Abstract: Mung bean yellow mosaic virus (MYMV) is one of the most important diseases affecting mung beans, transmitted by the whitefly (Bemisia tabaci). MYMV poses a significant threat to mung bean production, emphasizing the need to identify resistant genotypes for the development of effective disease control strategies. In this study, we screened 60 mung bean germplasm under field conditions during the Yala season of 2022 to identify stable MYMV-resistant lines. Infector rows were planted alongside the test entries, and disease incidence and severity were observed under natural conditions. The genotypes studied were categorized as highly resistant to highly susceptible, with none of the test entries appearing to be highly resistant. We identified MIMB 909, MIMB 913, MIMB 916, MIMB 918, MI 7, MIMB 907, MIMB 908, MIMB 911, MIMB 912, MIMB 914, MIMB 923, MIMB 926, MIMB 933, MIMB 937, MIMB 938, MIMB 941, MIMB 945, MIMB 982, and MIMB 983 as resistant and moderately resistant genotypes, respectively. These genotypes could serve as parental lines in a mung bean breeding program focused on developing more MYMV-resistant varieties. Further studies are needed to evaluate the stability of resistance in these genotypes across multiple growing seasons and locations. The research contributes Valuable insight into the dynamics of MYMV infection in mung bean providing a foundation for developing diseaseresistant varieties and sustainable crop management strategies. Consequently, in the near future, the improved varieties may surfeit the sustainable agriculture production in the biotic stress prone areas.
