Abstract

New sources of midge (Stenodiplosis sorghicola) resistance among local Sorghum bicolor cultivars were determined in experiments carried out from 1996-99 in Burkina Faso. Two hundred local landraces from Burkina Faso and other West African countries were screened for midge resistance. The 40 best cultivars were tested with resistant and susceptible controls during the 1999 rainy seasons, in midge-infested sites Kouaré and Farako-Bâ. The average percentage of midge-damaged spikelets in Kouaré varied from 0% in ICSV 745 to 45.3% in susceptible landrace 439. At Farako-Bâ, the percentage of damaged spikelets varied from 0.4% in ICSV 745 to 31.8% on the susceptible control Sariaso 10. Cultivar Tenlopieno had the highest percentage of damaged spikelets in both locations, but showed low visual midge damage scores.
