Also don’t some companies account for longer and shorter dry down characteristics when calling a hybrid let’s say a 100 day and 102 day. The 102 might reach black layer at the same GDU's as the 100 day, but it takes longer to dry down to a harvestable moisture for grain.
All the different characteristics is where the subjective nature of hybrid maturities comes into play. Heat units and stages don’t lie (mostly lol), but putting a relative maturity label on a hybrid seems more an art than a science. |
Pionner seed GDU rankings?
