W Texas | Well, you may have trouble. I don't know how to predict it based on the frost on the inside of the stem. What happened was there was moist air in the stem and the temperature got below dew point, causing dew and frost on the inside, I am sure.
You need to wait several days and recheck the heads inside the stem. If they are ruined, the heads will turn white and limp and if they are still good, they will stay green. This is how it works with wheat, and I don't see why rye would be any different.
Here is a great review for assessing wheat frost damage:

If the head is ruined, be ready to swath and bale it or chop it for silage, or turn calves on it. Rye will keep growing into June in SW Oklahoma if it is heavily grazed and has moisture. Still not a total loss is you can utilize it as forage! | |
