Abstract/ Executive Summary:

The present study was conducted at Jute Agricultural Experimental Station (JAES) at Manikganj in 2017 to identify some selected advanced lines against stem rot, the major fungal disease of jute in artificially inoculated sick beds under field conditions. Two separate experiments for capsularis and olitorius lines were sown in 3m lines with 3 replications. For capsularis, acc. BJC 2197, CVL-1 and BJC-7370 had moderately resistant character (MR), accession 2149, 2403, 2197 and 2498 had susceptible reaction (S) and accession 2149 had highly susceptible (HS) against stem rot disease in artificially inoculated sick bed under field condition. Findings revealed that, the olitorius acc.- 2496, 2499, 3820 and variety O-9897 had a moderately resistant reaction and accessions 2043, 2481, 2483, 2712, 2731, 2419, 2478, 2727, 2732 had a susceptible reaction against stem rot in artificially inoculated sick bed under field condition.

End Date: 30-09-2017

Program Area: Pest Management

Commodity: Jute

Objectives:

The present study was conducted to identify resistant lines of some selected advanced lines against the fungal disease to develop disease-resistant variety

Methodology:

Methodology: Two separate experiments for capsularis and olitorius lines were conducted at JAES, Manikganj of BJRI. Promising lines of capsularis and olitorius along with recommended varieties CVL-1 and O-9897 were used as control. Seeds were sown in 3m lines with three replications. Before sowing the seeds, the field was inoculated with the artificial inoculam of Macrophomina phaseolina. Normal agronomical practices was done and fertilizer doses were applied as per recommendation. No plant protection measure was taken till the harvesting stage to facilitate the natural disease infestations. The disease samples were collected to identify the pathogen. The scale used for measuring fungal diseases as follows.

Scale: Resistant (R) – 0-10%, Moderately resistant (MR) – 10-20%, Susceptible (S) – 20-30% , Highly Susceptible (HS) - > 30%.

Materials used for capsularis germplasm. Acc. 2197, 2149, 2403, 2498, BJC-2197, BJC-7370 and CVL-1 and for olitorius, the accessions were Acc.- 2043,2478, 2481 2483, 2496,2499,2712, 2731, 2727, 2732, 3820, 2419 with variety O-9897.
