Abstract/ Executive Summary:

Multilocation trial of the new breeding line of Kenaf CPI-72126 was conducted at Manikganj, Rangpur, Chandina, Faridpur, Kishrorganj, Patuakhali and Monriampur along with the varieties HC-2 and HC-95 (Check) during the year 2009 with a view to develop a new variety producing high biomass containing, rapid growth and year round cultivation characters CPI-72126(1) showed the best performance against the check varieties in respect of plant height, base diameter, green weight without leaves, fibre weight and stick weight in all the stations. CPI-72126 gave the highest fibre yield (4.77 t/ha) significantly at Faridpur where the check variety HC-95 gave (4.75 t/ha) fibre yield. CPI-72126 also gave the highest plant height (3.8m), base diameter (22.41 mm) and stick weight (13.5 t/ha) at the same station. This breeding line was proposed for registration as a new variety in 2009.

Keywords: Zonal yield trial,Breeding line of kenaf

Location: Manikganj, Rangpur, Chandina, Faridpur, Kishrorganj, Patuakhali and Monriampur

Start Date: 20-04-2009

End Date: 21-08-2009

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 conducted at Manikganj, Rangpur, Chandina, Faridpur, Kishrorganj, Patuakhali and Monriampur along with the varieties HC-2 and HC-95 (check) during the year 2009 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.

Achievement/Findings:

Under this experiment, CPI-72126(1) showed the best performance against the check varieties in respect of plant height, base diameter, green weight without leaves, fibre weight and stick weight in all the stations. CPI-72126 gave the highest fibre yield (4.77 t/ha) significantly at Faridpur where the check variety HC-95 gave (4.75 t/ha) fibre yield. CPI-72126 also gave the highest plant height (3.8m), base diameter (22.41 mm) and stick weight (13.5 t/ha) at the same station. This breeding line was proposed for registration as a new variety in 2009.
