Identification and Characterization of Fungi Species Associated of Pearl Millet (Pennisetum glaucum R. Br.) to Seed, Leaves and Physiological Maturity Stage in Burkina Faso

---

Résumé

Crops seed are sometimes susceptible to parasitic diseases related storage conditions. In response to this situation, for all material vegetal intended for introduction into a program breeding, it is important to characterized fungal diseases associated. Pearl millet from
ICRISAT-Niger gene bank and Biosciences laboratory in Burkina Faso. A block Fisher with 3 repetitions is been carried in experimental station in Burkina Faso during the period
July to October 2024, led to the Phytopathology Laboratory of Joseph KI-ZERBO University. Mathur & Kongsdal (2003) methods have been used to characterized the
different fungi. A total of 14 fungal isolates were obtained for all countries with Curvularia sp. as specie predominating. Furthermore, 10 fugal isolates on seeds, 10 isolates fungal on leaves, and 8 isolates fungal on mush seeds. However, significant differences were been
identified between countries. Aspergillus flavus, Aspergillus niger, Bipolaris sp., Curvularia sp., Fusarium sp.4, Fusarium sp.5, and Phoma sorghina are species common to
all three countries. As for the other species, Fusarium sp.3, Fusarium sp.6, Penicillium sp., and Rhizopus sp. were found alone in pearl millet accessions from Togo. The species
Fusarium sp.2 was found alone in pearl millet from Burkina Faso and India. Curvularia sp. (84.84%) and Bipolaris sp. (37.18%) found on the seeds were also found on the leaves and mushy seeds from these three countries. This study reported that Curvularia is the main disease dominant in collection.
