As with most garden plants, cultivars can be acclimated over several gardening seasons to thrive in a geographical location through carefulselectionandseed saving.

Some of the most famous examples includeSan Marzano,brandywine,Gardener's Delight,Lollypop,Cherokee purple,Mortgage Lifter,Black Krim,Amish Paste,Aunt Ruby's German Green,Big Rainbow,Chocolate Cherry,redcurrant,Three Sisters.

[edit]Seed collectingHeirloom seeds "breed true," unlike the seeds ofhybridizedplants. Both sides of theDNAin an heirloom variety come from a common stable cultivar, in contrast to hybridized seeds, which combine different cultivars. The hybrids exhibit "hybrid vigor" in the first generation, but the second generation tends to exhibit many undesirable recessive traits. Heirloom tomato varieties are "open pollinating", but cross-pollination is very rare without human intervention.

Heirloom seeds can be easily collected and will continue to show the traits of the original seed because this family of tomatoes almost always self-pollinate. Collecting heirloom seed is as easy as picking ripe tomatoes, chopping or mashing into a jar till less than half-full, filling with water, shaking from time to time and allowing to decompose for 1-6 days until seeds sink to the bottom, then rinsing until the seeds are clean, and drying. This decomposition is beneficial because it discourages transmission of diseases to the seed, the drying promotes better germination, and because the seeds are easier to separate when they are clean.

Slow Food Nationwas an event organized bySlow Food USA, which celebratesslowandsustainablefoods. One of the largest food events in U.S. history, Slow Food Nation attracted an estimated audience of more than 50,000 people.[1]

http://www.iseoverde.ro/soiuri-si-hibrizi-la-tomate-tomate-rosii-tehnica-culturii/Cele mai cultivate soiuri de tomate Cei mai utilizai hibrizi de tomate n cultura

Soiurile i hibrizii de tomate sunt n numr foarte mare , an de an aprnd noi soiuri i noi hibrizi , create de cercettori.

Clasificarea soiurilor i hibrizilorde tomate este foarte anevoioas , iar criteriile luate n considerare sunt foarte variate : criterii de ordin ecologic , biologic , morfologic , destinaia produciei i altele.

O clasificare de mare actualitate i importan este aceea care are drept criteriu durata perioadei de la rsrirea plantelor pn la recoltarea primelor fructe , denumit i perioad de vegetaie.n funcie de acest criteriu , soiurile se pot mpri n trei grupe :

- soiuri timpurii , care necesit o perioad de 95 120 zile ;

- soiuri semitimpurii , care necesit o perioad de 120 130 zile ;

- soiuri trzii , care necesit o peroad de peste 130 zile.

n abordarea acestei clasificri nu trebuie neglijate ns condiiile de cultur , care influeneaz perioada de vegetaie.

Dintre caracterele biologice i morfologice care stau la baza clasificrii soiurilor , cea care prezint o importan mai mare este nlimea plantelor.n funcie de acest criteriu , soiurile se pot grupa n trei :

- soiuri cu port nalt , la care tulpina poate ajunge la 180 cm ;

- soiuri cu port seminalt , cu tulpini de 80 100 cm ;

- soiuri cu port pitic , cu tufe de pn la 80 cm.
