Patrick Rubaihayo (4 April 194014 May 2024) was a Ugandan academic, plant breeder, biotechnologist, and politician. He served as Professor Emeritus at Makerere University, where he taught and conducted research for over five decades in the fields of plant breeding, tissue culture, and agricultural biotechnology. He also served as Member of Parliament for Mbarara Central and as State Minister for Agriculture in the second government of President Milton Obote (1981–1985).

Early life and education Rubaihayo was born on 4 April 1940 in Mbarara District, Uganda. His early education included attendance at Mbarara Junior School, Mitooma Primary School, Kabwohe Primary School, Mbarara High School, Kigezi College Butobere, and Ntare School.

In 2005, he was appointed Professor Emeritus and continued his association with the university until his death. He taught and supervised research in the College of Agricultural and Environmental Sciences, with contributions to plant breeding, banana production systems, tissue and cell culture, molecular biology applications in crops such as bananas, sweet potatoes, and soybeans, and other agricultural research projects.

Scientific contributions Rubaihayo conducted extensive research in plant breeding and agricultural biotechnology. His work included studies on banana production systems, molecular diversity in bananas and sweet potatoes, variability in potato and cowpea viruses, and soybean genotypes. He collaborated on evaluations of advanced-generation soybean lines and supported initiatives in banana breeding and processing. He was also involved in efforts to promote biotechnology applications in Ugandan agriculture.
