Abstract/ Executive Summary:

A total of fifteen accessions of Corchorus olitorius Linn was characterized based on morpho-agronomic traits The highest plant height was obtained from the accession no.3790 (3.65m). The highest base diameter was obtained from the accession no.3816 (22.5mm). The highest leaf length (19cm), leaf width (10.6 cm) was obtained from the accession no. 3718. The highest petiole length was obtained from the accession no.3816 (9.9cm).The highest node number (65) and fibre yield(39 gm/plant) was obtained significantly from the accession no.3790. The accession no.3790 and 3802 gave higher fibre yield and showed moderately resistance to mite and disease infestation and water logging condition.The accession no.7419 and 3786 showed early maturing characters and gave better quality fibre.

Keywords: Accession, Corchorus olitorius, Morpho-agronomic traits

Location: Jute Agriculture Experimental Station (JAES), Manikganj and three regional stations (Rangpur, Chandina, Faridpur)of Bangladesh Jute Research Institute (BJRI).

Start Date: 15-04-2000

End Date: 31-12-2002

Program Area: Variety and Species

Commodity: Jute

Objectives:

To characterize the morpho-agronomic traits of fifteen accessions of tossa jute

Methodology:

The experiment was conducted at Jute Agriculture Experimental Station (JAES), Manikganj and three regional stations (Rangpur, Chandina, Faridpur)of Bangladesh Jute Research Institute (BJRI)with three replications following RCB design having unit plot size of 3.0m x 0.6m. The seeds of the accessions along with the controls OM-1, O-9897 and O-4 were sown in mid April. Records on plant height, base diameter, green weight with and without leaves, leaf length, leaf breadth, leaf angle, petiole length, number of nodes per plant and dry fibre weight were taken according to IJO descriptor. Standard cultural practices were followed. The crops were harvested on an average of 120 days of plant age. Recorded data were analyzed following standard statistical procedures.

Achievement/Findings:

The accession no.3790 and 3802 gave higher fibre yield and showed moderately resistance to mite and disease infestation and water logging condition.The accession no.7419 and 3786 showed early maturing characters and gave better quality fibre. These accessions would be used for variety development programme.
