Abstract/ Executive Summary:

The experiment was designed to monitor the viability of jute, kenaf and mesta germ plasm for storage and maintenance during November-December, 2004. Gene Bank of BJRI has been started conservation of only seeds of jute, kenaf, mesta and allied fibre since 1982 with installation of ex-situ conservation facilities for medium-term (10-15 years,+4C) and long-term (30-50 years, -20C) storage. As the time passes, the viability of the accessions decreases and in general when it comes down to 80% germination the particular accession needs regeneration. For monitoring the viability, 5 kenaf accessions stored at +4C and –20C during 1983-1994 of having > 80% initial germination were allowed to germinate in petsidish. Seeds of acc. No. 1568 stored at + 4oC in 1984 had totally lost their germ inability and hence this accession should be replaced. Similarly those accessions showed ?80% viability need to be regenerated for seed multiplication.

Keywords: Monitoring, viability, germination

Location: Gene Bank Department, BJRI, Dhaka

Start Date: 00-00-2004

End Date: 00-00-2004

Program Area: Variety and Species

Commodity: Mesta, kenaf, Jute

Objectives:

To monitor the viability of jute, kenaf and mesta germ plasm for storage and maintenance

Methodology:

100 seeds of each accession were studied for germination. The seeds were allowed to germinate in 4 replicated forms with 25 seeds in each petridish. The viability test was recorded for three days from the date of germination test. The materials under study were accessions 1566, 1567, 1568, 1569 and 1570, stored at +4 ⁰C and –20⁰C during 1983-1994 of having > 80% initial germination. Germination percent was recorded as per recommended ISTA rules.

Achievement/Findings:

For monitoring the viability, 5 kenaf accessions stored at +4C and –20C during 1983-1994 of having > 80% initial germination were allowed to germinate in petsidish. Seeds of acc.
