Abstract/ Executive Summary:

An experiment was conducted at Jute Agriculture Experimental Station, Manikganj to estimate genetic divergence of thirty deshi jute germplasm collected from different sources were sown on 13 March, 2007 along with the check varieties CVL-1 and CVE-3. 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. Wide range of diversity was observed among the accessions. All the genotypes were grouped into five clusters. Diversification observed in leaf colour, stem colour, petiole colour, plant technical height, dry core weight and days to first flowering. Pigmentation data were collected at 60 days after sowing. Plants were harvested at 120 days after sowing and post harvest data were collected. The accessions were characterized for their morph-agronomic attributes as per Corchorus descriptor. Considering genetic diversity and other 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 fibre weight and dry stick weight accessions 859, 864, 877, 948, 1489, 1947, 1958, 1939 and 1973 performed better in most of the cases than the control varieties CVL-1 and BJC-7370.

Keywords: Germplasm, Divergence, Characterization, Yield

Location: Jute Agricultural Experimentation Station, Manikganj

Start Date: 13-03-2007

End Date: 12-07-2007

Program Area: Variety and Species

Commodity: Jute

Objectives:

To study the genetic divergence of some deshi jute germ plasm.

Methodology:

The experiment was conducted to study the genetic divergence of some deshi jute germ plasm at Jute Agriculture Experimental Station, Manikganj in 2007. Thirty accessions of selected deshi jute germ plasm collected from home and abroad along with check varieties CVL-1 and CVE-3 were sown on 13 March, 2007. The materials under study were 858, 859, 862, 863, 864, 865, 877, 880, 890, 924, 925, 927, 935, 941, 943, 945, 948, 957, 1482, 1483, 1489, 1490, 1491, 1520, 1800, 1920, 1947, 1958, 1973 and 2040. The experiment was laid out in RCBD design with three replications. Length of line was 3 m, row to row distance was 30 cm and plant to plant distance was 5-6 cm in rows. 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 procedure.
