Online published on 2 May, 2015. Abstract Twenty seven genotypes of Corchorus olitorius L. having diverse origin were sown in Randomized Block Design with three replications, in four successive growth seasons from 2007 to 2010 during pre-kharif season at the instructional farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal. From the cluster analysis the genotypes JRO 128 and JRO 878 in cluster VII, OIN 046, OIN 217, OIN 572, OIN 574, OIN 576, OIN 580 and JRO 620 in cluster VI and OIJ 015, OIN 028, OIN 257 and OIJ 267 in cluster V were found to be distinct with the desirable characteristics and may be incorporated in breeding programme to improve fibre yield and quality. The characters basal diameter, green weight and fibre % appeared to be predominant consideration for fibre yield as they exhibited highly significant positive correlation with fibre yield, among themselves and exerted positive direct effect on fibre yield. Therefore, selection based on these characters may bring out desired improvement towards enhancing the fibre yield in tossa jute.
