John W. Dudley

Research Responsibilities

My research program is aimed at improving plant breeding methods by developing and testing quantitative genetic theory related to breeding methods. A major part of the program is devoted to determining the best way to use molecular marker technology to improve breeding programs and to understand genetic control of kernel composition. Because of its importance in Illinois and its advantages as a genetic organism, all my research is done using maize. An important part of the program is the study of limits to selection, particularly for oil and protein concentration in the kernel. This work continues the work started by Hopkins in 1896. Major efforts to improve efficiency of incorporation of exotic germplasm into adapted inbreds also are underway.

Teaching Responsibilities
