Abstract:
Soybean (Glycine max (L.) Merrill) is a widely cultivated oilseed crop with a chromosome count of 2n=40. Soybean yellow mosaic virus (SYMV) poses a significant challenge to the successful cultivation of soybeans in various nations. The transmission of SYMV occurs through the whitefly known as Bemisia tabaci Gennadius. The lowest occurrence of the disease and reduction of the vector population was observed when applying the recommended dose of Imidacloprid 17.8% SL (T₁). The control treatment had the highest disease incidence and vector population. In the present research, we evaluated ten different soybean varieties for their resistance to Soybean Yellow Mosaic Virus (SYMV) in a field conditions, it was found that three varieties, namely JS 97-52, JS 21-05, and RSC 1142, demonstrated resistance to soybean yellow mosaic virus. Furthermore, the study identified six genotypes (JS 20-29, JS 20-69, RVS 24, JS 95-60, JS 20-94 and JS 93-05) with a moderate level of resistance, while only one genotype, JS 335, was found to be highly susceptible. The most effective strategy for managing soybean yellow mosaic virus is to employ these resistant varieties.
