“…It shows that mungbean germplasm is deficient of natural resistance against mungbean yellow mosaic disease. This study confirmed the findings that the resistance against mungbean yellow mosaic virus is very scarce (Ahmad, 1975;Sahoo and Hota, 1991;Singh et al, 1996;Saleem et al, 1998;Bashir, 2005;Shad et al, 2006;Akhtar et al, 2011;Iqbal et al, 2011). This scarcity of resistant source is actually due to low proportion of recessive alleles (Sudha et al, 2013) in natural gene pool which also implies that recessive allele is mutated form of wild gene conferring susceptibility.…”

“…Hence germplasm was evaluated for two consecutive years to confirm that resulting resistance is only due to genotypic basis not due to lack of vector attack or any other environmental condition. The two-year evaluation discovered high level of genetic diversity among the genotypes for MYMD resistance and variable behavior of genotypes across the seasons and years (Akhtar et al, 2011). An important aspect in breeding for disease resistance is accurate measurement of disease or disease resistance indicators (Akhtar and Khan, 2002) because it ensures the identification of a real resistance source.…”

Mungbean yellow mosaic disease is most damaging disease of mungbean in all of its growing areas. Genetic resistance is a viable and environment friendly solution, for which resistance source is prerequisite. Total 83 mungbean genotypes were experimented for their resistance potential against disease for two consecutive years 2014 and 2015 during summer season. Infection percentage and disease severity based scoring scales were compared for their discrimination potential for screening. Disease severity based scoring scale was found superior to infection percentage based scale because it categorized genotypes into five groups while only two groups were generated by later. Infection %age ranged from 33.33 to 100% while disease severity index varied from 10 to 75%. Only one genotype (NM 6-68-2) was found comparatively tolerant (D.I. 10%) during both the years. Biplot analysis depicted that behavior of some genotypes showed instability in the second year while most of the genotypes showed a stable resistance/susceptibility levels during both the years. Accession NM 1-32-1 was highly susceptible genotype during both the years. Disease severity showed maximum correlation with chlorophyll-a reduction followed by 100 seed weight while it had high level of association with yield. Analytical dissection of correlation among traits revealed that direct effect of disease on yield reduction was negligible but it caused yield reduction via reduced harvest index and 100 seed weight. It is concluded that resistance sources are very scarce and resistance level is very low but still these sources can be exploited in breeding programs. For the improvement of genetic variability induced mutation could be another option.

“…In addition, the rapid development of the viral recombinant strains and the presence of wide host range for the vector Bemesia tabaci possess a serious constraint to the mungbean production in India. Akhtar et al, 14 reported that identification of the resistance source is the most reliable and economical method for the management of this virus as no virucide is available for the management of MYMV disease. Even though several genotypes and varieties have been identified showing resistance against MYMV, lack of durable resistance has been observed in most of the cases.…”

Mungbean Yellow Mosaic Virus (MYMV), transmitted through the white fly (Bemisia tabaci) in the persistent manner is one of the most pernicious diseases of Vigna species. Twenty-five genotypes of mungbean [Vigna radiata (L.) Wilczek] were sown in randomized block design with two replications during the summer season in 2015. The test entries were evaluated against the mungbean yellow mosaic virus (MYMV) under natural field conditions. Screening for MYMV resistance was done by planting infector rows along with the test entries. Percent Disease Incidence (PDI) was calculated. The differential response against MYMV observed and the results revealed that most of the genotypes studied were characterized as moderately susceptible to highly susceptible. In spite of the variable response to MYMV, IPM 02-03, KM 2241, PDM 139, Pusa 0672, HUM 16, ML 1464 and TARM-1 of the mungbean genotypes exhibited resistance during the summer, 2015. The present investigation suggests that these genotypes could possibly be utilized as donors to develop MYMV resistant lines MYMV resistance by introgressing in agriculturally important but MYMV susceptible genotypes. Consequently, in the near future, the improved varieties may surfeit the sustainable agriculture production in the biotic stress prone areas.

“…Mungbean germplasm was screened against MYMV under field conditions, and revealed four genotypes resistant, eight moderately resistant, and 30 moderately susceptible to MYMV (Iqbal et al, 2011). Mungbean genotypes were studied against YMV, and 35 lines were found moderately resistant to YMV with significant variability in yieldcontributing traits (Akhtar et al, 2011). However, the YMV resistance/tolerance was studied in mungbean germplasm, and some of the genotypes also produced a good yield despite being highly susceptible to YMV disease (Habib et al, 2007), which might be due to low disease pressure.…”

“…In mungbean yellow mosaic India virus (MYMIV), using whitefly as vector, 164 mungbean genotypes were screened; all genotypes were systemically infected with virus, significant variations were observed in responses among genotypes, and 35 genotypes were moderately resistant to the virus showing significant differences for yield contributing traits (Akhtar et al, 2011). The differential response of 100 accessions of mungbean to MYMV was determined and used to categorize mungbean into resistant and susceptible depending upon severity of infection.…”

Moth bean [Vigna aconitifolia (Jacq.) Marechal] susceptibility to yellow mosaic virus (YMV) purged the crop from the farming system. Therefore, genotype-by-environment interaction (GEI) and biplot studies were undertaken to develop YMV-resistant moth bean cultivars from the germplasm. The germplasm was acquired from the National Agricultural Research Centre (NARC), Islamabad and from the farm fields in two provinces, Punjab and Sindh, Pakistan. Two different groups of moth bean genotypes were screened for YMV versus seed yield (11 genotypes) and YMV versus fodder yield (10 genotypes) over three years (2006)(2007)(2008) in three locations in Pakistan [D.I.Khan Agriculture Research Station (ARS), Serai Naurang ARS, and Karak ARS]. In all germplasm, four moth bean lines were identified as highly resistant to YMV with maximum grain (013393-C, 013388) and fodder (DMB-118-E, DMB-118-A) yields across all years and locations. Genotype, environment, GEI, and biplot analysis revealed that two moth bean lines (013393-C and DMB-118-E) showed the lowest YMV scoring (1) and maximum grain (33.40, 29.70, and 33.98 g plant -1 ) and fodder yields (15.30, 17.40, and 15.35 t ha -1 ) compared with susceptible checks, respectively. Keeping in view the genetic potential of YMV-resistance and the high grain and fodder yields of two moth bean lines (013393-C, DMB-118-E), the Provincial Seed Council (PSC) of Khyber Pakhtunkhwa, Pakistan approved the two lines with the highest grain and fodder yields as new moth bean cultivars, naming them Dera Moth and Green Moth, respectively.
