Dr. Ma. Genaleen Diaz is recognized for her outstanding contributions to the genetic analysis of important Philippine crops such as coconut, Lufffa, Momordica and various medicinal plants through techniques that traverse cytogenetics to more advanced techniques of isozyme and DNA markers and microarrays. Her studies have contributed to a better understanding of the diversity, compatibility and phylogenetic relationships of such crops and further elucidation of the differences of makapuno and normal coconut at the molecular level. Her researches have also enriched eight laboratory manuals in genetics and cytogenetics, which she and her co-authors have published and which have benefited many students in the past ten years.
