Screening of soybean genotypes against stem fly, Melanagromyza sojae (Zehntner)

J Upadhyay

To study the screening of nine soybean genotypes with one check variety (JS 20-29) were screened for resistance to stem fly, a trial was sown at the Experimental Field Department of Plant Breeding & Genetics J.N.K.V.V. Jabalpur (M.P.) during Kharif season 2014-15. To record the infestation of stem fly and tunnel in stem caused by its maggots, is taken by removal method i.e.10 plants/plot were uprooted at randomly and split open vertically at 30 days and at maturity. Plant height and tunnel length were measured for calculating per cent stem tunneling. Among genotypes, JS 20-122 recorded the least per cent stem tunneling (4.67%) which was significantly superior to all other genotypes and check. The maximum per cent tunneling (20.82%) was observed in genotype JS 20-111. On the basis of incidence of stem fly, genotype JS 20-108 was found to be less susceptible and check variety JS 20-29 was highly susceptible.
