Abstract/ Executive Summary:

The experiment was conducted at Pulses Research Centre, Ishwardi, Pabna, Regional Agricultural Research Station Jessore and Jamalpur, Regianal Pulse Research Station, Madaripur, Onfarm Research Division, Barind, Rajshahi and Pulses Research Sub Centre, Gazipur during kharif-II, 2015 to find out desirable lines of Blackgram. Six Blackgram lines BBLX-07002-1, BBLX-07002-5, BBLX-06002-10, BBLX-02005-1 and 86337 were used in the experiment where BARI Mash-3 was used as a check variety. The experiment was laid out in a RCB design with three replications seeds were sown in the field on 10 to 20 August 2015. Each entry was sown in 6 rows 4 m long plot with a spacing of 40 cm between rows. Spacing between two plots was 40 cm. The genotypes 86337 gave highest average yield (1206 kg ha-1) among the genotypes followed by BBLX-06002-10(1089 kg ha-1) and BBLX-07002-5 (1076 kg ha-1). It also produced highest seed yield in Joydebpur (1334 kg ha-1) across the locations. Out of six locations 86337 genotypes produced a good yield (1206 kg ha-1) on the other hand, the lowest average yield was obtained from the genotypes BBLX-07002-1 (1043 kg ha-1). The lines 86337, BBLX-06002-10, BBLX-07002-5 and 86337 gave greater seed yield which would be used for crop improvement breeding programs.

Program Area: Variety and Species

Commodity: Black gram

Objectives:

The present study was taken with eight promising lines to investigate desirable lines of blackgram in Kharif-II season under four different pulse growing locations of Bangladesh.

Methodology:

The experiment was conducted at Pulses Research Centre, Ishwardi, Pabna, Regional Agricultural Research Station Jessore and Jamalpur, Regional Pulse Research Station, Madaripur, On Farm Research Division, Barind, Rajshahi and Pulses Research Sub Centre, Gazipur during Kharif-II, 2015 to find out desirable lines of Blackgram. The experiment was laid out in a randomized complete block design with three replications. Seeds were sown in the field on 10 to 20 August 2015. Each entry was sown in 6 rows 4 m long plot with a spacing of 40 cm between rows. Spacing between two plots were 40 cm. 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 check. From each plot 10 plants were selected randomly to compute data. Yield data was recorded from the whole plot and converted into kg ha-1. Data was recorded on days to flowering, days to maturity, plant height, pod plant -1, 100- seed weight and yield (kg ha-1). Data on MYMV disease were taken on a 0-8 scoring scale (Malik, 1991) where 0 = no infection, 1 = 0-6% plant part infected (I), 2 = 6-10% plant part infected (HR), 3 = 11-20% plant part infected (R), 4 = 21-30% plant part infected (MR), 5 = 31-40% plant part infected (T), 6 = 41-50% plant part infected (MT), 7 = 51-80% plant part infected (S), 8 = 81-100% plant part infected (HS). The data were analyzed by computer using MSTAT-C Package while the mean separation was done by Duncan’s Multiple Range Test (Steel & Torrie, 1960).

Achievement/Findings:

The genotype 86337 and BBLX-06002-10 showed the highest number of pods per plant (28) and the genotype BBLX-02005-1 showed the lowest number of pods per plant (24). In terms of disease, all the entries showed moderate tolerance to BYMV. The genotypes 86337 gave highest average yield (1206 kg ha-1) among the genotypes followed by BBLX-06002-10 (1089 kg ha-1) and BBLX-07002-5 (1076 kg ha-1). It also produced highest seed yield in Joydebpur (1334 kg ha-1) across the locations. Out of six locations 86337 genotypes produced a greater yield (1206 kg ha-1) on the other hand, the lowest average yield was obtained from the genotypes BBLX-07002-1 (1043 kg ha-1). From this evaluation it may be suggested that the test entries BBLX-06002-10, BBLX-07002-5 and 86337 would be used for crop improvement breeding programs.
