The purpose of this study was to evaluate the use of a Design II mating system (incomplete diallel) as a means of obtaining unbiased estimates of genetic variances in open-pollinated populations of corn. The Design II scheme was employed in order to eliminate possible bias resulting from assortative mating with respect to date of flowering which may occur when using the Design I mating system with an open-pollinating variety. When compared with previous results from the variety Hays Golden the results obtained in this study are in agreement with the expected changes assuming the Design II eliminates the problem of assortative mating.
