Gentlemen, thank you both for taking the time to offer advice. I truly
appreciate it.

Timothy, thanks for the URL to the botrytis page. The photo they have of
the rose looks much more diseased than the photos my friend sent me.
(By the way, here's the standard URL to the site:
http://www.sunriveronline.org/misc/roses )

It could very well be a simple case of faded flowers. As I said, I don't
know anything about roses, and when I saw the new rose bud turning brown,
I thought there might be something more sinister involved. But I'll
advise them to keep an eye on them.

I did pass along Doug's excellent advice on the five-leaf pruning method,
so even if it is a simple case of fading flowers, we learned something in
the process.

All the best to you both.

Thanks for the direct link to the photos. The second photo from the top
looks like a good candidate for botrytis in the early stages. Compare for
yourself he

The other most common issue with rose blooms turning brown would be
thrips. Thrips feed on the open buds and cause brown edges on the petals.

Yet another simple explaination could be that they got hosed down and were
transported wet and the blooms that were already set started to rot.

My suggestion would be to remove all distorted/affested buds and flowers.
Wait untill the next flowering and see if the problem continues. If so,
inspect the the flowers and buds very well ,ripping the flowers apart to
see if thrips are living in there. If no thrips are present, then strat
thinking about botrytis. Good luck.
