Screening of Some Sorghum Genotypes for Resistance to Sorghum Midge, Stenodiplosis sorghicola (Coq), under Rain-Fed Conditions, Sudan

Field trials were conducted at Abu-Naama Research Station Farm, Sudan during the rainy season 2012/013. Sixteen sorghum genotypes including the released and local varieties were screened and evaluated for resistance to sorghum midge. Based on the parameters such as midge damage rating (MDR), grain yield, panicle type and percent glumes coverage, varieties, Wad Ahmed, Tabat, Gadam Elhamam, Wad Baco and Mogud showed lower MDR ( < 2), short glumes and semi compact and compact panicle type. While the cultivars Tetron, Safra and Hagein Dura-1 showed higher MDR, long glumes and loose panicle type. The highest grain yield was obtained by Ajeb Seido (1551kg/fed), followed by Gadam Elhamam (1343 kg/fed) and Buttana (1225.1 kg/fed).
