Abstract/ Executive Summary:

An experiment was conducted at Central Station, Dhaka; Manikganj and Kishoreganj to characterize of fourteen accessions of kenaf germ plasm collected from different sources were sown on 16 March, 1998, 21 March, 1998 and 29 March, 1998 respectively along with the check varieties HC-2 and HC-95. 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. The accessions were characterized for their morph-agronomic attributes as per Hibiscus descriptor. Pigmentation data were collected at 60 days after sowing. Plants were harvested at 120 days after sowing and post harvest data were collected. Based on the major yield contributing characters viz. technical height, leaf angle, leaf length, leaf width, petiole length, node number, base diameter of stem, middle diameter of stem, top diameter of stem, core diameter, dry fiber weight and dry stick weight accessions 3778, 4442 and 4625 performed better than the check varieties.

Keywords: Germplasm, Characterization, Disease and pest status, Attributes, yield

Location: Central Station, Dhaka; Manikganj and Kishoreganj

Start Date: 16-03-1998

End Date: 15-07-1998

Program Area: Variety and Species

Commodity: kenaf

Objectives:

1. To evaluate of kenaf germplasm for their morph o-agronomic attributes

2. To find out the disease and pest infestation status of jute plant

Methodology:

The experiment was laid out in RCBD design with three replications. Row to row distance was 30 and plant to plant distance was 5-6 cm in rows. The accessions were sown on 16 March, 1998, 21 March, 1998 and 29 March, 1998 respectively at Central Station, Dhaka; Manikganj and Kishoreganj. Fourteen accessions of exotic kenaf germ plasm collected from abroad along with check varieties HC-2 and HC-95 were sown on 1998. The materials under study were accessions 3759, 3778, 4121, 4139, 4140, 4197, 4198, 4431, 4442, 4443, 4446, 4447, 4624 and 4625. The unit plot size for each accession was 5 rows of 3 m length, spacing 30 cm between rows and 5-7 cm between plants and 1 m between plots. Standard cultural practices were followed. Pigmentation data on stem color, leaf color, vain color, petiole color, stipule color, bud color, and fruit color were collected at 60 days after sowing. 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 fiber weight and dry stick weight were collected. The data were analyzed following standard statistical procedures.

Achievement/Findings:

The accessions were characterized for their morph-agronomic attributes as per Hibiscus descriptor. Pigmentation data were collected at 60 days after sowing. Plants were harvested at 120 days after sowing and post harvest data were collected. Based on the major yield contributing characters viz. technical height, leaf angle, leaf length, leaf width, petiole length, node number, base diameter of stem, middle diameter of stem, top diameter of stem, core diameter, dry fiber weight and dry stick weight accessions 3778, 4442 and 4625 performed better than the check varieties.
