Tp-889703-1: Environmental effect on expression

--Peter A. Peterson

Tp-889703-1 has an ear type that is similar to Tp1. It arose as a single event in a genetics nursery. It is a dominant mutant. In the greenhouse, either in pots or in a ground bed, it does not have an unusual growth habit, yet is distinguishable from normal non-mutant plants because of thin leaves and a distinguishable tassel. In the field, however, these mutants have a distinguishable corn-grass appearance with heavy tillering (in some cases, upwards of 15). Though it appeared in an En plot, no system has been assigned to it yet.
