Description:
Four popcorn hybrids, A3004, 33122, P203, and 62180 were intermated in a diallel fashion. A3004 is a private hybrid from Ames Seed Farms, P203 is a released hybrid from Purdue, and 33122 and 62180 are non-released Purdue experimentals. A3004 and 33122 were chosen for their large popping expansion, 62180 for its excellent stalk strength, and P203 because its pedigree includes inbred lines found in the other hybrids.
