The present investigation was carried out to determine the nature of association between seed yield and its contributing traits under yellow mosaic virus (YMV) stress using correlation analysis. A total of 30 genotypes, including six generations derived from five mungbean crosses, were evaluated in a randomized block design with three replications. Phenotypic and genotypic correlation coefficients were computed for twelve quantitative and disease-related characters. The results revealed that seed yield per plant exhibited strong and significant positive correlations with pods per plant, plant height, pod length, seeds per pod, and 100-seed weight at both phenotypic and genotypic levels. Conversely, disease incidence, percent disease index (PDI), and area under disease progress curve (AUDPC) showed significant negative associations with yield and its components. These findings highlight the importance of selecting positively correlated traits while minimizing disease effects for enhancing yield potential in MYMV-affected environments.
