Abstract
Gladiolus grandiflorus is a bulbous ornamental plant popularly grown for its cut flowers of high commercial value. On a survey to the experimental fields at IARI, New Delhi, during 2016-2018. About 8% to 96 % disease incidence of leaf yellowing and streaks were observed in eleven varieties of gladiolus. The presence of ‘Candidatus Phytoplasma trifolii’ (16SrVI-D) subgroup in all the eleven symptomatic varieties was confirmed by PCR amplification using phytoplasma specific primer pairs P1/P7 and R16F2n/R16R2 and amplified 16Sr DNA sequence comparison. The presence of mixed infection with Cucumber mosaic virus (CMV) was also confirmed by electron microscopy and coat protein sequence analysis of gladioli samples. The results suggest the presence of mixed infection of 16SrI-D subgroup phytoplasmas and CMV associated with leaf yellowing and streaks symptoms in gladiolus varieties.
