Abstract/ Executive Summary:

Twenty-two morpho-agronomic traits of 42 jute genotypes, including 4 varieties with 38 accessions of C. capsularis were evaluated to assess the extent and patterns of variability and their relationships. Seed traits exhibited a wider range of variation than fiber traits. Qualitative traits were also the most informative. Considerable ranges of variability were observed in stem colour, petiole colour, stipule colour, plant technical height, base diameter, dry fibre weight and dry stick weight. Based on major yield contributing characters’ accessions 628, 633, 635 and 646 performed better in most of the cases than the control variety CVL-1, CVE-3, BJC-7370 and BJC-83.

Location: Bangladesh Agricultural University, Mymensingh 2202, Bangladesh

Start Date: 00-00-2016

End Date: 00-00-2016

Program Area: Variety and Species

Commodity: Jute

Objectives:

To assess the extent and patterns of variability and their relationship of Deshi Jute

Methodology:

The experiment was conducted by sowing seeds on 7 April, 2016. Thirty-eight entries along with the check varieties CVE-3, CVL-1, BJC-7370 and BJC-83 were taken to this study. Each accession was sown in 5 rows of 3 m length; spacing was 30 cm between rows, 5-6 cm between plants and 1 m between plots. Standard cultural and inter-cultural practices were followed. Pigmentation data on stem colour, leaf colour, vein colour, petiole colour, stipule colour, bud colour, and fruit colour were collected at 60 days after sowing and pre-bud stage. Plants were harvested at 120 days after sowing and post-harvest data were collected as per Corchorus Descriptor. Data were analyzed following standard statistical procedures.

Achievement/Findings:

The experiment demonstrates that the studied genotypes were highly variable for all of the morpho- agronomic traits and the accessions of C. capsularis 628, 633, 635 and 646 performed better in respect of major yield contributing traits than the controls CVE-3, CVL-1, BJC-7370 and BJC-83. Hence it can be concluded that these promising accessions may be used in a hybridization programme, to enhance fibre yield of deshi jute.
