Oct 31, 2016 · The U.S. Department of Agriculture has approved commercial planting of two types of potatoes that are genetically engineered to resist the pathogen that caused the Irish potato famine.

A genetically modified potato is a potato that has had its genes modified, using genetic engineering. Goals of modification include introducing pest resistance, tweaking the amounts of certain chemicals produced by the plant, and to prevent browning or bruising of the tubers. Varieties modified to produce large amounts of starches may be approved for industrial use only, not for food.

The terms \\"hybrid,\\" \\"heirloom,\\" and \\"genetically modified (GMO)\\" get tossed about a lot today and nowhere more so than in the gardenspecifically, the vegetable garden. In plants, the terms refer to how the plants are reproduced: whether by simple seed saving, by cross-pollinating two different species, or by introducing foreign genes. None of these methods are easily labeled good or bad and you won't find much agreement on which is the best, either. Heirlooms are plants that have stood the test of time, hybrids are often more disease-resistant or higher-yielding, and GMOs although still the subject of much study, can be lifesavers. Each has its pros and cons.
Open pollinatedor OPplants are simply varieties that are capable of producing seeds that will produce seedlings just like the parent plant. Hybrid plants, as explained below, do not do this.
While plants can cross-pollinate in nature and hybrids repeatedly selected and grown may eventually stabilize and become open pollinated, most hybrid seeds are relatively new crosses and seed from these hybrids will not produce plants with identical qualities.
For example, each year new hybrid tomato varieties are offered. You may see them labeled as hybrids or F1, first filial generation (first-generation hybrid), or F2, second filial generation. These may eventually stabilize, but for the moment a tomato like the popular 'Early Girl' does not produce seeds that reliably have the features you expect in an 'Early Girl' tomato. Seed from hybridized plants tends to revert to the qualities of the parents, so tomatoes grown from seeds saved from your 'Early Girl' tomatoes might still be tasty, but not so early.
Anyone can select and eventually stabilize their own seed or even hybridize new plants, but plant and seed companies have recently begun patenting their crosses so that only have the right to reproduce the hybrids they've developed.
Hybrids should not be confused with genetically modified organismsor GMOswhich can be any plant, animal, or microorganism which has been genetically altered using molecular genetics techniques such as gene cloning and protein engineering. Plants like corn that has the pesticide Bt engineered into its genetic makeup to make it resistant to certain pests are GMO crops. Bt is a natural pesticide, but it would never naturally find its way into corn seed.
You probably are not too keen on infusing your food with pesticides and the overuse of a pesticide often results in the targeted pest becoming resistant to it. These types of concerns have given GMOs a terrible reputation. However, there are times when GMOs have arguably been quite positive in their impactsuch as the high-yield, disease-resistant dwarf wheat introduced by Norman Ernest Borlaug which helped increase the food supplies in India and Pakistan.
Sep 20, 2018 · Genetically modified foods, or GMOs, inspire strong reactions nowadays, but humans have been tweaking the genetics of our favourite produce for millennia. While GMOs may involve splicing genes from other organisms (such as bacteria) to give plants desired traits – like resistance to pests, selective breeding is a slower process whereby ...
