Thirty indigenous genotypes of Dioscorea (Dioscorea bulbifera) collected from twelve districts of Chhattisgarh viz., Bastar, Korba, Dhamtari, Rajnandgaon, Surguja, Kondagaon, Sukma, Balod, Narayanpur, Kanker, Dantewada and Bijapur. The collected genotypes show wide range of variability in morphological characteristics. More variability was recorded in genotypes collected from Sukma district of Chhattisgarh followed by Bijapur and Kanker district. Petiole colour varied from all green with purple at both ends and all purplish green with purple at both ends with the frequency of 26.67% and 73.33% respectively. Petiole length in correlation to leaf blade is characterized in to three categories i.e. short, medium and long with 13.33%, 13.33% and 73.33% respectively. Highest frequency (50%) was recorded as rough aerial tuber texture followed by wrinkled (40%) and lowest frequency (10%) as smooth. However, all the genotypes of Dioscorea bulbifera exhibits cordate leaf shape, opposite leaf position, entire leaf margin, acute apex shape and the distance between lobes is intermediate.
