Abstract/ Executive Summary:

The experiment was designed to monitor the viability of tossa jute germplasm for storage and maintenance during November-December, 2002. 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,+4 C) and long-term (30-50 years, -20 C) 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 a view to study the viability percent of the seeds of the Gene Bank, forty eight accessions tossa jute were studied which have been stored at +4 C and -20 C during the period 1985 to 1990 were allowed to germinate in petridishes. It was observed that each accession have seeds of several years in the Gene Bank and their germination percent was varied from 43-100%. The accessions less than 80% germination need to be regenerated for seed production. It was also observed that the accession 1027, 1039, 1040, 1042, 1051, 1053, 1062, 1069 and 1070 were showed >80% germination for all the tested years compared with all other accessions. Therefore, the accessions with < 80% germination should be regenerated for seed multiplication.

Keywords: Monitoring, Viability, Germplasm

Location: Gene Bank Department,Dhaka

Start Date: 01-11-2002

End Date: 31-12-2002

Program Area: Variety and Species

Commodity: Jute

Objectives:

To monitor the seed viability of tossa jute germplasm for storage and maintenance

Methodology:

100 seeds of each accession were studied for germination during November-December, 2002. 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. Forty eight tossa jute germ plasm were studied for this experiment which stored at +4 ⁰C and –20⁰C during 1985-1990 of having > 80% initial germination. Germination percent was recorded as per recommended ISTA rules.

Achievement/Findings:

It was observed that each accession have seeds of several years in the Gene Bank and their germination percent was varied from 43-100%. The accessions less than 80% germination need to be regenerated for seed production. It was also observed that the accession 1027, 1039, 1040, 1042, 1051, 1053, 1062, 1069 and 1070 were showed >80% germination for all the tested years compared with all other accessions. Therefore, the accessions with < 80% germination should be regenerated for seed multiplication.
