Abstract/ Executive Summary:

An experiment was conducted at Jute Agriculture Experimental Station, Manikganj and Chandina to evaluate for morpho-agronomic attributes for disease and pest tolerance of twenty six tossa jute germplasm collected from different sources were sown on 6 April, 2000 along with the check varieties O-9897 and BJRI Tossa pat-4. The experiment was laid out in RCBD with three replications. The length of line of was 3 meter. Row to row distance was 30 and plant to plant distance was 5-6 cm in rows. Pigmentation data were collected at 60 days after sowing. The accessions were characterized for their morph-agronomic attributes as per Corchorus descriptor. Plants were harvested at 120 days after sowing and post harvest data were collected. Accessions showed wide ranges of variability for eleven major traits. Characterization was made for five major yield contributing characters. Significant differences were observed only for plant height at Chandina. But at Manikganj, all the characters showed insignificant differences. Based on the major yield contributing characters accessions 4327, 4695 and 4739 performed better than the check varieties.

Location: Jute Agriculture Experimental Station, Manikganj and Chandina

Start Date: 06-04-2000

End Date: 05-08-2000

Program Area:

Commodity: Jute

Objectives:

To evaluate some tossa jute germ plasm as per Corchorus Descriptor for their morpho-agronomic attributes, disease and pest tolerance of selected tossa jute (C. olitorius) germ plasm.

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 6 April, 2000 with check varieties O-9897 and BJRI Tossa pat-4. Other standard cultural and intercultural practices were followed. Pigmentation data were collected at 60 days after sowing. Disease and pest infestation data were collected from sowing to before harvesting period. Plants were harvested at 120 days after sowing and post harvest data were collected. Twenty six accessions of tossa jute viz. 4148, 4309, 4327, 4454, 4507, 4548, 4583, 4689, 4694, 4695, 4719, 4739, 4740, 4756, 4793, 4828, 4840, 4852, 4890, 5001, 5009, 5088, 5091, 5092, 5093 and 5094 were characterized.

Achievement/Findings:

The accessions were characterized for their morph-agronomic attributes as per Corchorus descriptor. Plants were harvested at 120 days after sowing and post harvest data were collected. Accessions showed wide ranges of variability for eleven major traits. Characterization was made for five major yield contributing characters. Significant differences were observed only for plant height at Chandina. But at Manikganj, all the characters showed insignificant differences. Based on the major yield contributing characters accessions 4327, 4695 and 4739 performed better than the check varieties.
