Abstract
Computer simulations are useful tools to optimize marker-assisted
breeding programs. The objective of our study was to investigate the
closeness of computer simulations of the recurrent parent genome
recovery with experimental data obtained in two marker-assisted
backcrossing programs in rice (Orzya sativa L.). We simulated the
breeding programs as they were practically carried out. In the
simulations we estimated the frequency distributions of the recurrent
parent genome proportion in the backcross populations. The simulated
distributions were in good agreement with those obtained practically.
The simulation results were also observed to be robust with respect to
the choice of the mapping function and the accuracy of the linkage map.
We conclude that computer simulations are a useful tool for
pre-experiment estimation of selection response in marker-assisted
backcrossing.
