This study maps the scholarly landscape of Chakhao (black rice) research from Manipur during the period 2000–2020 through a comprehensive citation analysis of postgraduate theses in plant breeding and genetics. A total of 490 citations were examined to identify patterns in authorship, journal preference, thematic focus, and the dispersion of literature. The analysis reveals that research on Chakhao has evolved from traditional agronomic and descriptive studies to more advanced investigations in genetics, nutritional profiling, and functional food potential. Journals such as Plant Genetic Resources and Symbiosis formed the core zone of literature, while Bradford’s Law confirmed a 2:3:5 scattering pattern across three productivity zones. The rise of multi-authored works during the later years indicates expanding collaboration and interdisciplinary engagement. Overall, the findings highlight a growing and diversifying body of scholarship that reflects increasing global interest in Chakhao as a culturally significant, nutritionally rich, and economically valuable indigenous rice variety. The results provide a useful foundation for future bibliometric, molecular, and interdisciplinary studies aimed at the conservation and sustainable utilization of this unique heritage crop.
