The present investigation was undertaken to study the cytological effects of Ethylamine on Jute (Corchorus olitorius L Variety JRO-632) obtained from Jute Agricultural Research Institute (ICAR), Barrackpore, West Bengal, India, since no attempt has been made in this direction so far Presoaked seeds of jute were treated with 1% Ethylamine for 6 hours Chromosome analysis from root tip cells revealed a number of aberrations, like fragments, clumping, random grouping of chromosomes, condensed chromosomes, erotion of chromosomes, stickiness, diploidization and polyploidy were observed in metaphase stage and fragment, lagging, early and late separations were observed in anaphase stages. Micronuclei were also visible The principal objective of the above mentioned study lies in the fact that in mutation studies with jute if chromosome aberrations and sterility percentages could be reduced and mutation ftequancy increased then it would be of great significance and commercial importance.
