Zonal Yield Trial with M9 Mutant Lines of Tossa Jute

Dr. M. A. K. Azad
Chief Scientific Officer
Plant Breeding Division, Bangladesh Institute of Nuclear Agriculture, Mymensingh

Abstract/ Executive Summary:

The aim of this experiment is to develop tossa jute variety(s) with higher fiber and stick yields and lower lignin content with three mutant lines following RCB design with three replications. The parent O-9897 was also included in this experiment. Seeds were sown on 16-24 April 2011 at farmer’s field at Mymensingh, Faridpur and Magura and BINA sub-station farms at Magura and Rangpur. It appears that the mutant O97/90/72-3 had significantly taller plant height at all locations than the check variety O-9897 except farmer’s field at Magura. At farmer’s field of Magura none of the characters had shown significant difference amongst the mutants and the check variety. In contrast, base diameter of O97/90/72-3 had shown significant difference at Rangpur and Faridpur locations. Green weight with and without leaves of this mutant were also higher than the check variety at all locations despite having not significant difference at Rangpur and Mymensingh. Fiber weight of this mutant did not show significant difference with the check variety. Contrarily, stick weight was significantly higher than the check variety. Finally, the mutant O97/90/72-3 will be put into on-farm and on-station trials again at different jute growing areas of Bangladesh, next year to confirm its fiber and stick yield potentiality.

Keywords: Zonal yield trial, M9 mutant lines, tossa jute

Location: Farmer’s field at Mymensingh, Faridpur and Magura and BINA sub-station farms at Magura and Rangpur.

Start Date: 16-04-2011

End Date: 23-07-2011

Program Area: Variety and Species

Commodity: Jute

Objectives:

To develop tossa jute variety(s) with higher fiber and stick yields and lower lignin content.

Methodology:

The aim of this experiment is to develop tossa jute variety(s) with higher fiber and stick yields and lower lignin content with three mutant lines following RCB design with three replications. The parent O-9897 was also included in this experiment. Seeds were sown on 16-24 April 2011 at farmer’s field at Mymensingh, Faridpur and Magura and BINA sub-station farms at Magura and Rangpur. Spacing between plants was 7-8 cm within rows of 30 cm apart. A unit plot size was 5.0 m × 4.0 m. Recommended doses of fertilizers, cultural and intercultural practices were followed as and when necessitated. Data on plant height, base diameter, green weight with and without leaves, dry fiber weight and stick weight were recorded after harvest. Green weight without leaves, fiber weight and stick weight were gathered from an area of 5 m2 and later converted to t ha^-1. Finally, these data were subjected to proper statistical analysis.
