Abstract/ Executive Summary:

Fibre properties are the most important character for assessing a jute variety/ cultivar/ accession of jute and allied fibre (JAF) crops, which is governed by retting and other post harvest processes. Since many germplasms of Jute, Kenaf and Mesta are preserved in the Gene Bank of BJRI and retting & fibre properties of which are not assessed so far. The experiment was undertaken with a view to generate scientific information regarding the retting and fibre properties taking of six germplasms (C. capsularis var. 3451, 3461, 3476, 3478, 3485 & 3492 and C. olitotius var. 5084, 3396, 3415, 3430, 3432 & 3801) along with check varieties (CVL-1 and O-4) were conducted at Jute Researh Regional station Rangpur, Faridpur, Chandina and JAES, Jagir, Manikgonj in the year of 2005. The plants were grown following uniform and standard cultural practices in all of the stations. Plants of each accession of jute were harvested at just budding stage and retted in identical conditions in all stations. It was observed that out of six accessions of C. capsularis only one accession 3476 was found to be the best fibre yielder in most of the stations. On the other hand, three accessions viz. nos. 3485, 3478 & 3461 were found better in terms of fibre quality. In case of C. olitorius accession 3801 was found to be the best fibre yielder. On the other hand, three accessions viz. nos. 3438, 3415 & 3432 in terms of fibre quality in most of the accessions.

Keywords: Screening, Germplasms , Retting, Fibre properties

Location: Jute Research Regional station Rangpur, Faridpur, Chandina and JAES, Jagir, Manikgonj.

Start Date: 01-03-2005

End Date: 30-12-2005

Program Area: Variety and Species

Commodity: Jute

Objectives:

To assess the retting and fibre properties of the new accessions (C. capsularis and C. olitotius) germplasms.

Methodology:

Six accessions (for C. capsularis var. 3451, 3461, 3476, 3478, 3485, and 3492 and C. olitotius var. 5084, 3396, 3415, 3430, 3432 and 3801) each of jute were collected from Genebank, BJRI along with present check varieties (CVL-1 & O-4) were grown under identical conditions and agricultural practices in the field. Plants of each accession along with chech varieties were harvested at just budding stage and were retted in identical conditions. End point of retting was determined critically. Fibres were extracted, washed, dried and assessed in respect of color and percent cuttings and overall grading properties.

Achievement/Findings:

From the experimental result, it was observed that out of six accessions of C. capsularis only one accession 3476 was found to be the best fiber yielder in most of the stations. On the other hand, three accessions viz. nos. 3485, 3478 & 3461 were found better in terms of fibre quality. In case of C. olitorius accession 3801 was found to be the best fiber yielder. On the other hand, three accessions viz. nos. 3438, 3415 & 3432 in terms of fiber quality in most of the accessions.
