Education

Research Interests

Dr. Luby teaches courses in fruit production and plant breeding. The primary goal of his research is to develop, evaluate, and introduce fruit cultivars with horticultural, disease and pest resistance, and fruit quality characters desired by growers and consumers in Minnesota and surrounding areas. The breeding programs concentrate on apple and grape. Research aims to determine the inheritance of these traits and, where appropriate, map important loci using molecular markers for use in marker assisted breeding. Recent or current examples include traits related to fruit quality and scab resistance in apple, resistance to apple scab, and low temperature responses, disease resistance, sex type and fruit quality in grape derived from wild Vitis riparia.
