For the past five years, our laboratory has been attempting to establish a system of somatic cell genetics for soybean. Although our results are far from complete, they are sufficiently encouraging to suggest that such a system will be practical and that it should be possible to construct a complete genetic. map within a few years. The rapidity with which this can be done relies in part on the somatic genetics discussed in this report and in part on a molecular genetic analysis which is now underway
