In autotetraploid of jute (Corchorus capsularis) coefficient of realization of quadrivalents was found to be very high (0.75). A PMC on an average found to contain 0.77 univalent, 2.56 bivalents, 0.35 trivalents, and 5.26 quadrivalents. All types of quadrivalent configurations were observed of which figure of eight were most frequent (24.59%). Chiasma frequency per chromosome were found to be 0.97 and 0.93 in diploid and tetraploid respectively.
