Abstract/ Executive Summary:

Significant variation was observed for days to flower, days to maturity, pods per plant, 100 seed weight and yield in kg per hectare. The lowest days to matyrity was recorded in BLX 07004-7. Large seed size was recorded in BLX 07004-12. The entry BLX 07004-2 showed the highest yield followed by BLX 07004-12.

Keywords: Preliminary, Yield trial, Lentil

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

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Lentil

Objectives:

To evaluate the Preliminary Yield Trial in a single or multiple location(s) to asses the performance

Methodology:

The experiment consisted of five entries including BARI Lentil-7 as check. It was conducted at five locations, Pulses Research Center, Ishurdi, RARS Jessore, RARS Jamalpur, RPRS Madaripur and Gazipur during Rabi 2013-14 (16 to 23 November) in a RCB design with 3 replications. Each entry was sown in 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:

There was a significant variation among the genotypes regarding days to flower, days to maturity, pod per plant, 100 seed weight and yield in kg per hectare. The lowest days to maturity was recorded in BLX 07004-7. Among the test entries, BLX 07004-2 showed the highest numbers of pods/plant followed by BLX 07004-12 while the largest seed size was recorded in BLX 07004-12. GGE biplot analysis was done to find out stable genotypes among locations.GGE biplot is exploited for graphical display of G×E pattern of yield trial data with several advantages. The yield of each cultivar in a tested environment is a result of genotypic main effect (G), environmental main effect (E) and genotype × environment (GE) interaction (Yan and Kang, 2002). In this experiment, the first two PCs of the GGE model explained 97% of variation in G+GE. Five genotypes represent a polygon and the genotypes corner of the polygon most responsive genotypes . The genotypes BLX07004-2 showed most interaction with environment followed by BLX07004-12. All the entries distributed into three sectors. Among the tested location, Jessore, Ishurdi and Madaripur had larger environmental vectors indicating high discriminating ability. GGE biplot of yield showed entry BLX 07004-2 and BLX 07004-12 appeared to be widely adaptive compared to the rest. The out yielded entries were also found resistant reaction to stemphylium blight.
