Tóm tắt

Symptoms of little leaf, leaf chlorosis and leaf malformations with mosaic mottling symptoms were observed in two brinjal varieties (Pusa Shyamla and Pusa Purple Cluster) in fields of IARI, New Delhi, India during 2014–2015. Electron microscopy, PCR and sequence analysis first time provided evidence of association of Candidatus Phytoplasma trifolii with potato virus X and potato virus Y in brinjal in India.
