Breeding for Resistance to Stem Borer ( Chilo partellus Swinhoe) in Sorghum uri icon

abstract

  • Stem borer (Chilo partellus Swinhoe) is the most important pest of sorghum. Progress has been made in developing borer-resistant breeding lines with moderate yield and acceptable grain quality. Sorghum variety, ICSV 700, has high levels of stem borer resistance across several seasons and locations. Borer resistance is a quantitatively inherited trait governed by additive and nonadditive genes. Epistatic gene effects are more pronounced under artificial borer infestation. Cytoplasmic effects appear to be present
