FIELD SCREENING OF MUSKMELON GERMPLASM AGAINST CUCUMBER GREEN MOTTLED MOSAIC VIRUS

Abstract

Forty germplasm lines of muskmelon were screened for cucumber green mottled mosaic virus
(CGMMV) under field conditions a~d on the basis of two-year observations, average per cent disease
index (POI) was calculated. The maximum disease incidence was observed in Bagpat Local while
phoot (Cucumis melo var. momordica) showed minimum disease incidence of CGMMV. Out of 40
germplasm, 16 were observed to be resistant while 17 and 7 germplasm, showed moderately resistant
and susceptible reaction respectively. The resistant germplasm can be utilized for evolving disease
resistant varieties with desirable quality traits.
