Abstract
The present investigation entitled “Characterization of Begomoviruses Causing
Yellow Mosaic Disease in Different Host Plants” was carried out in the Department of
Plant Pathology, College of Agriculture and Technology, Banda, UP during 2021- 2023.
Disease survey was conducted in legumes and cucurbits growing villages of Banda district
in Uttar Pradesh, in which, the incidence of yellow mosaic disease in leguminous hosts
ranged from 23.50- 54.23%, 22.11-41.58%, 10.42- 50.45%, 18.36- 40.76%, 10.98- 23.50%
and 22.78- 45.95% in mungbean, urdbean, pigeon pea, cowpea, Dolichos bean and French
bean, respectively. Maximum mean disease incidence was recorded in mungbean (38.66%)
followed by French bean (35.01%), urdbean (31.87%), pigeon pea (30.74%), cowpea
(28.19%) and Dolichos bean (19.01%). YMD incidence in sponge gourd, pumpkin,
cucumber and bitter guard ranged from 25.75- 44.27%, 18.58- 39.06%, 17.67- 33.47% and
22.0- 37.83%, respectively. Maximum mean disease incidence was recorded in sponge
gourd (33.88%) followed by bitter gourd (28.99%), pumpkin (28.42%) and cucumber
(24.95%). Yellow mosaic disease was characterized on fifteen different host plants which
included six legumes, four cucurbits and five weed hosts on the basis of various symptoms
viz., yellow mosaic, mottling, leaf curling, vein clearing, vein banding, puckering,
chlorosis, malformation, reduced growth etc. PCR products of 13 out of 16 samples
showed positive amplification with MYMIV DNA-A CP primer only whereas no
amplification was reported with DNA-A CP of MYMV, HgYMV and DoYMV. BLAST
analysis of 13 MYMIV sequences resulted that eight sequences from mungbean, moth
bean, urdbean, cowpea, sponge gourd, French bean, bitter gourd and wild kakdi showed
homology with the MYMIV strains.
