Abstract/ Executive Summary:

A study was carried out at JAES, Manikganj in 2006. The materials were sown in three meters lengh and two lines for each germplasm following RCBD method. It was observed that root-knot nematode attacks kenaf plant mostly in August – September and not a single accession was free from nematode attack while mesta accessions were free from root-knot nematode attack. On the other hand, none accessions of kenaf and mesta were affected by spiral borer.

Keywords: Root-knot, Spiral borer, Kenaf and Mesta, Germplasm

Location: JAES, Manikganj

Start Date: 17-04-2006

End Date: 28-08-2006

Program Area: Variety and Species

Commodity: Mesta

Objectives:

1)To select genotypes for high yielding and desirable traits from gene bank collection.

2) To find out any germplasm which is diseases and pest resistant from collected gene bank.

Methodology:

Bangladesh Jute Research Institute has 5936 germplasms of jute and allied fibre yielding crop of both indigenous and exotic origin. These germplasm materials have wider gene pool with different types of biotic and abiotic tolerance characters. Thirty Kenaf and 15 Mesta accessions and check varieties HC-2, HC-95 and HS-24 were grown at JAES, Manikganj during the year 2006 having 2 lines of 3m long row. After 45 days of plant age 2-3 plants from each row were up rooted at 15 days interval and examined for root-knot nematode infestations.
