| 520 | _aStudies of the genetic structure of the Iowa Stiff Stalk Synthetic (BSSS) and Iowa Corn Borer Synthetic No.1 (BSCB1) maize populations are significant because these are the heterotic groups that form the basis of the modern hybrid maize industry (Senior et al. 1998). Previous work in these populations (Labate et al. 1997, 1999) has demonstrated that examining changes in allele frequencies is an ideal approach to exploring genome-wide changes resulting from reciprocal recurrent selection. Reciprocal recurrent selection is a cyclical process of developing a population, evaluating individuals, and selecting desirable individuals as parents to begin the next cycle of selection. This method of inter-population improvement proposed by Comstock et al. (1949) has been used to improve the BSSS and BSCB1 populations. The objective of this method was to improve the performance of the population cross by increasing the frequency of favorable alleles within the populations, without losing genetic variability. | ||
