Abstract/ Executive Summary:

This experiment was conducted in concrete tanks in the glass house premises of BJRI. Two hundred eighty three plants of which 24 plants from parent O-4 24 from parent incisifolius and 235 plants from F2 were grown in 30 cm earthen pots. The plants were kept in concrete tanks a the age of 60 days and waterlogged condition was created gradually by adding fresh water at 1/3rd height of the plant. The waterlogged condition was maintained up to 30 days, then the plants were taken out from water and visual score (O-5, where 0 indicates no roots and 5 indicates maximum roots). Fifteen days after removal from water, mortality was recorded. In this program that no plants in both the parents were survived but only 8 F2 plants were survived which were. F2 Plant no.9, F2 Plant no.16, F2 Plant no.27, F2 Plant no.51, F2 Plant no.57, F2 Plant no.59, F2 Plant no.130 and F2 Plant no.191.

Location: BJRI Green house and Dhaka University

Start Date: 29-04-2001

End Date: 01-11-2001

Program Area: Variety and Species

Commodity: Jute

Objectives:

To identify molecular marker that is responsible for water logging tolerance.

Methodology:

This experiment was conducted in concrete tanks in the glass house premises of BJRI. Two hundred eighty three plants of which 24 plants from parent O-4 24 from parent incisifolius and 235 plants from F2 were grown in 30 cm earthen pots. The plants were kept in concrete tanks at the age of 60 days and waterlogged condition was created gradually by adding fresh water at 1/3rd height of the plant. The waterlogged condition was maintained up to 30 days, then the plants were taken out from water and visual score (O-5, where 0 indicates no roots and 5 indicates maximum roots) of adventitious roots were recorded. Fifteen days after removal from water, mortality was recorded.
