Abstract
The components of resistance to sorghum midge, Contarinia sorghicola (Coquillett), in 20 genotypes of grain sorghum were assessed in six glasshouse trials by caging females on panicles. Fewer eggs were laid in sessile spikelets and a lower percentage of such spikelets was infested in all resistant lines compared with susceptible lines, indicating that ovipositional antixenosis was the major component involved. Pedicellate spikelets were not infested in lieu of sessile spikelets. In one line antixenosis to ovary‐feeding by larvae was indicated.Keywords
