1. Herbicide Resistance
Herbicide resistance is permanent in weeds and their progeny with dominant 'target site' resistance. In a plant, resistance may be naturally occurring or induced by such techniques as genetic engineering or selection of variants produced by tissue culture or mutagenesis.
2. Insect Resistance
Insect resistance refers to crops that either naturally or through genetic engineering are able to resist insect damage . insect resistance crops generally produce compounds that are toxic to insects that attempt to eat the resistant plants.
3. Virus Resistance
Virus Resistance is the most effective approach to control viruses relies on the use of resistant varieties of crop plants developed by plant breeding methods. Host-resistance genes have been extensively exploited by traditional breeding techniques for the development of virus-resistant plants.
4. Delayed Fruit Ripening
Ripening is a normal phase in the maturation process of fruits and vegetables. Upon its onset, it only takes about a few days before the fruit or vegetable is considered inedible. This process brings significant losses to both farmers and consumer alike. This describes trait allows more time to pass between removal from the vine to the market and thus , increases the shelf life of a fruit. Scientists have been working to delay fruit ripening so that farmers can harvest fruits later to better optimize their flavor. This technology can also reduce a of fruits during transportation, storage and after purchase because they will ripen more slowly and be less susceptible to damage. Climacteric fruits, such as apples, bananas, apricots, melons and tomatoes, are most suitable to the delayed ripening trait.
5. Pollen Control
Genetically engineered genes may move into wild relatives of crops plants when pollen from the genetically engineered crop lands on the flowers of a wild relative. Genes that are foreign to native plant species may be introduced through the pollen. Such gene spread could negatively impact biodiversity in some instances. No such cases have been documented to date.
