Interpretive Summary:

Technical Abstract: The characteristics that define the appearance of a living organism are determined by the interaction of the genes of that organism with its environment. Genes are stored chemical information (deoxyribonucleic acid, referred to as DNA) that provide messages to direct the development of an organism. For example, in the case of a soybean plant, these messages allow the plant to resist attack by pathogens, survive under dry conditions, or to produce oil with a high or low level of saturated fatty acids. With available technologies one can now use a simple laboratory assay of DNA to determine the resistance or oil quality of a plant rather than a more time consuming field or greenhouse assay. We have developed a highly informative set of Simple Sequence Repeat (SSR) DNA markers that are identical to those now being used in human forensic medicine. It can be clearly demonstrated that once an association between a plant trait and an SSR marker is established it is no longer necessary to measure the trait, rather, one can use indirect "DNA marker assisted selection" to identify those plants that carry the genetically controlled trait(s) of interest.
