Abstract/ Executive Summary:

The breeding line of kenaf CPI-72126 was developed from an Australian accession number CPI-72126 by pure line selection. Demonstration trial of the new breeding line of Kenaf CPI-72126 was conducted at Manikganj, Rangpur, Faridpur, Chandina, Tarabo and Monirampur along with recommended varieties HC-2 and HC-95 (check). CPI-72126 performed better against the check varieties in respect of plant height, base diameter, fresh weight with and without leaves, sun dry weight, dry stick weight and dry fibre weight.

Keywords: Zonal yield trial, Breeding line, Evaluate, Kenaf

Location: Manikganj, Rangpur, Faridpur, Chandina, Tarabo and Monirampur

Start Date: 18-04-2005

End Date: 28-08-2005

Program Area: Variety and Species

Commodity: kenaf

Objectives:

To evaluate fibre yield, quality, adaptability and overall suitability of Kenaf advanced lines at farmer’s field in different regions as well as on stations.

Methodology:

The breeding line CPI-72126/1 of Kenaf suitable for year round cultivation was developed from an exotic germplasm (Australian accession number CPI-72126) by pure line selection. It out yielded the control varieties like HC-2 and HC-95. Multilocation trial of the new breeding lines of kenaf CPI-72126/1 was under taken at Manikganj, Rangpur, Faridpur, Chandina, Tarabo and Monirampur along with the varieties HC-2 and HC-95 (check) during the year 2005 with a view to develop a new vareity producing high biomass containing rapid growth and year round cultivation characters. The experiments were carried out in a Randomized Complete Block Design with three replications having unit plot size of 4.5m x 3.0m= 13.5 sq. m. and farmers plot is 5 decimal x 2= 10 decimal. The seeds were sown in mid April and harvested in Mid-August. Data were recorded on plant population at harvest, plant height, base diameter, green weight with leaves, green weight without leaves, fibre weight and stick weight. Proper intercultural operations and agronomic practices were done for raising plants properly.
