Doctoral Program

Ph.D. in Plant Breeding Genetics and Genomics

A Ph.D. in Plant Breeding, Genetics and Genomics (PBGG) is research-based and prepares students for industry jobs and faculty or research associate positions in academia.

Application and admission is through the Graduate School upon review of applications by the PBGG Graduate Committee and acceptance into the research program of one of our Graduate Faculty.

Transcripts, letters of reference, statement of purpose and standardized test scores are all taken into account during evaluation. While a GRE score of 286 is considered the minimum, 309 is the average GRE for PhD students admitted in the last several years (submission of GRE is optional). Foreign applicants may be required to submit TOEFL (Test Of English as a Foreign Language) scores with a minimum score of 80.


Program of Study

Students may enter the PBGG Ph.D. program with or without a Master’s degree, although degree program requirements are different (see below). An additional track to admission is through the Integrated Plant Sciences portal.  Dissertation research is conducted under the supervision of a major advisor and according to a research proposal approved by a five-member advisory committee. Ph.D. students are required to pass written and oral comprehensive exams prior to admission to candidacy for the Doctoral degree.
