Abstract/ Executive Summary:

Eight families selected from last season’s F₅treated as lines and eight exotic lentil lines were grown with check variety BARI Masur-6, BARI Masur-7, BARI Masur-8 and one local check Bagura local in rabi season of 2017-18 at Pulses research centre, Ishurdi, Pabna followed RCBD design with two replication. Finally Eleven genotypes viz: BLX-12011-6, RL-12-181, Maitree, BLX-12005-4, KLS-218, RL-12-178, BLX-12009-6, BLX-12004-5, RL-12-171, L 4717, and Bagura local were preliminarily selected for PYT in the next season.

Program Area: Variety and Species

Commodity: Lentil

Objectives:

The accessions are evaluated in the replicated observation trial comparing with the standard commercial varieties using as checks for evaluation their yield performance and visual grain color considering our farmers

Methodology:

Eight families selected from last season F₅s generation, and eight exotic lentil lines were grown with three commercial varieties (BARI Masur-6, BARI Masur-7 and BARI Masur-8) and one local variety (Bagura Local) as check during rabi, 2017-18 at Pulses Research Centre, Ishurdi, Pabna. The experiment was laid out in a RCB design with two replications and spacing of 38 cm between rows. Each entry was sown in 2 rows of 4m long plot. Seeds were sown in the rows carefully by hands at 3 cm depth and then covered by soil. Post sowing irrigation was given to ensure seed germination. Mulching was done and soil crusts were broken. Each of the entries were investigated from seedling to harvest and compared with checks. At maturity stage genotypes were selected on the basis of earliness, disease reaction and podding higher yield. Yield data was recorded from the whole plot and converted into kg/ha. The statistical analysis was done using PLABSTAT computer software.Yield and yield contributing characters

Achievement/Findings:

Statistically significant differences were observed only days to flower, days to maturity and plant height only among the genotypes except yield and other yield contribution characters (Table-1.8). Among the twenty check variety Bagura local and genotype RL-12-178 flowered and matured earlier followed by BLX 12002-3. The maximum final plant stand 96 was recorded in case of genotype RL-12-181and the minimum was 42 in case of genotype BLX-12002-3 yield 1575 kg ha^-1which minimum compare to of all check varieties. RL-12-181 produced the second highest yield (2126.65 kg ha^-1) with the maximum plant height (50.6 cm) and the genotype BLX-12002-2 was dwarf (37.20 cm) with the third lowest yield (1485.20kg ha^-1) among the evaluated genotypes. The maximum pods 93 was recorded in case of Bagura local check variety with 1610 kg ha^-1yield and the minimum pods 52 was in genotype L 4717 with yield 1610 kg ha^-1 . BARI Masur-8 was recorded as bold seeded (100 seeds weight 2.45 g) among the all genotypes. The maximum yield was recorded in case of genotype BLX-12011-6 which was followed by genotypes RL-12-181 and Maitree yielded 2126.65 kg ha^-1 and 2060.86 kg ha^-1 respectively. Comparing with all check varieties BLX-12011-6, RL-12-181 and Maitree gave the maximum yield 2189.15 kg ha^-1, 2126.65 kg ha^-1, and 2060.86 kg ha^-1respectively. Whereas the genotypes BLX-12005-4 (1787.83 kg ha^-1), KLS-218 (1777.96 kg ha^-1), RL-12-178 (1741.78 kg ha^-1), BLX-12009-6 (1728.62 kg ha^-1), BLX-12004-5 (1646.38 kg ha^-1), RL-12-171 (1623.35 kg ha^-1), L 4717 (1610.20 kg ha^-1) and Bagura local (1610.20 kg ha^-1) performed higher yield compare to check variety BARI Masur-6 (1582.23 kg ha^-1) but lower to BARI Masur-7 and BARI Masur-8. The genotypes BLX-12011-6, RL-12-181, Maitree,BLX-12005-4, KLS-218, RL-12-178, BLX-12009-6, BLX-12004-5, RL-12-171, L4717, and Bagura local were selected considering their yield performance with the using all checks varieties.

Considering the yield, yield contributing traits and visual observation of seeds 11 entries viz.BLX-12011-6, RL-12-181, Maitree, BLX-12005-4, KLS-218, RL-12-178, BLX-12009-6, BLX-12004-5, RL-12-171, L 4717, and Bagura local were selected to evaluate as PYT in next rabi season.
