Abstract/ Executive Summary:

The experiment was designed to monitor the viability of twenty deshi jute germplasm for storage and maintenance during November-December, 2004. With a view to study the viability percent of the seeds of Gene Bank, 20 accessions of deshi jute were studied. The viability test was recorded for three days from the date of germination. Percentages of germination were recorded. It was observed that each accession have seeds of several years in the Gene Bank and their germination percent was varied from 42-99%. The accessions less than 80% germination need to be regenerated for seed production. It was also observed that the accession no. 51, 53, 56, 59, 62 and 67 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, germination, viability

Location: Gene Bank Department, Dhaka

Start Date: 01-11-2004

End Date: 31-12-2004

Program Area: Seed Technology

Commodity:

Objectives:

1. To find out present germination status of stored seed samples under different temperature

2. To take proper management for stored seed samples

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. The materials under study were accessions 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69 and 70 stored at +4 ⁰C and –20⁰C during 1984-1999 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 42-99%. The accessions less than 80% germination need to be regenerated for seed production. It was also observed that the accession no. 51, 53, 56, 59, 62 and 67 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.
