Yes, if you want a potato leaf hybrid, both parents need to be potato leaf.

No. With a hybrid approach, the ultimate goal is for an exceptional hybrid that you produce over and over.

The crosses are unique crosses between parents

For example, if you have 6 parents, the crosses you can make are --

1 X 2
1 X 3
1 X 4
1 X 5
1 X 6
2 X 3
2 X 4
2 X 5
2 X 6
3 X 4
3 X 5
3 X 6
4 X 5
4 X 6
5 X 6

15 total crosses (not 20)
