Abstract/ Executive Summary:

An experiment was conducted at RPRS, Madaripur during kharif-1 season of 2014 to evaluate the performance of mungbean genotypes for high yielding and resistant source again Mungbean Yellow Mosaic Virus (MYMV). Six selected advanced lines with a check BARI Mungbean-6 were evaluated in the trial. The lines were VC-6173, VC-3960A-88, GK-22, SM2-134, BMXK₁-0300011 and BMXK₂-05009. BARI Mungbean-6 gave the highest (2.00 t/ha) yield followed by VC-6173 (1.95 t/ha) the line and the lowest yield found in the line GK-22 (0.86 t/ha). The line VC-6173 give lowest MYMV score (1.30) where the line BMXK2-05009 gave the highest score (4.66). So, VC- 6173 can be tested regionally to release it as MYMV resistant variety.

Keywords: mungbean, Yellow Mosaic Virus, Resistant variety.

Location: RPRS, Madaripur

Start Date: 00-00-2014

End Date: 00-00-2014

Program Area: Pest Management

Commodity: Virus, Mungbean

Objectives:

To find out the suitable mungbean lines which are more or less tolerant to MYMV having the high yielding capacity and to use resistant host as well as is most important to find out useful way of management of this disease

Methodology:

The experimentl was conducted at Regional Pulse Research Station (RPRS), BARI, Madaripur during kharif-1 2014 under rain fed condition. Six genotypes/lines viz. VC-6173, VC-3960A-88, GK-22, SM2-134, BMXK₁-0300011 and BMXK₂-05009 and one check variety BARI Mungbean-6 were evaluated in the trial. The experiment was laid out in RCB design with two replications. The spacing was 50 cm X 10 cm. Seeds were sown on March 03, 2014. Two weeding were done to keep the crop weed free up to first picking. Two picking was done within May 24, 2014. Data on yield contributing characters were recorded from 10 randomly selected plants from each plot and grain yield (t/ha) were recorded from whole plot and analyzed statistically through MSTAT-C.

Achievement/Findings:

Experimental results revealed that all the yield components were statistically significant. The best (1.30) (resistance) MYMV score obtained in the line VC-6173 and the poorest (4.66) score was found in the line BMXK₂-05009. The highest plant height (42.13 cm) was recorded in the line VC-6173 and the lowest plant height (37.27 cm) was recorded in the line BMXK₂-05009. The maximum number of pods per plant (42.33) were produced by BARI Mungbean-6 followed by (40.00) in VC-6173 and minimum number of pods per plant (23.00) produced by GK-22. There was no significant variation in pod length among the lines. The highest (9.93) number of seeds per pod was found in BARI Mungbean-6 followed by (9.80) the line VC-6173(9.80) and the lowest (8.86) number of seeds per pod was found in the line BMXK₂-05009. The highest 100 seed weight (6.33 g) observed in BARI Mungbean-6 and the lowest 100 seed weight (5.00 g) found in the line SM2-134 and BMXK₁-0300011. Among the entries BARI Mungbean-6 gave the highest yield (2.00 t/ha) followed by VC-6173 (1.95 t/ha). The lowest yield was recorded in GK-22 (0.86 t/ha). The line VC-6173 may be selected as short duration, yield & low disease (days to maturity-53), resistant to yellow mosaic virus (score 1.30 out of 1-9 scale) and also production per hectare (1.95 t/ha). So, the line VC-6173 can be tested regionally to release it as MYMV resistant variety.
