The greater yam (Dioscorea alata L.) is the most widely distributed yam species in the world. In India it is grown in AP, MP, CG, Orissa, Kerla, Rajsthan and many other states for its tuber. Field experiment was conducted during Kharif season of 2020-21 at AICRP on tuber crops project, Saheed Gundadhur College of Agriculture & Research Station, IGKV, Jagdalpur, C.G to determine and evaluate the growth, yield and quality performance of greater yam genotypes under South Chhattisgarh condition. Treatments comprised of 8 different genotypes and the experiment was laid out in randomized complete block design with three replications. The evaluation performance of different genotypes was assessed by analyzing data on yield, yield attributing and quality parameters. Results demonstrated that there is significant difference on performance of different greater yam genotypes. Based on the mean performance, Sree Karthika recorded for higher dry matter and starch %, TGy 17-10 observed maximum tuber yield per plant and per hectare (3.19 kg & 39.42 t) followed by Sree Karthika (2.39 kg & 29.55 t). The studies suggest that it can possible to isolate superior genotypes during the selection process based on evaluation.
