Abstract/ Executive Summary:

The experiment was designed to monitor the viability of jute, kenaf and mesta germplasm for storage and maintenance during July-December, 2005. 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,+40C) and long-term (30-50 years, -200C) 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. With this view in mind,10 mesta and 8 kenaf accessions stored at +40C and –200C during 1983-1996 having > 80% initial germination were allowed to germinate in petsidish. Seeds of acc. No. 1701 and 1702 stored at + 4oC in 1987 and 1988 respectively had totally lost their germinability and hence these accessions should be replaced. Similarly the seed of kenaf accession no. 1572 stored at -200C in 1983 had totally lost their germinability and hence these accessions should be replaced. Similar scenario in the accession no. 1575 and 1577 stored at + 4oC in 1983 and 1985 respectively. Therefore, the seed packets must be replaced. Accessions showed > 80% viability both for mesta and kenaf need to be regenerated for seed multiplication.

Keywords: Monitoring, Viability, Germination

Location: Gene Bank Department, Dhaka

Start Date: 15-07-2005

End Date: 31-12-2005

Program Area: Variety and Species

Commodity: Mesta, kenaf, Jute

Objectives:

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

Methodology:

100 seeds of each accession were studied for germination. The seeds were allowed to germinate in 4 replicated form with 25 seeds in each petridish. The viability test were recorded for three days from the date of germination test. Germination percent was recorded as per recommended ISTA rules.

Achievement/Findings:

For monitoring the viability 10 mesta and 8 kenaf accessions stored at +4 C and –20 C during 1983-1996 having > 80% initial germination were allowed to germinate in petsidish. Seeds of acc. No. 1701 and 1702 stored at + 4oC in 1987 and 1988 respectively had totally lost their germ inability and hence these accessions should be replaced. Similarly the seed of kenaf accession no. 1572 stored at -200C in 1983 had totally lost their germ inability and hence these accessions should be replaced. Similar scenario in the accession no. 1575 and 1577 stored at + 4oC in 1983 and 1985 respectively. Therefore, the seed packets must be replaced. Accessions showed > 80% viability both for mesta and kenaf need to be regenerated for seed multiplication.
