Synopsis Varieties and selections with long coleoptiles emerged more rapidly than those characterized by shorter coleoptiles. Emergence rate indexes were found to parallel coleoptile length. Standard‐height varieties produced longer coleoptiles than the semidwarfs for all depths at 50° F., while at 90° semidwarf selection 14 × 53‐101 rated second at the 2‐inch and 4‐inch depths of planting. At the 3‐ and 4‐inch planting depths emergence was reduced between 15 and 49% at 50° and 48 to 81% at 90° when compared to emergence percent at the 2‐inch depth.
