The book is written on the basis of the authentic practical research experience gained by conducting experiments in laboratory, net-house and field levels. Fourteen jute mutants against jute hairy caterpillar, jute stem weevil, and jute yellow mite were tested. The highest infested plants and leaves were found in the check variety BINADESHIPAT-2 and the lowest were observed in the mutants C-26 and CM-84 in the field. The mutants CM-77, CM-81, CM-102, CM-72, CM-87, CM-63, and BINADESHIPAT-2 were designated as susceptible. The mutants CM-84, CM-74, CM-70, CM-66, CM-96, C-443 and CM-101 were graded as highly susceptible and C-26 was moderately susceptible to jute hairy caterpillar. In case of jute stem weevil, infestations were comparatively low in C-26, except CM-70. Number of knots per plant was highest in BINADESHIPAT-2. All of the mutants/varieties were showed moderate resistant to jute stem weevil. More number of knots was found at the heights of 31-60 and 61-90 cm. However, in jute yellow mite, mutants performed better in comparison to BINADESHIPAT-2.
