Abstract/ Executive Summary:

This experiment was carried out in concrete tanks in the glass house premises of BJRI. Forty four C. olitorius accessions along with three controls var. O-4, O-9897 and OM-1 were tested for water logging tolerance. The seeds of each accession and variety were sown (D/S: 04/05/2000) in 30 cm earthen pots with 3 replications and each pot contained 5 plants after final thinning. From 3 sets, two sets of plants were immersed in water to one-third of plant height at the age of 60 days from the date of sowing. The water logging condition was maintained for 30 days. After 30 days plants were taken out from water and visual score (0-5) of adventitious root and number f rotted stems were recorded. Fifteen days after removal from water, mortality rate (%) was recorded. During deeping period the water surface of the tank was fully covered by duck weed. It was observed after 15 days from the date of deeping that there was no adventitious roots in any plant in any accessions and the stem started to rot. It was unusual, we rapidly removed the duck weed but no adventitious roots were formed and no plants were survived. This may happened due to shortage of biological oxygen in the water.

Keywords: Screening, Olitorius, Germplasm, Water logging, Tolerance, Pot

Location: In the glass house premises of BJRI.

Start Date: 04-05-2000

End Date: 10-12-2000

Program Area: Variety and Species

Commodity: Jute

Objectives:

To identify the water logged c. olitorius germ plasm

Methodology:

This experiment was conducted in concrete tanks in the gass house premises of BJRI. Forty four C. olitorius accessions along with three controls var. O-4, O-9897 and OM-1 were tested for water logging tolerance. The seeds of each accession and variety were sown (D/S: 04/05/2000) in 30 cm earthen pots with 3 replications and each pot contained 5 plants after final thinning. From 3 sets, two sets of plants were immersed in water to one-third of plant height at the age of 60 days from the date of sowing. The water logging condition was maintained for 30 days. After 30 days plants were taken out from water and visual score (0-5) of adventitious root and number f rotted stems were recorded.

Achievement/Findings:

Fifteen days after removal from water, mortality rate (%) was recorded. During deeping period the water surface of the tank was fully covered by duck weed. It was observed after 15 days from the date of deeping that there was no adventitious roots in any plant in any accessions and the stem started to rot. It was unusual, we rapidly removed the duck weed but no adventitious roots were formed and no plants were survived. This may happened due to shortage of biological oxygen in the water.
