| Résumé : |
A simple method to assess damage on screen sorghums for resistance to a sorghum panicle bug, eurystylus marginatus odh, using natural infestation was developed and evaluated at the station de recherche agronomique de Sotuba in 1989 and 1990. The method consisted in comparing the grain damage levels in unprotected panicles and panicles protected from bugs by the use of cages, plastic pollinating bags and insecticide. The efficacies of the three methods of protection were compared. Grain from unprotected panicles was extensively damaged. Grain mass (200 grains) was greatly reduced by bugs and grain vitrosity changed to floury. The rate of germination was severely lowered by bug damage and the number of floating or poor quality grains was much higher in unprotected paicles than in grains from unprotected panicles. Thes methods allow rapid and easy detection of resistance in sorghum varieties. |
