1. A method of creating a population of soybean plants with a low iron growth condition tolerant phenotype, said method comprising:
- a. genotyping a first population of soybean plants or seeds;
b. detecting in said first population of soybean plants or seeds, a polymorphic nucleic acid marker linked by less than or equal to 10 cM to an allele of SEQ ID NO;
70, wherein said allele of SEQ ID NO;
70 is associated with a low iron growth condition tolerant phenotype;
c. selecting based upon said genotyping a soybean plant or seed containing said allele that was detected by genotyping;
d. crossing or selfing said selected soybean plant or a plant produced from said selected seed; and
e. producing from said crossing or selfing a population of progeny plants comprising said allele of SEQ ID NO;
70 that is associated with the low iron growth condition tolerant phenotype;
wherein said allele of SEQ ID NO;
70 comprises an Adenosine at position 201.

Abstract
The present invention provides methods and compositions for identifying soybean plants that are tolerant or have improved tolerance, or those that are susceptible to, iron deficient growth conditions. The methods use molecular markers to identify, select, and/or introgress genetic loci modulating phenotypic expression of an iron deficiency tolerance trait in soybean plant breeding. Methods are provided for screening germplasm entries for the performance and expression of this trait.
