Abstract/ Executive Summary:

Millions of hectares of rice lands are technically suited for rice production but are left uncultivated or are grown with very low yields because of soil salinity and problem soils. About 53% of the coastal areas are affected by salinity due to inundations from the sea, and intrusion of sea water through rivers, estuaries, etc. The study was conducted in the saline areas of Bangladesh to find out the best variety/mutant line and other performance in the coastal areas of this country. To assess the performance of the variety PRA, preference analysis and correlation analysis were done. It was observed that among the rice variety/lines, Binadhan-8 showed the utmost performance i.e., grain yield of the variety was the highest in all the studied areas. So, this variety could be suggested for cultivation in the saline areas of Bangladesh.

Keywords: Participatory variety selecton, Boro rice, Coastal areas, Preference analysis

Location: Labanchara upazilla of Khulna, Kaligang and Shamnagar upazillas of Satkhira district

Start Date: 00-00-2011

End Date: 00-00-2011

Program Area: Variety and Species

Commodity: Rice

Objectives:

To find out the best variety/mutant line and other performance in the coastal areas of this country.

Methodology:

The study was conducted based on primary data at Labanchara upazilla of Khulna, Kaligang and Shamnagar upazillas of Satkhira district during the T. aman season of 2011. In total 90 farmers were selected for the study taking 30 farmers in each area. In the sampled areas, data were collected through pre-designed interview schedule. In Labanchara, nine advanced rice lines with one salt tolerant check variety (Binadhan-8), in Kaligang and Shamnagar one advanced rice line with one salt tolerant check variety (Binadhan-8) were considered for the study. The design of the experiment was Randomized Completely Block (RCB) design with three replications. Farmer’s preferences were considered on the characters of good yield, salt tolerant, long panicle, more number of tillers in a hill, attractive color of grain, fine grain, etc. In the study, the preference analysis and the correlation analysis were done for analyzing the collected data.

Achievement/Findings:

From the finding, it could be concluded that Binadhan-8 exhibited the utmost performance in all studied areas. Grain yields of Binadhan-8 were 5.00, 4.53, 2.08 t ha^-1 at Shyamnagar, Labanchara and Kaligang upazilla, respectively which was the highest production over the other rice lines. Therefore, its cultivation could be expanded in the saline areas of Bangladesh.
