How about if the plant seleted can "breed" true
or not by seed.
That is something that happens with hybrids.

The pros should be pretty obvious, I mean what are the breeding the plant for right?
And you don't necessarily have to list many different types of pro/cons. It's important that you explain each and give specific and enough examples to prove your point.

pro - get all the desirable quality- bigger fruit, more resistant to diseases, more productive

con - loss of some indigenous species, limited genetic diversity causing possible extinction
