Abstract
A winter wheat line of Triticum aestivum L. em. Thell. (aestivum group) segregating for a semidominant gene for dwarf stature from 'Tom Thumb' was crossed with 'Wichita' or 'Cheyenne' aneuploids. The F1 progenies segregated into two height groups in a ratio of 1:1. F2 disomic and noncritical monosomic progenies segregated in a ratio of 1 short: 2 intermediate:1 tall. Monosomic analyses involving all chromosomes except 2A, 4B, and 6B indicated that the dwarfing gene was located on 4A. The heterozygous and hemizygous states of the gene had the same effect on height.
