Abstract/ Executive Summary:

An experiment was conducted at Jute Agriculture Experimental Station, Manikganj to evaluate for morpho-agronomic attributes, disease and pest status of twenty nine accessions of kenaf (H. cannabinus) along with check varieties HC-2 and HC-25 were sown at on 25 March, 2004. The experiment was sown in a mini plot of 3 meter length of 5 rows for each accession. Row to row distance was 30 and plant to plant distance was 5-6 cm in rows. The unit plot size was 3m x 1.2 m for each accession and plot to plot distance was 1 meter. Pigmentation data, disease and pest infestation data were collected at 60 days after sowing and sowing to harvest respectively. Plants were harvested at 120 days after sowing and post harvest data were collected. The accessions were characterized for their morph-agronomic attributes, disease and pest status as per Hibiscus descriptor. Based on the major yield contributing attributes, disease and pest infestation status accessions no. 3744, 4111, 4639, 4637,5011, 5079, 5081, and 5083 of kenaf out yielded than check varieties.

Keywords: Germplasm, characterization, disease and pest status, attributes, yield

Location: Jute Agriculture Experimental Station, Manikganj, Rangpur and Kishoreganj.

Start Date: 25-03-2004

End Date: 24-07-2004

Program Area: Variety and Species

Commodity: kenaf

Objectives:

To characterize the kenaf germplasm for their morpho-agronomic attributes, diseases and pest infestation status.

Methodology:

The experiment was conducted at Jute Agriculture Experimental Station, Manikganj, Jute Research Regional Station, Rangpur and Jute Research Regional Station Kishoreganj in 2004. The experiment was laid out in RCBD design with three replications. Twenty nine accessions of kenaf germplasm collected from different sources along with check varieties HC-2 and HC-95 were sown on 25 March, 2004. The materials under study were 3744, 4111, 4121, 4202, 4395, 4411, 4427, 4428, 4429, 4627, 4637, 4639, 4643, 4645, 4649, 4715, 4751, 4797, 4815, 4996, 4997, 4999, 5006, 5011, 5045, 5079, 5080, 5081 and 5083. Row to row distance was 30 and plant to plant distance was 5-6 cm in rows. Standard cultural practices were followed. Pigmentation data on stem colour, leaf colour, vain colour, petiole colour, stipule colour, bud colour, and fruit colour were collected at 60 days after sowing. Disease, pest infestation and fibre properties data were collected from sowing to before harvesting period. Plants were harvested at 120 days after sowing and post harvest data on plant height, node number, base diameter of stem, middle diameter of stem, top diameter of stem, core diameter, dry fibre weight and dry stick weight were collected.
