The more you know the less you know

On 5-19-03 I pollinated 2 flowers on one of my earliest blooming hybrid rugosas with R. glauca pollen. Today, 6-16-03 one of the hips is big and fat and the other is shriveled, almost black and ready to fall off???

If there is any doubt that I may have gotten to the bud too late and it may have self-pollinated, I put a question mark on the zip lock bag. Neither bag had a question mark.
