Abstract/ Executive Summary:

Three lines of kenaf namely KE-1, KE-2 and KE-3 were isolated for their early maturing characters and one line (purple stem) for its high resistance to disease and pest. These line were tested in 2005 at two locations JAES, Manikganj and Faridpur. Necessary data such as plant height, base diameter fresh weight with and without leafs, sundry weight, fibre weight and stick weight were taken. It was observed that at JAES, Manikganj only the kenaf line KE-3 showed better performance (25.60g/plant) than the recommended variety HC-95 (19.50 g/plant). At Faridpur, the breeding lines KE-1 (46 g/plant), KE-2 (39 g/plant) and PS-1 (40 g/plant) showed better performance than the recommended variety HC-95 (38 g/plant) in respect of plant height, base diameter, fresh weight, sundry weight and fibre weight which are statistically significant.

Keywords: Advanced yield trial, Early maturing, Kenaf, Characteristics

Location: JAES, Manikganj and Faridpur

Start Date: 18-04-2005

End Date: 28-08-2005

Program Area: Variety and Species

Commodity: kenaf

Objectives:

To develop new Kenaf varieties having characteristics of early maturing but quick growing.

Methodology:

Three lines 1641/A (KE-1), 1641/B (KE-2) and 1641/C (KE-3) of kenaf were isolated for their early maturing character and one line (purple stem) for its high resistance to disease and pest. These lines were tested in 2005 at Manikganj and Faridpur stations along with recommended variety HC-95 as check in a Randomized Complete Block Design with three replication having unit plot size of 3.0m x 4.0m=12 sq. m. The seeds were sown in mid March and harvested in Mid-August. Data were recorded on dates to sowing, germination,first flowering plant population at final thinning and at harvest, plant height, base diameter, green weight with leaves, green weight without leaves, fibre weight and stick weight. Observations and records on disease and pest incidence, quick growing,smoothness and earliness were done.

Achievement/Findings:

In this experiment, it was observed that at JAES, Manikganj only the kenaf line KE-3 showed better performance (25.60g/plant) than the recommended variety HC-95 (19.50 g/plant). At Faridpur, the breeding lines KE-1 (46 g/plant), KE-2 (39 g/plant) and PS-1 (40 g/plant) showed better performance than the recommended variety HC-95 (38 g/plant) in respect of plant height, base diameter, fresh weight, sundry weight and fibre weight which are statistically significant.
