Abstract

Field experiments were conducted during 2006 to 2010 at Central Experiment Station, Wakawali,  Maharashtra to evaluate the performance of six genotypes of greater yam viz., Sree Roopa, Da-11,  Da.25, Da.168, Da.199 and Konkan Ghorkand for yield and quality. The trial was conducted in  randomized block design with four replications. The pooled results showed that the genotype Da-199  produced the highest tuber yield of 29.29 t ha-1 and average tuber weight of 1.62 kg, which was  significantly superior to all other genotypes. In multi-locational trials, it also produced significantly the  maximum tuber yield of 21.39 t ha-1 over the rest of the genotypes in four different locations. Cultivation  of Da.199 generated the maximum net return of ` 2,42,078 ha-1 and B:C ratio of 1.70. Among all  the genotypes, Konkan Ghorkand and Da-199 had maximum score for all organoleptic characters.
