Marcus Morton Rhoades (July 23, 1903 - December 30, 1991) was an Americancytogeneticist, his research on maize led to important discoveries for basic genetics and the applied science of plant breeding.

During her graduate studies and her postgraduate appointment as a botany instructor, McClintock was instrumental in assembling a group that studied the new field of cytogenetics in maize.
MarcusRhoades noted that McClintock's 1929 Genetics paper on the characterization of triploid maize chromosomes triggered scientific interest in maizecytogenetics, and attributed to his female colleague 10 of the 17 significant advances in the field that were made by Cornell scientists between 1929 and 1935.
In the summer of 1941 she took a leave of absence from Missouri to visit Columbia University, where her Cornell colleague MarcusRhoades was a professor.
