Abstract

First report of Mungbean yellow mosaic India virus infecting pumpkin in India.

Abstract

During a survey in 2017 in Madhya Pradesh state, India, greenhouse-cultivated pumpkin (Cucurbita pepo) plants exhibiting leaf symptoms of mosaic and crumpling, typical of begomovirus infection were observed. Though diseased plants grew to the same size as symptomless plants, there was no flower formation leading to no fruit production, i.e. 100% yield loss. Whiteflies were found associated with the plants. Young diseased leaves were collected to identify the cause of the suspected virus infection. Based on polymerase chain reaction assay and BLAST analysis of the nucleotide sequences, the causal agent was identified as Mungbean yellow mosaic India virus (MYMIV). This is thought to be the first definitive report of MYMIV infection on pumpkin from India.
