An heirloom tomato ( besides called heritage tomato in the UK ) is an open-pollinated, non-hybrid heirloom cultivar of tomato. They are classified as : syndicate heirlooms, commercial heirlooms, mystery heirlooms, or created heirlooms. They normally have a shorter ledge life and are less disease repellent than hybrids. They are grown for a assortment of reasons : for food, diachronic interest, access to wider varieties, and by people who wish to save seeds from year to year, vitamin a well as for their taste. [ 1 ]
taste [edit ]
many heirloom tomatoes are sweet and lack a genic mutation that gives tomatoes a consistent loss color at the monetary value of the fruit ‘s preference. [ 2 ] Varieties bearing this mutation, which have been favored by industry since the 1940s, sport fruits with lower levels of carotenoids and a decrease ability to make sugar within the fruit. [ 3 ]

Heirloom tomato cultivars can be found in a wide variety of colors, shapes, flavors and sizes. Some heirloom cultivars can be prone to cracking or lack disease resistance. As with most garden plants, cultivars can be acclimated over several gardening seasons to thrive in a geographic localization through careful choice and seed saving.

Seed collecting [edit ]
Heirloom seeds “ breed true, ” unlike the seeds of crossbreed plants. Both sides of the DNA in an heirloom diverseness come from a common stable cultivar. Heirloom tomato varieties are open pollinate, so cross-pollination can occur. Generally, tomatoes most likely to cross are those with potato leaves, double flowers ( found on beefsteak types ), or currant tomatoes. All of these should be kept at least 50 feet apart. All other tomatoes should be kept at least 20 feet apart to reduce the possibility of cross-pollination. Seed should be saved from tomatoes picked from several different plants over the path of the growing season that are dependable to type to preserve genetic diverseness. These seeds should be mixed at the end of the growing season. [ 4 ] There are two chief ways to save heirloom tomato seeds. The first method is to let the tomato ripen completely, even to the point of beginning to rot, and then remove the seeds with a spoon and spread them on a piece of fabric or paper to dry. Some people spread them out on a paper towel, let them dry, and then plant the paper towel and seeds together in potting or germinating territory. The irregular method acting to save tomato seeds uses the agitation work. The tomatoes are allowed to overripen then cut to expose the seed cavities. The seeds are then scooped out and put into a container. The tomatoes need to be stirred one or more times per day for three or more days until the seed mix is bathetic. As agitation takes place some fungal growth will appear on top of the concoction, but that is convention. At the end of the zymosis action the seed concoction is stirred and the seeds dislodge from the mousse and sink to the bed of the container. Water is then poured into the mix, the pulp and the regretful seeds will rise to the top and flow over the side of the container, while the good seeds sink to the bottom. Once the water becomes clear strain the remaining seeds then spread the seeds out to dry. Once the seeds are dry mix the seeds in concert, breaking aside any that are stuck together, and put the seeds in a tightly sealed credit card pocket. Seeds should be dated, labeled, and stored at room temperature, away from mastermind sunlight. Heirloom tomato seeds may be stored for up to ten years. [ 5 ]
