Abstract/ Executive Summary:

The experiment was carried out to evaluate the performance of six fieldpea genotypes along with check BARI Motor-1 and BARI Motor-3 for yield and yield-related traits in five locations during Rabi 2018-19. Considering mean data for both days to flower and maturity BFP 11016 was found earlier. BARI Motor-3 followed by Sekim local produced the highest numbers of pods/plant. Apart from these, maximum seed weight was observed in Sekim local. In case of yield performance over locations, Jhikorgacha local performed the best among the genotypes. Considering biplot analysis and yield data, the genotypes viz. BFP-11016, Jhikargacha local and BARI motor-3 showed stable performance across the locations.

Keywords: Pulses, Lentil, Grain yield, Fieldpea, BARI Motor-1, BARI Motor-3

Location: Ishurdi, Gazipur, Jashore, Madaripur and Jamalpur, Bangladesh

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Chickpea

Objectives:

To evaluate them in the regional yield trial (RYT) in multiple location(s) to assess their stability performance.

Methodology:

The experiment consisted of six entries including BARI Motor-1 and BARI Motor-3 as a check. The experiment was laid out in an RCB design with three replications at five different locations (Ishurdi, Gazipur, Jashore, Madaripur and Jamalpur. Each entry was sown in-unit plot of 6 rows × 4 m long with a spacing of 50 cm between rows and plant to plant 10 cm. The spacing between the two plots was 50 cm. Seeds were sown in the rows carefully by hands at 3 cm depth and covered by soils. Post sowing irrigation was given to ensure seed germination. Mulching was done and crusts were broken. Weeding was done to keep the plots free from weeds. Each of the entries was observed seedling to harvest and compared with check. Grain yield was calculated from the whole plot. Yield contributing characters were taken from the 10 randomly selected plants from the middle rows of each plot. At maturity stage, randomly five plants from each plot were selected and harvested separately for recording the yield contributing traits like plant height, pods plant^-1, 100 seeds weight, seeds pods^-1 etc. Yield data was recorded from the whole plot and converted into kg ha^-1. The statistical analysis was done using GENSTAT computer software. Yield stability for the different five locations was analyzed using the PB Tools computer software. Yield and yield contributing characters are presented

Achievement/Findings:

Significant variation was observed among the genotypes regarding days to flower, days to maturity, pods per plant, 100 seed weight and yield in kg ha^-1. In case of flowering and maturity among the five locations, genotypes performed a bit earlier at Jamalpur followed by Madaripur. Among the genotypes,BFP 11016 was flowered earlier and also showed earlier maturity followed by Jhikorgacha local. Among the test entries, BFP 11016 was most dwarf one. Comparatively shorter plants were observed in Gazipur and taller in Ishurdi. The entries, BARI Motor-3 followed by Sekim local produced highest numbers of pods/plant. The number of pods varied from location to location. It was comparatively maximum at Ishurdi whereas in Madaripur and Gazipur it was comparatively minimum. Apart from these, maximum100 seed weight was observed in Sekim local from the mean values of five locations. In case of yield performance over locations, Jhikargacha local performed best (1550 kg/ha) followed by BARI Motor-3 among the genotypes. Compared to five locations, almost all the genotypes produced significantly higher yield in Ishurdi (Range: 1145-2585 kg/ha) whereas in Gazipur it was minimum with a range of 400-1119 kg/ha. Considering different desirable characters and stability parameters, two entries viz. Jhikorgacha local and BFP-11016 were selected to evaluate during next season at PVS trial.
