Abstract/ Executive Summary:

The experiment was carried out at RPRS, Madaripur, PRC, Ishurdi and RARS, Jessore during Kharif-II season of 2016 to evaluate the germplasms of blackgram for searching of high yielding and yellow mosaic virus resistant genotypes. Significant difference were observed in every important parameters like scoring BYMV, no of pods/plant, 100 seed weight, and seed yield (kg/ha). Mean data shows that lowest BYMV score (2.89) was found in BBLXK-2004003-11 and highest score (4.89) in BBLXK-2004002-9. The line BBLXK-2004003-2, BBLXK-204001-15, BBLXK-204002-14, BBLXK-2004002-3, BBLXK-2004002-9, BBLXK-2004002-9 and BBLXK-2004003-11 are selected on the basis of disease severity and higher yield.

Keywords: Pulses, Lentil, Grain yield, Black gram, Virus

Location: RPRS, Madaripur, PRC, Ishurdi and RARS, Jessore, Bangladesh

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Crop-Soil-Water Management

Commodity: Black gram, Virus

Objectives:

To select some YMV resistant/tolerant lines of blackgram.

Methodology:

The experiment consisted of 19 entries with BARI Mash-1 as a check variety was conducted at RPRS, Madaripur, PRC, Ishurdi and RARS, Jessore during Kharif-II, 2016. The experiment was laid out in three replications in lattice design. Each entry was sown in a unit plot of 12m x 5m long with a spacing of 40 cm between rows. Spacing between two plots were 1m. Seeds were sown in the rows carefully by hands at 3 cm depth and then covered with soils on from 10-21 September 2016. Two weedings were done at 25 days and 45 days after sowing to keep plots free from weeds. Each of the entries were investigated from seedling to harvest and compared with check. Volium Flexi 300SC was sprayed 2 times for the control of pod borer. The crop was harvested within December 10-21, 2016. Data on yield and yield contributing characters were recorded from 10 randomly selected plants from each plot. Powdery mildew (Erysiphe poligoni or Oidium sp.) of blackgram was recorded on a 0-5 scoring scale (Bhatia and Thakur 1989). The scale described as 0= no disease incidence and 5= above 50% leaf area covered by powdery mildew disease. Mungbean yellow mosaic of mungbean was rated 0-8 scale used in this experiment described.

Achievement/Findings:

Considering BYMV scoring scale and yield together, the relative position of the genotypes with respect to check did not follow any definite trend. Considering overall performance, the lines BBLXK-2004003-2, BBLXK-204001-15, BBLXK-204002-14, BBLXK-2004002-3, BBLXK-2004002-9, BBLXK-2004002-9 and BBLXK-2004003-11 are selected for next year trial on the basis of disease severity and higher yield. Of them, BBLXK-2004003-11 was the best.
