*   Full-season hybrid.
1.  L = loose husks, M = medium-tight husks, and T = tight husks.
2.  Overall resistance to insect injury evaluations were made on the basis of total percent damage to the
     ear by one or more of the following insect categories:  corn earworm and fall armyworm, maize weevil,
     and pink scavenger caterpillar.  Ratings were made on a scale from very good to very poor, where
     VG = very good, G = good, F = fair, P = poor, and VP = very poor.
