Abstract/ Executive Summary:

The experiment was conducted in the field of JAES, Manikganj to find out the sources of resistant/tolerant accessions against fungal diseases. Twelve-deshi germplasm with 2 check varieties and 7 tossa germplasm with 3 check varieties from gene bank were screened against fungal disease. Out of 15 deshi, only two accessions 469, 955 and two varieties CVL-1 BJC-83 were found tolerant against stem rot.

Keywords: Investigate, Jute,Kenaf, Mesta,resistance, Fungal diseases

Location: JAES, Manikganj

Start Date: 30-03-2005

End Date: 30-10-2005

Program Area: Pest Management

Commodity: Mesta, kenaf, Jute

Objectives:

1.To Screening of germplasm from different sources and selection under heavy inoculation potential in the field is an effective method for isolation of resistant gene.

2.To recommend the promising lines for utilization in future research program.

Methodology:

Germplasms of Corchorus sp. kenaf and Mesta 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 replication. 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).
