some of the rose bushes have reverted back to the small wild red rose, not the entire bush, but at least half.

Sounds like the rootstock is trying to take over. Roses, like many other plants, including fruit trees, are often grafted. That is, the upper part (in your case, the hybrid tea) is grafted onto another rootstock, often a wild relative that is particularly hardy or disease resistant. So what you are seeing are sprouts coming from that rootstock and overtaking the less vigorous hybrid tea. On grafted plants it is important to prune off any of these root suckers to prevent this problem. I'd prune away anything that is not the original rose and anything coming from below the graft (swelling on the stem). If you allow the vigorous suckers to grow, they will completely overtake your hybrid tea.
