The field trial was conducted at Agricultural Research Station, Adilabad during the kharif season 2017. In the study eight soybean germplasms comprising of advanced breeding lines, released varieties were evaluated for resistance against stemfly and stem girdler. Some new parameters that have direct impact on grain yield have been used to categorize the germplasms into resistance groups. Accordingly, Basara, JS-335, JS-9305, DSB-2803 and KDS-756 were found to be highly resistant and KDS-869, MACS-1460 and RSC-1046 were found to be highly susceptible against stemfly and stem girdler.
