A method of introducing a desired trait into soybean cultivar S100319, wherein the method comprises:

• (a) crossing a S100319 plant, wherein a representative sample of seed is deposited under ATCC Accession No. PTA-12194, with a plant of another soybean cultivar that comprises a desired trait, wherein said desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance, abiotic stress tolerance, modified fatty acid metabolism, modified carbohydrate metabolism, modified seed yield, modified oil percent, modified protein percent, modified lodging resistance, modified shattering, modified iron-deficiency chlorosis and resistance to bacterial disease, fungal disease or viral disease;
• (b) selecting one or more progeny plants that have the desired trait;
• (c) backcrossing the selected progeny plants with soybean cultivar S100319;
• (d) selecting for backcross progeny plants that have the desired trait;
• and
• (e) repeating steps (c) and (d) two or more times in succession to produce selected third or higher backcross progeny plants that comprise the desired trait.
