There was talk last spring that the 2 numbers were the same corn. I talked to an FS agronomist this week and he told me they are not.
He said they tested the 6499 for FS but didn't advance it due to green snap the year they tested it. I don't know when that was but 63SX1 has been around for at least 4 or 5 years.
He also told me 6499 and Wyffels 7888 are the same corn.
FS 63SX1 vs Agri Gold 6499
