OK, I'm not going to do full details, but the basics are:
Choose two plants that have the characteristics you are looking for and breed them together using artificial pollination. Do this with a large sample of plants and grow the plants produced. THis could be done for several generations until you think you have found a suitable plant.
In your answer you are going to need to talk about how you would do the pollination and will need to explain how breeding them together should produce offspring with good fruit, basic genetics really.

 Plant without characteristics crossed with a plant possessing the desired characterists
 Pollen dusted on stigma (anthers are removed prior to this to prevent self pollination).
 Flower is bagged to prevent further pollination
 Seeds of F1 obtained and exposed to disease and then interbred
 This is repeated and "good" plants are selected in each generation of inbreeding
 Back cross with parent (commercial plant) to get background genes. In doing so the background genes of the unwanted plant are diluted.

Quickie summary.
