Abstract
In field and screenhouse experiments, pollination of inflorescences of three pearl millet F1 hybrids and two male‐sterile (ms) lines with fresh viable pollen 5–8 days after inoculation with a Tolyposporium penicillariae sporidial suspension reduced smut severities significantly compared with inoculated, non‐pollinated control plants. Smut development was not significantly reduced in a ms line following pollination of inoculated inflorescences with pollen of low viability. The implications of these findings in developing an effective screening technique for smut resistance and in controlling this disease in pearl millet are discussed.
