Abstract

The corrected calculation of inbreeding in mass selection was shown in a previous paper; inbreeding in modified ear-to-row selection was calculated in that paper with the uncorrected equation. In the present paper, inbreeding is calculated for the modified ear-to-row selection method using the corrected equation. Establishing a detassel¬ing plot is the second phase of the aforementioned method. Inbreeding values were quite small; inbreeding was about 6% in selection cycle 100. The reason behind widespread use of modified ear-to-row selection may be smaller inbreeding values.
