Abstract/ Executive Summary:

The present study was conducted to know the status of different seed borne pathogens and their percentage in seed samples of jute, kenaf and mesta collected from different stations of BJRI. All together 54 seed samples belonging breeder, foundation and TLS of different varieties were collected from different regional and sub-stations of BJRI. Seeds samples were examined following the rules of ISTA in the laboratory of Plant Pathology Department of BJRI. The fungal pathogens Macrophomina phaseolina (5%) was recorded in BJC-7370 collected from Pakhimara station of BJRI in TLS, Colletotrichum corchori (18%) recorded in CVL-1 and BJC-7370 collected from Manikgonj and Rangpur in Breeder seed samples and Botryodiplodia theobromae (6%) in O-72 collected from Monirampur station of BJRI. The Fungus Fusarium was found in most of the seed samples and prevalence of the fungi ranged from 1-73%. The highest parentage of Fusarium (73%) and number of total pathogen (73) were reordered in HC-95 collected from Kishoregonj regional station. Findings revealed that germination varied from variety to variety collected from different stations and ranged from 25-98% and had negative correlation with presence of % fungi for each seed sample.

Commodity: Mesta, Jute, kenaf

Objectives:

To know the status of different seed borne pathogens and their percentage in seed samples of jute, kenaf and mesta collected from different stations of BJRI.

Methodology:

Seed samples of breeder, foundation and TLS were collected from different jute growing zones of Bangladesh and tested by blotter method in the laboratory of Plant Pathology Department, BJRI. After 10 days of incubation, the seeds were examined under stereomicroscope for detection of different fungal pathogens. Percentage of seed borne infections were determined.
