摘　　要：Jute is the golden fiber crop of Bangladesh. Viral and Nemic diseases are the major threats to fiber crops, and the fiber yield decreases drastically as the disease infection increases. An experiment was conducted to screen and evaluate ten Jute and allied fiber varieties i.e. BJRI Kenaf-4, BJRI Kenaf-3, HS-95 (Kenaf), HS-24 (Mesta pat), HC-2 (Kenaf), BJRI Deshi pat-8, BJRI Deshi pat-7, BJRI Deshi pat-5, BJRI Deshi pat-6 and CVL-1 against mosaic virus and root-knot nematode disease. It was done in RCBD design with three replications at Sher-e-Bangla Agricultural University (SAU) central farm, Dhaka-1207, from June 2018 to March 2019. In the case of viral infection, variety 4 (HS-24 (Mesta pat)) showed maximum virus incidence (23.11%), whereas variety 2 (BJRI Kenaf-3) had no virus evidence. The most susceptible nematode-infected variety was found in varieties 5 (HC-2 (Kenaf)) and 9 (BJRI Deshi pat-6), which showed 80% incidence, whereas variety 2 (BJRI Kenaf-3) was highly resistance. The growth and yield results showed a significant (0.05%) reduction of plant height (cm) and fiber weight (t/ha) with an increase in the percentage of virus and nematode incidence against all varieties. The highest fiber weight (1.47 t/ha) and the lowest viral (0%) and nemic infection (0%) were found in variety 2 (BJRI Kenaf-3), which showed better performance compared to other varieties. These results revealed that variety 2 (BJRI Kenaf-3) had the best variety in the present study.Jute is the golden fiber crop of Bangladesh.
