Abstract/ Executive Summary:

Fourty lines of deshi and tossa jute were screened in fields against the major fungal pathogenas i.e Macrophomina Phaseolina, Botryodiplodia theobromae, Sclerotium rolfsii. Out of 41 lines/accessions of gene bank, 14 lines were found to resistant ( R ), 18 lines were moderately resistant (MR) and remaining 9 linnes were found susceptible (S) and Highly susceptible(HS ).

Keywords: Host, Fungal, Diseases, Sick-bed

Location: JAES,Manikganj

Start Date: 15-03-2006

End Date: 30-12-2006

Program Area: Pest Management

Commodity: Jute

Objectives:

1.To find out of germplasm from different sources against fungal pathogens.

2.To recommended the promising lines utilization for future research.

Methodology:

A total of 41 lines of Corchorus sp. were screened against fungal diseases.Inoculation was prepared by growing cultures of the Macrophomina phaseolina on the wheat husk or on old jute seed powder medium.This pure culture was applied in the soil before final land preparation to build up inoculation potential. The seeds of each treatment was sown in a single row 3m long following RCBD with three replications. At 45 and 60 days age of the plants inoculum was applied again in each row. To build up more inoculum potential rouged out diseased plants was spread into the soil time to time. Intercultural operations and application of fertilizer was done as usual. Disease reaction was evaluated on the percentage of affected plant in each line and grouped as Resistant ( R ), Moderately resistant ( MR ), Susceptible ( S ) and Highly susceptible (HS).
