Selection of Salt Tolerant Jute Cultivars and Their Stability in Coastal Region of Bangladesh.

Abstract/ Executive Summary:

Genotype-location interaction as well as stability for yield and yield contributing characters of 10 cross- combinations was assessed at three different locations through regression and deviation from regression analysis, variances for genotypes (combinations), locations and GxE interactions were significant for all the characters. Considering mean value, phenotypic index and stability parameters (bi and s2di) for dry fibre weight/plant, cross combinations G₁ (C-3473XD-154 and G₂ (C-12221XD-154), are the average responsive. Hence these genotypes are suitable for all environments. On the other hand combinations G₃ (C-12033XD-154), and G₄ (C-2593XD-154) showed highly responsive, i.e. increasing sensitivity to environmental changes and also showed higher mean value in env-2 than other environments. Therefore these G₃ (C-12033XD-154), and G₄ (C-2593XD-154) combinations are suitable G3 (C-12033XD-154), and G₄ (C-2593XD-154) for favorable environment i.e. highly salt affected soil areas in Bangladesh.

Keywords: Salt tolerant, jute, and cultivar

Location: Pakhimara, Patuakhali and Banarpota, Satkhira.

Start Date: 15-03-2012

End Date: 31-07-2012

Program Area: Variety and Species

Commodity: Jute

Objectives:

To evaluate the performance selected genotypes base on fibre yield and yield contributing characters. To select the salt tolerant and stable genotypes.

Methodology:

Fifty (50) accessions/genotypes of diverse geographical origin of white jute including 2 check varieties of diverse geographical origin will be collected from Gene bank of BJRI and Capsularis Department of Breeding Division. The experiment was carried out in field condition following standard procedure. Seeds of each genotypes was grown in individual plot. Each plot size was 3.00 x 2.10 sqm. Seeds were grown in a Randomized Complete Block Design with three replications. Data were recorded on population at germination and harvesting time, plant height, base diameter, green weight with leaves, green weight without leaves, dry fibre weight, dry stick weight, number of fruits/plant, seed weight/plant.
