In general,
Advantages: (1) can transfer useful genes from non-plant species into plant species. (2) In some cases, transgenic breeding is faster than convetionaplant breeding. (3) Transgenesis approach is an useful tool for plant researches. etc...
Disadvantages: (1) without proper control, transgene can escape into environment, ex. to wild relatives, through 'gene flow', or non-intented targets, ex. non-GMO crops in the fields, (2) Not every plant species has an efficient transformation system or selection agents
Of course, there are advantages and disadvantages other than those listed above.
What're the advantages and disadvantages to use improved varieties of tomatoes, apples, maize, tomatoes regarding their wild types? The evilness isn't in the technology but in the way that it's used. This questions will have different interpretations and answer if you ask to people living in the developing or developed countries.
Major scientific advantage from transgenic plants, is to test the effect of improving a particular trait, e.g. disease resistance or abiotic stress tolerance, and gain knowledge of there are side effects- like reduction in nutrition. This knowledge can be used to improve plants in other ways, e.g. marker-assisted breeding, having a calculated predictable target. In many cases there are no other ways to develop the trait than by transgenic plants- and scientists can work towards that way in advance.
Thanks to everyone for the answers you gave me.
They certainly were useful to me

The main advantages of transgenic plants include larger yield, resistance to diseases and pests and capable of growing under stressful conditions, while their main disadvantages include allergic reactions, emergence of super-pests and loss of biodiversity. Please take a look at the following RG links and PDF attachments for more details.

Thanks!
Transgenesis in plants is a fantastic tool for basic research. From the practical point of view it enables to create in the shortest time new cultivars resistant to pest, diseases, drought, and salinity. It enables also to produce some rare chemicals (therapy).
The disadvantages is the risk in certain cases of spreading the transgenes to wild plants in nature. The seeds are protected by patents and the farmers have to sign contracts to get these seeds (with some limitations such as using part of the harvest to make seeds for the next year). Sometimes the agronomic qualities of the transgenic plants are not as good as the other classical cultivars.In the case of transgenic plants resistant to herbicides, appearance of resistant weeds that need to be eradicated with the classical armful herbicides.
