Abstract/ Executive Summary:

In this experiment fibre bearing potentiality of 47 accessions of white jute along with cultivar CVL-1 as check variety was assessed through studies of anatomical characters such as bark thickness, number of phloem pyramid trapezoid, area of phloem pyramid, number of layer, number of fibre bundle. Significant differences among the treatments were observed for bark thickness, number of pyramid and area of pyramid. Previous studies indicated that bark thickness and area of pyramid are directly and positily correlated with fibre yield. Accession number 875, 1486, 1489, 2088 and 4729 gave higher bark thickness coupled with higher area of pyramid than check variety CVL-1 indicating that they have higher fibre bearing potentiality.

Keywords: Screening, White jute, Accession

Location: Central Jute Agricultural Experiment Station (JAES), Manikganj

Start Date: 25-03-2004

End Date: 31-12-2004

Program Area: Variety and Species

Commodity: Jute

Objectives:

To isolate higher fibre bearing potentiality genotypes through anatomical studies.

Methodology:

For studying anatomical characters 3 inches long segments was cut from the middle parts of each of the selected plant at the age of 110 days. 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). Bark diameter, Bark thickness,Number of trapezoids/section, Area of trapezoid/section (μm), Number of layers/ trapezoid, Number of bundles/trapezoid , Length, breadth and length: breadth ratio were calculated for three plants of each accession under microscope. So, we can easily isolate higher fibre bearing potentiality genotypes through anatomical studies i.e. fibre compactness per unit area of plant bast.
