Abstract/ Executive Summary:

This experiment was carried out with six breeding lines namely Ped 11/04, (O-043-7-9), Ped-5/04(O-0412-9-4), Ped5/05 (O-0512-6-2), O-053-15-2, O-049-1-3, OM-1MG1 and variety O-9897. Materials were grown at Manikganj station in three meter lines with three replications of each. Standard agronomic practices were followed. The highest bark diameter was observed in O-049-13 followed by O-9897. O-9897 gave the highest bark thickness among the tested lines. Ped 5/04 (O-0412-9-4, Ped11/04 (O-043-7-9) and O-049-1-3 performed better for number of trapezoids. Line O-049-1-3 (10.62sq. mm) gave higher area of trapezoid followed by O-9897 which indicated both the lines will also be given higher fibre yield in field condition.

Start Date: 15-03-2013

End Date: 15-07-2013

Program Area: Variety and Species

Commodity: Jute

Objectives:

The production of jute means the production of fibre. Jute fibre is anatomically the secondary phloem cells which are accumulated during growth of plant and arranged in regular fashion of fibre wedges. So bark thickness, number and area of phloem wedge of the stem directly contribute to fibre yield. Whilst the quality of fibre is dependent on some chemical and physical parameters. Among them length breadth ratio of fibre cells are of immense importance. The higher length breadth ratio imparts better spinnability. Jute fibre is not a single fibre, it is composed of many ultimate fibres and commercially called multicellular fibre. The tensile strength, twisting capacity etc. depends on the individual fibre (ultimate fibre), and the quality of fibre depends upon the length and length breadth ratio of these ultimate fibres. The more length breadth ratio, the superior quality of fibre. The higher length breadth ratio imparts better spinnability and thus involves better quality of fibre. Studies of these anatomical traits will be undertaken to assess the anatomical feature of some promising lines of tossa jute.

Methodology:

Three inches long pieces of stem were cut from the middle part of each selected plant of 110 days after sowing. These materials were preserved in Formalin- Aceto- Alcohol (FAA) solution (10 ml of Formalin, 5ml of 85% glacial acetic acid and 85 ml of 70% alcohol). The preserved sample parts were taken out and washed. About 20-25mm thick transverse sections (TS) were done with the help of a microtome machine for preparing slide. The slides were studied under compound microscope (4x10 magnifications) and data recorded for bark thickness, number and area of phloem wedges, number of fibre bundle layers and number of fibre bundles per section.

Achievement/Findings:

The results revealed that the highest bark diameter was observed in O-049-13 followed by O-9897. O-9897 gave the highest bark thickness among the tested lines. Ped 5/04(O-0412-9-4, Ped 11/04 (O-043-7-9)and O-049-1-3 performed better for number of trapezoids. Line O-049-1-3 (10.62sq. mm) gave higher area of trapezoid followed by O-9897 which indicated both the lines will also be give higher fibre yield in field condition.
