Abstract

Thirty-five pearl millet cultivars of short, medium and long maturity cycle were screened in Senegal during 1985–1986 crop seasons to study field reaction to the attack of stalk borer, Coniesta (Acigona) ignefusalis Hmps.; spike worm, Heliocheilus (Raghuva) albipunctella De Joannis; millet midge, Geromyia penniseti Felt; head smut, Tolysporium penicillariae Bref; and ergot, Claviceps fusiformis Lov. Insect and disease incidence varied considerably depending upon cultivar maturity cycle. Least susceptible cultivars were IBV-8001 and P8 against spike worm; Zalla, NKK, P8 and M2D2 against head smut, and Ex-Darou against ergot. Cultivation of IBV-8001 has been suggested in northern and central Senegal. However, studies on identification and utilization of resistance sources of wide genetic diversity and multilocational tests may be necessary.

Résumé

Trente cinq cultivars du petit mil de court, moyen et long cycle de maturité ont été criblés au Sénégal pendant les saisons 1985–86 afin d'étudier la reaction au champ à l'attaque du foreur des tiges, Coniesta (Acigona) ignefusalis Hmps; de la chenille mineuse de l'épi, Heliocheilus (Raghuva) albipunctella De Joannis; de la cécidomyie du mil, Geromyia penniseti Felt; et du charbon de l'épi, Tolysporium penicillariae Bref; et de l'ergot, Claviceps fusiformis Lov. L'incidence des insectes et des maladies a varié considérablement en fonction du cycle de maturité des cultivars. Les cultivars les plus moins attaqués étaient IBV–8001 et P8 contre la mineuse de l'épi; Zalla, NKK, P8 et M2D2 contre le charbon et Ex-Darou contre l'ergot. Cultivation d'IBV-8001 a été suggérée dans les régions du nord et du centre du Sénégal. Pourtant, les études sur l'identification et l'utilisation des sources de résistance d'une diversité génétique et les essais multilocaux seront nécessaires.
