Abstract/ Executive Summary:

An experiment was conducted in the farmer's field at four locations viz, Joydepur, Barisal, Jamalpur and Jessore during Rabi 2013-14 to find out desirable lines through farmer participation. Different genotypes of lentil (Masur) showed significant variation among the parameters except days to maturity at Jessore and plant height at Jamalpur location. The genotype BLX-05008-15 was found earlier considering the mean values of four locations. From the mean values of all locations, the highest number of pods was found to be produced by LRIL-22-68 followed by LRIL-9-25. In case of 100 weight, highest seed weight was with LRIL-21-109, followed by BLX-05008-15. The lowest 100 seed weight recorded from BARI Masur 7. The stemphylium blight disease was scored in 0-5 scoring scale. High disease severity was in Jessore location. Lentil genotypes BLX-05002-6, LR-9-25 and BARI Masur 7 were moderately resistant (average score 1.34) and LRIL-21-109, LRIL-22- 205 and LRIL-22-68 were moderately susceptible (average score 2.34). Among the tested location, Jessore, Jamalpur and Barisal had larger environmental vectors indicating high discriminating ability of the genotypes. Polygon showed that the genotypes BLX-05002-6, LRIL-22-68, LRIL-9-25 are suitable for Jessore, Jamalpur and Barisal and BARI Masur 7 for Gazipur location. The genotype BLX-05002-6 gave the highest yield (2243 kg/ha followed by LR-9-25 (1867 kg/ha) and the lowest yield (973 kg/ha) produced by BLX-05008-15 followed by LRIL-21-I09 (1253 kg/ha).

Location: Joydepur, Barisal, Jamalpur and Jessore districts, Bangladesh

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Lentil

Objectives:

To identify the best lentil material with the direct involvement of the farmers

Methodology:

The experiment was conducted in the farmer's field at Joydepur, Barisal, Jamalpur and Jessore region during Rabi 2013-14. The lentil genotypes viz. BLX-05002-6, BLX-05008-15, LRIL-21-109, LRIL-22-205, LRIL-22-68, LR-9-25 and BARI Masur 7 were included in the study. Seeds were sown in unit plot of 2.4m x 4m with row spacing 30 ern. Seeds were sown in the field on 16 to 21 November 2013. The experiment was laid out in RCB design with 3 replications. Weeding, irrigation, and other intercultural operations were done as when necessary. A Stemphylium scoring scale (0-5) with 0 = no infection, 1 = a few scattered leaf infections but no twig blighted, 2 = 5-10% leaflet infection and/or a few scattered (1%) twigs blighted, 3 = 11-20% leaflet infection and/or 1-5% twigs blighted, 4 = 21-50% leaflet infection and/or 6-10% twigs blighted, and 5 = 51 % leaflet infection and/or = 10% twigs blighted was developed by Bakr and Ahmed (1992). Data of different parameters were recorded from 10 plants of each unit plot and analyzed statistically.
