Abstract

Sixty yam bean accessions were evaluated for tuber yield and biochemical characters at Central Tuber Crops Research Insititute, Thiruvananthapuram, India. The mean yield data of two years’ preliminary yield trial showed that the tuber yield ranged from 9.1 to 27.8 t ha  -1. Dry matter of tuber varied from 9.0 to 15.0%. The starch content ranged from 3.0 to 6.0% and sugar varied from 2.5 to 4.0%. The results of the advanced yield trial conducted for three years with 16 accessions selected from preliminary yield trial indicated that six accessions recorded an yield of >25.0 t ha-1. Highest yield of 29.0 t ha-1 was observed in the accession EC 100566.
