Dr. Dolores Ramirez is recognized for her researches in biochemical genetics and cytogenetics. She has been working on the genetic systems controlling the makapuno endosperm of coconut; the genetics of chemical resistance factors against Cercospora kex leaf spot; and the cytogenetics of the hybrids of rice with related wild species. Dr.Ramirez was holder of the SEARCA Professorial Chair for Genetics (1974-76), and recipient of the Gregorio Y. Zara award in basic research (1976), Rizal Pro Patria award for outstanding achievement in science (biochemical genetics) (1981), and UP Professorial achievement award in agriculture (1985).
