Soybean cultivar 6434385

A method of introducing a desired trait into soybean cultivar 6434385 wherein the method comprises:

• a. crossing a 6434385 plant, wherein a representative sample of seed was deposited under ATCC Accession No. PTA-8701, with a plant of another soybean cultivar that comprises a desired trait to produce progeny plants wherein the desired trait is selected from the group consisting of male sterility, herbicide resistance, insect resistance, 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 to produce selected progeny plants;
• c. crossing the selected progeny plants with the 6434385 plants to produce backcross progeny plants;
• d. selecting for backcross progeny plants that have the desired trait and all of the physiological and morphological characteristics of soybean cultivar 6434385 listed in Table 1;
• and
• e. repeating steps (c) and (d) three or more times in succession to produce selected fourth or higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of soybean cultivar 6434385 listed in Table 1.
