Abstract/ Executive Summary:

Four lentil genotypes were collected from ICARDA (International Center for Agricultural Research in Dry Areas), Aleppo, Syria and evaluated under five locations in Bangladesh viz. Pulses Research Center, Ishurdi; Regional Agricultural Research Station, Jessore; Regional Agricultural Research Station, Jamalpur; Regional Pulse Research Station, Madaripur and Bangladesh Agricultural Research Institute, Gazipur during the year 2013-14. The lines are BLX 07003-6, BLX 07004-7, BLX 07004-2, BLX 07004-12 and BARI masur-7 as check were included in the experiment. The experiment was laid out in a completely randomized block design with three replications. Significant variation was observed for days to flowering, days to maturity, pods per plant, 1000 seed weight and yield in kg hectare^-1. 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.The lowest days to maturity was recorded in BLX 07004-7.The entry BLX 07003-6 showed highest plant height followed by BLX 07004-2. The lowest disease score of stemphylium blight was recorded in BLX 07004-12 and BARImasur-7 followed by BLX 07004-2 and BLX 07003-6. The highest disease score of stemphylium blight was recorded in BLX 07004-7.The entry BLX 07004-2 showed the highest yield followed by BLX 07004-12.

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

The present experiment was undertaken to evaluate growth, maturity, and yield performance of the collected lentil genotypes with a view to develop a new variety(s) having desirable traits.

Methodology:

The experiment was conducted at the research field of five locations viz.1. Pulses Research Center, Ishurdi 2. Regional Agricultural Research Station, Jessore 3. Regional Agricultural Research Station, Jamalpur, 4. Regional Pulse Research Station, Madaripur and 5. Bangladesh Agricultural Research Institute, Gazipur during the period of 2013-14. The experimental materials comprised of four advanced lentil genotypes namely BLX 07003-6, BLX 07004-7, BLX 07004-2, and BLX 07004-12 including BARI masur-7 as check. All the genotypes were obtained from ICARDA. The experiment was laid out in the Randomized Complete Block Design (RCBD) with three replications. Each entry was sown in unit plot of 4 m X 2.4 m long with a spacing of 40 cm between rows. Spacing between two plots were 40 cm. The experimental field was prepared by repeated ploughing followed by laddering. After ploughing and laddering all the stubble and uprooted weeds were removed from the field. Before final land preparation, NPKS was applied @ 20-40-20-10 kg ha^–1, respectively. Seeds were sown in the rows carefully by hands at 3 cm depth and then covered by soils. Seeds were sown on 10 November to 16 November. Post sowing irrigation was given to ensure seed germination. 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. Data on yield contributing characters were taken from the 10 randomly selected plants from the middle rows of each plot. Data on different parameters such as plant height, days to flowering, days to maturity, pods plant^–1, 100 seed weight and seed yield were recorded from each plot. The collected data from the experiment were analyzed by using statistical package programme MSTAT-C to illustrate the statistical significance of the experimental results. The means differences were compared by using Least Significant Difference (LSD) test at 5% level of significance. The GGE biplots is a component of genetics variance for all the characters which was done according to yield.

Achievement/Findings:

The aforesaid results indicated the lines collected from ICARDA showed good variation in days to flowering, days to maturity, pods per plant, 100 seed weight and yield and also disease infection. The evaluation of growth parameters, yield attributes and final yield indicated that lines BLX 07004-2 and BLX 07004-12 can be recommended for new improved variety development program.
