Pioneer does not start counting GDUs until emergence while Bayer starts counting at planting date. A 104 day Pioneer will act like a 107 or 108 day Bayer number.
I was 99% you were wrong, but i confirmed it anyway. Pioneer DOES NOT start counting gdu’s until emergence, they start on planting date. While there is no standard in the industry for stating a hybrid’s maturity since each company rates it based on more than just gdu’s to black layer, hence some may seem earlier than another or later than another, but when using gdu’s to any given stage they should all be similar or certainly within a little bit of each other assuming the company didn’t make a mistake. As always weather does affect some hybrids differently from year to year which could explain some differences seen from year to year.
Pionner seed GDU rankings?
