What adject should be used in this context?

'GM technology could create(OR produce) ADJECTIVE crops.
For example, we would see foods with pest resistance and drought tolerance.'

In the above example, I'd like to know what adjective should be used to fill the ADJECTIVE.

I guess 'useful' or 'convenient' could be used in the context,
but am not sure if they are OK.

Also is there any other adjective to express the situation?

Genetically Modified foods are on the market already. There are pros and cons of having genetically modified food. If you want to say something positive about it, you can say:

GM technology creates superior quality crops, nutritionally advanced, taste inhanced , insecticide-resistant. Overall an excellent choice.

Or just 'improved'.
