Molecular markers associated with soy iron deficiency chlorosis

A method of producing a soybean plant with increased tolerance to iron deficiency chlorosis (IDC), the method comprising the steps of:

• a. isolating at least one nucleic acid from a population of soybean plants;
• b. detecting in said nucleic acid a marker associated with IDC located within 5 cM of a chromosomal interval corresponding to Glycine max Chromosome 10 wherein said chromosomal interval comprises of SEQ ID NO:
• 15 and further, wherein said chromosomal interval comprises a G allele corresponding to position 251 of SEQ ID NO:
• 15;
• c. selecting a first soybean plant from the population of (a) based of the presence of the marker detected in (b);
• d. crossing the first soybean plant of (c) with a second soybean plant not comprising in its genome the marker detected in (b);
• e. collecting seed from the cross of (d);
• and
• f. growing a progeny soybean plant from the seed of (e), wherein said progeny soybean plant comprises in its genome said marker associated with increased IDC tolerance, thereby producing a plant with increased IDC tolerance.
