Abstract/ Executive Summary:

The aim of this experiment is to select out tossa jute mutant lines with higher fiber and stick yields, and lower lignin and higher cellulose contents. For this, dry seeds of O-9897 were irradiated with 400, 500, 600, 700 and 800 Gy doses of gamma rays and selection based on the mentioned objectives during M₂ and M₃ generations. M₄ seeds were sown in April 2011 at BINA farm, Mymensingh in separate plots dose wise. Spacing between plants was 7-8 cm within rows of 30 cm apart. Recommended doses of fertilizers, cultural and intercultural practices were followed as and when necessitated. Based on plant height, base diameter and stem color 10 plants from 400 Gy, 4 from 500 Gy, 7 from 600 Gy, 4 from 700 Gy and 9 from 800 Gy doses were selected for preliminary yield trial during 2012.

Commodity: Jute

Objectives:

Objective of this study was to select out tossa jute mutant lines with higher fiber and stick yields, and lower lignin and higher cellulose contents.

Methodology:

The experiment was conducted at the Experimental field of Genetics and Plant Breeding Division, Bangladesh Institute of Nuclear Agriculture, Mymensingh to select out tossa jute mutant lines with higher fiber and stick yields, and lower lignin and higher cellulose contents. For this, dry seeds of O-9897 were irradiated with 400, 500, 600, 700 and 800 Gy doses of gamma rays and selection based on the mentioned objectives during M₂ and M₃ generations. M₄ seeds were sown in April 2011 at BINA farm, Mymensingh in separate plots dose wise. Spacing between plants was 7-8 cm within rows of 30 cm apart. Recommended doses of fertilizers, cultural and intercultural practices were followed as and when necessitated. Based on plant height, base diameter and stem color 10 plants from 400 Gy, 4 from 500 Gy, 7 from 600 Gy, 4 from 700 Gy and 9 from 800 Gy doses were selected for preliminary yield trial during 2012.
