Identification of Maize ilea mays L.) Inbred Lines Resistant for Late Wilt Dcaused by Harpophora maydis

摘要

Late wilt disease caused by Harpophora maydis is one of the important diseases in maize.The disease shows its symptoms during flowering when the plants are about to tassel. Considering that host plant resistance is the most economical and eco-friendlyapproach to mitigate losses due to late wilt, 155 maize inbred lines were screened under field conditions by challenging them with artificial inoculation of the pathogen using specialized inoculators designed for the purpose. Of these, 9 were resistant,108 lines were moderately susceptible, 24 were susceptible and remaining 14 lines were highly susceptible. The identified late wilt resistant inbred lines could be used for developing late wilt resistant population / inbreds or in strategic and basic research.
