Ultimate fibres in tossa jute (Corchorus olitorius L.) and their utilization in selection
- 18 Downloads
An experiment was conducted with 11 indigenous genotypes and two cultivated varieties of tossa jute and studied the length, breadth and length/breadth ratio of ultimate fibre cells. The study indicated the highest mean length of fibre cells in the top part of the stem followed by middle and bottom parts. The mean breadth of fibre cells was notably large in the bottom part with a diminishing trend towards the middle and top parts. Among the genotypes and varieties studied, accession no. 1497 was found to have the highest mean length (3229·5 μ) of fibre cells in the top followed by middle (2488·7 μ) and bottom (1649·9 μ) parts. The highest breadth of fibre cells (20 μ) was observed in accession no. 1493 and the lowest breadth (15·3 μ) was obtained in accession no. 1497 in top part of the stem. The highest length/breadth ratio (211·20) was also observed in accession no. 1497 in top part of the stem.
