Seed parents for 100 degree heat

Looking for seed parents which won’t abort under daily 90-100 degree heat.

Sadly there is only a short spring window where most of my roses actually set hips, and it’s during thunderstorm season so I lost a lot of those to crazy rain and hail, leaving me to discover that only one of my seed parents semi-reliably set hips in the hot, humid summer. And even then I still had lots of aborts and those that survived didn’t produce many seeds.

At this point I really don’t even care about the attributes of the rose, I’ll take any rose that can be used as a broodmare under high heat and rain.
