Yellow mosaic (YM) of blackgram (Vigna mungo) has characteristics of a viral disease. Transmission did not occur by mechanical means, or by dodder (Cuscuta), but by grafting and whiteflies (Bemisia tabaci) from infected mungbean fields. Transovarian passage of the pathogen in whiteflies was not demonstrated. The same pathogen also affects mungbean (V. radiata), moth bean (V. aconitifolius), and soybean (Glycine max). Partial resistance to YM was found in blackgram lines that could be incorporated into susceptible varieties with otherwise desirable characteristics. [AS]
