Abstract/ Executive Summary:

To evaluate the performance and to asses their suitability, preliminary yield trial was conducted during Rabi 2013-14. The trial consisted of five entries including BARI Lentil-7 as check. It was conducted at five locations namely, Pulses Research Center, Ishurdi, RARS Jessore, RARS Jamalpur, RPRS Madaripur and Gazipur in RCBD with 3 replications. From the result, significant variation was observed for days to flowering, days to maturity, pods per plant, 100 seed weight and yield in kg/hectare. The lowest maturity days of 10 was recorded in BLX 07004-7. Large seed size was recorded in BLX 07004-12. The entry BLX 07004-2 found to be the highest yielder followed by BLX 07004-12.

Keywords: Pulse, Lentil, Lentil-7, Grain yield

Location: Pulses Research Center, Ishurdi; RARS Jessore; RARS Jamalpur; RPRS Madaripur and Gazipur, Bangladesh

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Lentil

Objectives:

To conduct preliminary yield trial in a single or multiple location(s)
To evaluate the performance of Lentil

Methodology:

The experiment consisted of five entries including BARI Lentil-7 as check. It was conducted at five locations, viz, Pulses Research Center, Ishurdi; RARS Jessore; RARS Jamalpur; RPRS Madaripur and Gazipur during Rabi season of 2013-14 in RCBD with 3 replications. Each entry was sown in a unit plot of 6 rows X 4 m long with a spacing of 40 cm between rows. Spacing between two plots were 40 cm. Seeds were sown in the rows carefully by hands at 3 cm depth and then 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 were investigated from seedling to harvest and compared with checks. 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. Data were analyzed statistically by using MSTAT-C and R-program.

Achievement/Findings:

The genotypes BLX07004-2 showed most interaction with environment followed by BLX07004-12. Among the tested location, Jessore, Ishurdi and Madaripur had larger environmental vectors indicating high discriminating ability. GGE biplot of yield, showed the entries BLX 07004-2 and BLX 07004-12 to be widely adaptive compared to the rest. The entries were also found resistant in reaction to stemphylium blight.
