Academic and Research Achievements: Gupta extensively worked on different areas of plant cytogenetics, induced mutations, and quantitative genetics utilizing both classical and molecular approaches (mainly in cereals and legumes). Initially, while at Gorakhpur and Meerut, he conducted studies on chromosome status in several groups of plants including grasses, ornamentals and legumes, but later, during his PhD work (1964-67), he studied homoeologous relationships between wheat and rye chromosomes using wheat rye alien substitution lines. He also conducted research in the area of induced mutations and biometrical genetics and release of a mutant variety in mungbean (MUM-2). More recently, he has established a wheat biotechnology laboratory at Meerut and conducted research leading to detection of marker-trait associations and use of marker-aided selection for a number of traits in bread wheat. He has authored more than a dozen textbooks and published over 350 research articles, and mentored a large number of students including seventy PhD students.
