Improvement of Fibre Yield and Associated Traits in White Jute 2004.

Dr.Rahima Khatun
Principal Scientific Officer
Capsularis Department Breeding Division Bangladesh Jute Research Institute Manikmia Avenue, Dhaka-1207

Abstract/ Executive Summary:

Under this experiment, a total of one hundred and sixteen selected plants of F5 generation were evaluated under field condition in 2004. Seeds were sown in a randomized complete block design (RCBD) with two replications. From these, F5 generation twenty promising lines of different cross combination viz. CVL-1 x 1831, CVL-1 x A-38, 1515 x CVL-1, 1831 x 1515, 1831 x 1832, 1831 x 2146, 1831 x 4087, 1831 x A-38, 1831 x CC-45, 1833 x A-38, 2146 x CVL-1, 2146 x 4087, 4087 x CVL-1, 4087 x 1831, 4087 x A-38, A-38 x 1832, A-38 x 1833, A-38 x 4087, CC-45 x 1832 and CC-45 x A-38 were remarked on the basis of plant height, base diameter, leaf shape pigmentation pattern and seed coat colour. Beside this 50 best plants were selected from different cross combination in respect of desired traits.

Keywords: Improvement, fibre yield, associated traits and white jute.

Location: Central Jute Agricultural Experiment Station (JAES), Manikganj

Start Date: 25-03-2004

End Date: 31-12-2004

Program Area: Variety and Species

Commodity: Jute

Objectives:

To select superior hybrids with desired traits.

Methodology:

A total of one hundred and sixteen selected plants of F5 generation were evaluated under field condition in 2004.Seeds were sown in a randomized complete block design (RCBD) with two replications having unit plot size of 3.6m long row with a row to row distance of 30cm. The space between adjacent plants within rows was 5-6cm. Data were recorded on date of sowing, germination, first and final thining, first and average flowering, harvest, steeping and extraction. Observations on pest and diseases and selection of tolerant lines.plant height, base diameter, green weight, fibre weight, stick weight, number of nodes, number of brances, number of fruits per plant, seed yield/plant and 1000 seeds weight were recorded at harvest.Standard agronomic practices were followed for uniform growth and development.
