Abstract/ Executive Summary:

The most promising lines selected from previous years yield trial were grown at Pulses Research Centre, Ishurdi, Pabna during Kharif II 2016 which laid out in RCB design with 3 replications with a view to select promising genotypes. Days to maturity, plant height, disease score and yield were showed significant differences among the genotypes and rest of the traits showed non- significant among the genotypes. The entry BG-2 flowered and matured earlier than the entry BG-3 followed by BG-7 and BG- 4 matured late. Among the entries highest yield was obtained from BG- 4 followed by BG-7 and BG-2.

Keywords: Balckgram, Disease, Blackgram genotypes, SAARC Country

Location: Pulses Research Centre, Ishurdi, Pabna, Bangladesh

Start Date: 00-00-2016

End Date: 00-00-2016

Program Area: Variety and Species

Commodity: Black gram

Objectives:

To develop such a bridge between each of the member countries, such an experiment on blackgram with genotypes collected from different SAARC countries through SAARC Agricultural Information Centre (SAIC), Bangladesh

Methodology:

Four lines were grown along with check variety BARI Mash-3 in Kharif-II season of 2016 at Pulses Research Centre, Ishurdi, Pabna. The experiment was laid out in a RCB design with three replications and seeds were sown in the field on 01 September 2016. Each entry was sown in 8 rows 4 m long plot with a spacing of 40 cm between rows. Spacing between two plots were 50 cm. Irrigation was given to ensure seed germination. Mulching was done and soil crusts were broken. General cultural practices were followed to maintain the experiment except that no insecticide and fungicide was sprayed to encourage whitefly population for spread of the disease. Each of the entries were investigated from seedling to harvest and compared with check. From each plot 10 plants were selected randomly to record data. Yield data was recorded from the whole plot and converted into kg/ha. Data were recorded also on days to flowering (DF), days to maturity (DM), plant height (PH), pod/plant (PPP), seeds/pod (SPP), 100 seed weight, YMV and yield (Y) (kg/ha). Data were analyzed following STAR computer program. Yield and yield contributing characters are presented. Disease severity was recorded at weekly interval using 0-5 arbitrary scale (Bashir, 2005) which is described.

Achievement/Findings:

Considering above characteristics, BG-4 followed by BG-7 and BG-2 was found better in respect of yield and related attributes. These entries will be evaluated over locations to assess their performance, stability and reaction against disease.
