Elucidation of the extended pedigree of ‘Honeycrisp’ apple and genetic architecture of its susceptibility to soft scald and soggy breakdown postharvest fruit disorders and zonal leaf chlorosis disorder A Dissertation SUBMITTED TO THE FACULTY OF THE UNIVERSITY OF MINNESOTA BY Nicholas Philip Howard IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY James J. Luby & James M. Bradeen June, 2017 © Nicholas Philip Howard 2017 Acknowledgements I would like to acknowledge the many people that helped make this dissertation possible. My advisor Dr. Jim Luby provided outstanding guidance and set me up with a rewarding project. My graduate committee members Dr. Jim Bradeen, Dr. Stan Hokanson, Dr. Cindy Tong, Dr. Matthew Clark, and Dr. Rex Bernardo likewise provided excellent guidance and expertise. My project was partially funded by the USDA NIFA project RosBREED, which provided wonderful opportunities to collaborate and learn from great scientists including Dr. Cameron Peace, Dr. Stijn Vanderzande, Dr. Lichun Cai, and particularly Dr. Eric van de Weg, who was instrumental in my understanding and implementation of SNP array data in pedigree-based QTL analysis. Many people in the fruit lab group helped with my research. I want to thank the other graduate students in the fruit lab group, Sarah Kostick, Seth Wannemuehler, Elizabeth Blissett, Ashley Powell, Joshua Anderson, and particularly Soon Li Teh, who was a great collaborator and was helpful in editing the figures in this dissertation. Fruit lab undergrad students and short term workers Baylee Miller, Emmi Klarer, Steve- Scofield Opiyo, Hannah Hauan, and Madeline Leslie all helped with copious amounts of phenotyping and sample processing.
