Rolla, ND | Well it's mostly a matter of breeding harvest dormancy into the varieties. There is a lot of dormancy bred into the spring wheat and so they are very resistant to sprouting in the swath and I've never seen sprouting standing though the falling numbers can go down. Varieties vary some but they all have a lot of dormancy compared to the winter wheats.
Winter wheat is intentionally bred to sprout. That's because people harvest and just a few weeks later they plant that seed. We really try hard not to swath winter wheat. Just a little rain and it sprouts.
"Solution" would be to breed in dormancy and use seed from last year. For obvious reasons there is quite a bit of resistance to that idea.
In durum, it's pretty common to do a germination test in the fall and get something like 40% and after it spends the winter in a bin, it grows just fine in the spring.
