Abstract/ Executive Summary:

The experiment was conducted in the field of JAES, Manikganj to find out germplasms against root-knot diseasesCapsularis. Only three accessions # 2147, 2727, 3820 were found tolerant against root knot disease at Nashipur farm.

Keywords: Resistant,Jute,allied fibre crops, Root-knot,Disease

Location: JAES,Manikganj

Start Date: 30-03-2008

End Date: 30-10-2008

Program Area: Pest Management

Commodity: Jute

Objectives:

1.To find out germplasms against root-knot diseases.

2.To help the breeders to develop the resistant varieties against root-knot

Methodology:

The plants were sown in sterilized soil and was inoculated with pure culture of Meloidogyne sp. at proper age of the plant. Preparation of inoculation: Tomato plants previously were grown in nematode free soil was inoculated by adding nematode infected roots of jute. After 60 days, egg mass of nematodes were collected from tomato root and incubated in a watch glass at 25^oC . Selected germplasm materials were inoculated with the newly hatches larvae suspended in sterilized water ( 50 larvae/ml). Each plant was inoculated with 20 ml of this suspension.Following records were kept: 1) Date of sowing of tomato plants 2)Date of sowing of germination materials 3) Date of inoculation 4) Observation of root-system of each material for gall formation time to time.
