Host plant resistance of sorghum genotypes against shoot fly (Atherigona soccata Rondani) and stem borer (Chilo partellus Swinhoe) in Madhya Pradesh-India

Abstract

Field trials were carried out during Kharif 2014-15 to evaluate host plant resistance for shoot fly and stem borer in 14 genotypes of sorghum. Based upon hierarchical clustering considering parameters of stem borer per cent plant infestation, dead heart caused by stem borer, stem tunneling, peduncle tunneling, number of larvae/plant and number of tunnel per plant genotypes CSH-22SS, IS-22186, CSH-24MF, CSX-24SS and ICSSH-28 were found less susceptible to stem borer and genotype SSG-59 and N-610 was found highly susceptible to stem borer. And also genotypes IS-22670, ICSSH-28 was found less susceptible to shoot fly.
